Hardware Features
The Micro810 12-pt controllers are smart relays with high current relay output
models and can be configured through the embedded LCD display without
programming software. It can also function as a micro PLC with the same
programming capabilities as the other Micro800 controllers.
Micro810 controllers do not support Micro800 plug-in modules, but do support
a USB adapter, and an LCD module, which can be used as a backup memory
module.
24V DC powered controllers accommodate any 24V DC output power supply
that meets minimum specifications such as the optional Micro800 power supply
(2080-LC10-12QWB, 2080-LC10-12QBB only).

Disconnecting Main Power
WARNING: Explosion Hazard
Do not replace components, connect equipment, or disconnect equipment
unless power has been switched off.
The main power disconnect switch should be located where operators and
maintenance personnel have quick and easy access to it. In addition to
disconnecting electrical power, all other sources of power (pneumatic and
hydraulic) should be de-energized before working on a machine or process
controlled by a controller.
Rockwell Automation Publication 2080-UM001D-EN-E - September 2012 7
Chapter 2 About Your Controller
Safety Circuits
WARNING: Explosion Hazard
Do not connect or disconnect connectors while circuit is live.
Circuits installed on the machine for safety reasons, like overtravel limit switches,
stop push buttons, and interlocks, should always be hard-wired directly to the
master control relay. These devices must be wired in series so that when any one
device opens, the master control relay is de-energized, thereby removing power to
the machine. Never alter these circuits to defeat their function. Serious injury or
machine damage could result.
Power Distribution
There are some points about power distribution that you should know:
• The master control relay must be able to inhibit all machine motion by
removing power to the machine I/O devices when the relay is deenergized. It is recommended that the controller remain powered even
when the master control relay is de-energized.
• If you are using a DC power supply, interrupt the load side rather than the
AC line power. This avoids the additional delay of power supply turn-off.
The DC power supply should be powered directly from the fused
secondary of the transformer. Power to the DC input and output circuits
should be connected through a set of master control relay contacts.
Periodic Tests of Master Control Relay Circuit
Any part can fail, including the switches in a master control relay circuit. The
failure of one of these switches would most likely cause an open circuit, which
would be a safe power-off failure. However, if one of these switches shorts out, it
no longer provides any safety protection. These switches should be tested
periodically to assure they will stop machine motion when needed.
8 Rockwell Automation Publication 2080-UM001D-EN-E - September 2012
About Your Controller Chapter 2
Power Considerations
The following explains power considerations for the micro controllers.
Isolation Transformers
You may want to use an isolation transformer in the AC line to the controller.
This type of transformer provides isolation from your power distribution system
to reduce the electrical noise that enters the controller and is often used as a stepdown transformer to reduce line voltage. Any transformer used with the
controller must have a sufficient power rating for its load. The power rating is
expressed in volt-amperes (VA).
Power Supply Inrush
During power-up, the Micro800 power supply allows a brief inrush current to
charge internal capacitors. Many power lines and control transformers can supply
inrush current for a brief time. If the power source cannot supply this inrush
current, the source voltage may sag momentarily.
The only effect of limited inrush current and voltage sag on the Micro800 is that
the power supply capacitors charge more slowly. However, the effect of a voltage
sag on other equipment should be considered. For example, a deep voltage sag
may reset a computer connected to the same power source. The following
considerations determine whether the power source must be required to supply
high inrush current:
• The power-up sequence of devices in a system.
• The amount of the power source voltage sag if the inrush current cannot be
supplied.
• The effect of voltage sag on other equipment in the system.
If the entire system is powered-up at the same time, a brief sag in the power source
voltage typically will not affect any equipment.
Loss of Power Source
The optional Micro800 AC power supply is designed to withstand brief power
losses without affecting the operation of the system. The time the system is
operational during power loss is called program scan hold-up time after loss of
power. The duration of the power supply hold-up time depends on power
consumption of controller system, but is typically between 10 milliseconds and 3
seconds.
Rockwell Automation Publication 2080-UM001D-EN-E - September 2012 9
Chapter 2 About Your Controller
TIP
Input States on Power Down
The power supply hold-up time as described above is generally longer than the
turn-on and turn-off times of the inputs. Because of this, the input state change
from “On” to “Off” that occurs when power is removed may be recorded by the
processor before the power supply shuts down the system. Understanding this
concept is important. The user program should be written to take this effect into
account.
Other Types of Line Conditions
Occasionally the power source to the system can be temporarily interrupted. It is
also possible that the voltage level may drop substantially below the normal line
voltage range for a period of time. Both of these conditions are considered to be a
loss of power for the system.
Preventing Excessive Heat
Master Control Relay
For most applications, normal convective cooling keeps the controller within the
specified operating range. Ensure that the specified temperature range is
maintained. Proper spacing of components within an enclosure is usually
sufficient for heat dissipation.
In some applications, a substantial amount of heat is produced by other
equipment inside or outside the enclosure. In this case, place blower fans inside
the enclosure to assist in air circulation and to reduce “hot spots” near the
controller.
Additional cooling provisions might be necessary when high ambient
temperatures are encountered.
Do not bring in unfiltered outside air. Place the controller in an enclosure
to protect it from a corrosive atmosphere. Harmful contaminants or dirt
could cause improper operation or damage to components. In extreme
cases, you may need to use air conditioning to protect against heat buildup within the enclosure.
A hard-wired master control relay (MCR) provides a reliable means for
emergency machine shutdown. Since the master control relay allows the
placement of several emergency-stop switches in different locations, its
installation is important from a safety standpoint. Overtravel limit switches or
mushroom-head push buttons are wired in series so that when any of them opens,
the master control relay is de-energized. This removes power to input and output
device circuits. Refer to the figures on pages 13 and 14.

