Hardware Overview

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.

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.

	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 step-
	down 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

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 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.

TIP	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 build-
	up within the enclosure.

Master Control Relay

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.

10	Rockwell Automation Publication 2080-UM001D-EN-E - September 2012

About Your Controller	Chapter 2

WARNING: Never alter these circuits to defeat their function since serious injury and/or machine damage could result.

TIP	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.

TIP	Do not control the master control relay with the controller. Provide the
	operator with the safety of a direct connection between an emergency-
	stop 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

•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.

TIP	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

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).

TIP 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.

Rockwell Automation Publication 2080-UM001D-EN-E - September 2012

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.

Wire Your Controller

Wiring Requirements

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).

•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.

TIP	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.

Use Surge Suppressors

Because of the potentially high current surges that occur when switching inductive load devices, such as motor starters and solenoids, the use of some type

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.

Controller I/O Wiring	Minimize Electrical Noise
	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,

Chapter 4 Wire Your Controller

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.