About Your Controller Chapter 2
TIP
TIP
WARNING: Never alter these circuits to defeat their function
since serious injury and/or machine damage could result.
If you are using an external DC power supply, interrupt the DC output
side rather than the AC line side of the supply to avoid the additional
delay of power supply turn-off.
The AC line of the DC output power supply should be fused.
Connect a set of master control relays in series with the DC power
supplying the input and output circuits.
Place the main power disconnect switch where operators and maintenance
personnel have quick and easy access to it. If you mount a disconnect switch
inside the controller enclosure, place the switch operating handle on the outside
of the enclosure, so that you can disconnect power without opening the
enclosure.
Whenever any of the emergency-stop switches are opened, power to input and
output devices should be removed.
When you use the master control relay to remove power from the external I/O
circuits, power continues to be provided to the controller’s power supply so that
diagnostic indicators on the processor can still be observed.
The master control relay is not a substitute for a disconnect to the controller. It is
intended for any situation where the operator must quickly de-energize I/O
devices only. When inspecting or installing terminal connections, replacing
output fuses, or working on equipment within the enclosure, use the disconnect
to shut off power to the rest of the system.
Do not control the master control relay with the controller. Provide the
operator with the safety of a direct connection between an emergencystop switch and the master control relay.
Using Emergency-Stop Switches
When using emergency-stop switches, adhere to the following points:
• Do not program emergency-stop switches in the controller program. Any
emergency-stop switch should turn off all machine power by turning off
the master control relay.
• Observe all applicable local codes concerning the placement and labeling
of emergency-stop switches.
Rockwell Automation Publication 2080-UM001D-EN-E - September 2012 11
Chapter 2 About Your Controller
TIP
• Install emergency-stop switches and the master control relay in your
system. Make certain that relay contacts have a sufficient rating for your
application. Emergency-stop switches must be easy to reach.
• In the following illustration, input and output circuits are shown with
MCR protection. However, in most applications, only output circuits
require MCR protection.
The following illustrations show the Master Control Relay wired in a grounded
system.
In most applications input circuits do not require MCR protection;
however, if you need to remove power from all field devices, you must
include MCR contacts in series with input power wiring.

Module Spacing
Maintain spacing from objects such as enclosure walls, wireways and adjacent
equipment. Allow 50.8 mm (2 in.) of space on all sides for adequate ventilation.
An exception to this spacing guideline is allowed for the side at which you are
connecting the optional power supply, 2080-PS120-240VAC.
DIN Rail Mounting
Rockwell Automation Publication 2080-UM001D-EN-E - September 2012 15
The module can be mounted using the following DIN rails: 35 x 7.5 mm x 1 mm
(EN 50 022 - 35 x 7.5).
For environments with greater vibration and shock concerns, use the
panel mounting method, instead of DIN rail mounting.
Before mounting the module on a DIN rail, use a flat-blade screwdriver in the
DIN rail latch and pry it downwards until it is in the unlatched position.
Chapter 3 Install Your Controller
1. Hook the top of the DIN rail mounting area of the controller onto the
DIN rail, and then press the bottom until the controller snaps onto the
DIN rail.
2. Push the DIN rail latch back into the latched position.
Use DIN rail end anchors (Allen-Bradley part number 1492-EAJ35 or
1492-EAHJ35) for vibration or shock environments.
To remove your controller from the DIN rail, pry the DIN rail latch downwards
until it is in the unlatched position.
Panel Mounting
The preferred mounting method is to use four M4 (#8) screws per module. Hole
spacing tolerance: ±0.4 mm (0.016 in.).
Follow these steps to install your controller using mounting screws.
1. Place the controller against the panel where you are mounting it. Make sure
the controller is spaced properly.
2. Mark drilling holes through the mounting screw holes and mounting feet
then remove the controller.
3. Drill the holes at the markings, then replace the controller and mount it.
Leave the protective debris strip in place until you are finished wiring the
controller and any other devices.

Wiring Requirements
TIP
Wire Your Controller
WARNING: Before you install and wire any device, disconnect power
to the controller system.
WARNING: Calculate the maximum possible current in each power
and common wire. Observe all electrical codes dictating the maximum
current allowable for each wire size. Current above the maximum
ratings may cause wiring to overheat, which can cause damage.
United States Only: If the controller is installed within a potentially
hazardous environment, all wiring must comply with the requirements
stated in the National Electrical Code 501-10 (b).
Chapter
4
• Allow for at least 50 mm. (2 in.) between I/O wiring ducts or terminal
strips and the controller.
• Route incoming power to the controller by a path separate from the device
wiring. Where paths must cross, their intersection should be
perpendicular.
Do not run signal or communications wiring and power wiring in the
same conduit. Wires with different signal characteristics should be
routed by separate paths.
• Separate wiring by signal type. Bundle wiring with similar electrical
characteristics together.
• Separate input wiring from output wiring.
• Label wiring to all devices in the system. Use tape, shrink-tubing, or other
dependable means for labeling purposes. In addition to labeling, use
colored insulation to identify wiring based on signal characteristics. For
example, you may use blue for DC wiring and red for AC wiring.

of surge suppression to protect and extend the operating life of the controllers
output contacts is required. Switching inductive loads without surge suppression
can significantly reduce the life expectancy of relay contacts. By adding a
suppression device directly across the coil of an inductive device, you prolong the
life of the output or relay contacts. You also reduce the effects of voltage
transients and electrical noise from radiating into adjacent systems.
The following diagram shows a typical PLC's output with a suppression device.
We recommend that you locate the suppression device as close as possible to the
load device.
If the outputs are DC, we recommend that you use an 1N4004 diode for surge
suppression, as shown below. For inductive DC load devices, a diode is suitable. A
1N4004 diode is acceptable for most applications. A surge suppressor can also be
used. See page 19
for recommended suppressors. As shown below with a typical
PLC's output, these surge suppression circuits connect directly across the load
device.
18 Rockwell Automation Publication 2080-UM001D-EN-E - September 2012
Suitable surge suppression methods for inductive AC load devices include a
varistor, an RC network, or an Allen-Bradley surge suppressor, all shown below.
These components must be appropriately rated to suppress the switching

Because of the variety of applications and environments where controllers are
installed and operating, it is impossible to ensure that all environmental noise will
be removed by input filters. To help reduce the effects of environmental noise,

install the Micro800 system in a properly rated (for example, NEMA) enclosure.
Make sure that the Micro800 system is properly grounded.
A system may malfunction due to a change in the operating environment after a
period of time. We recommend periodically checking system operation,
particularly when new machinery or other noise sources are installed near the
Micro800 system.
Analog Channel Wiring Guidelines
Consider the following when wiring your analog channels:
• The analog common (COM) is connected to power supply common
inside the module. These terminals are not electrically isolated from the
system.
• Analog channels are not isolated from each other.
• Use Belden 8761, or equivalent, shielded wire.
• Under normal conditions, the drain wire (shield) should be connected to
the metal mounting panel at field side (earth ground). Keep the shield
connection to earth ground as short as possible.
• To ensure optimum accuracy for voltage type inputs, limit overall cable
impedance by keeping all analog cables as short as possible. Locate the I/O
system as close to your voltage type sensors or actuators as possible.
Minimize Electrical Noise on Analog Channels
Inputs on analog channels employ digital high-frequency filters that significantly
reduce the effects of electrical noise on input signals. However, because of the
variety of applications and environments where analog controllers are installed
and operated, it is impossible to ensure that all environmental noise will be
removed by the input filters.
Several specific steps can be taken to help reduce the effects of environmental
noise on analog signals:
• install the Micro800 system in a properly rated enclosure, for example,
NEMA. Make sure that the Micro800 system is properly grounded.
• use Belden cable #8761 for wiring the analog channels, making sure that
the drain wire and foil shield are properly earth grounded.
• route the Belden cable separately from any AC wiring. Additional noise
immunity can be obtained by routing the cables in grounded conduit.
