Ground the Controller
The controller is functionally grounded through its DIN rail connection. A protective earth
ground connection is required and is provided through a separate grounding screw on the upper
left of the housing and marked with the grounding symbol .
You must also provide an acceptable grounding path for each device in your application. For
more information on proper grounding guidelines, refer to the Industrial Automation Wiring
and Grounding Guidelines, publication 1770-4.1
ATTENTION: This product is grounded through the DIN rail to chassis ground.
Use zinc-plated yellow-chromate steel DIN rail to assure proper grounding. The
use of other DIN rail materials (for example, aluminum or plastic) that can
corrode, oxidize, or are poor conductors, can result in improper or intermittent
grounding. Secure DIN rail to mounting surface approximately every 200 mm
(7.8 in.) and use end-anchors appropriately.

6 GuardPLC 1800 Controllers
Wire the Controller
The following section describe how to connect the voltage supply and wire the controller’s
digital inputs and outputs.
Connect the Voltage Supply
The 24V DC voltage supply must feature galvanic isolation (in accordance with
EN 60950 or UL 1950) since inputs and outputs are not electrically isolated from the processor.
To comply with CE Low Voltage Directives (LVD) and UL restrictions, you must use either a
Safety Extra Low Voltage (SELV), or a Protected Extra Low Voltage (PELV) power supply to
power this controller. A SELV supply cannot exceed 30V rms, 42.4V peak, or 60V DC under
normal conditions and under single-fault conditions. A PELV supply has the same rating and is
connected to protected earth.
IMPORTANT
IMPORTANT
The supply voltage is connected via a 4-pin connector that accommodates wire sizes up to
2
(14 AWG). You need to connect only one wire to L+ and one wire to L-. Both L+ and
2.5 mm
L- terminals are internally connected, so you can daisy-chain 24V DC power from the
GuardPLC controller to other devices in the panel by using the remaining terminal.
Protect the controller with a slow-blowing fuse.
The GuardPLC 1800 controller can draw up to 9 A. The controller needs 1 A to
operate. Up to 8 A can be used to source voltage power for inputs and
outputs connected to the controller.
ATTENTION: Do not reverse the L+ and L- terminals or damage to the
controller will result. There is no reverse polarity protection.

8 GuardPLC 1800 Controllers
The safe state of an input is indicated by a 0 signal being passed to the user program logic. If the
test routines detect a fault in the digital inputs, a 0 signal is processed in the user program for the
defective channel. When a fault occurs, the inputs are switched off (0).
Follow the closed-circuit principle for external wiring when connecting sensors. To create a safe
state in the event of a fault, the input signals revert to the de-energized state (0). The FAULT
status indicator activates.

LS+, not L+, should be used for short-circuit protection. Each LS+ features individual
short-circuit and EMC protection that make it important to use LS+ for only its eight related
inputs.
Line Control
The short-circuit and line break monitoring system, such as E-stop inputs, cannot be configured
for the GuardPLC 1800 controller. This is due to the fact that the 24 discrete inputs are actually
analog inputs with a resolution of one bit.
Safety-Related Analog Inputs
The controller has 8 analog inputs with transmitter supplies for the unipolar measurement of
voltages from 0…10V, referenced to L-. A 10 KΩ shunt is used for single-ended voltage signals.
With a 500 Ω shunt resistor, currents from 0…20 mA can also be measured.
The feeder lines should be no more than 300 m (984 ft) in length. Use shielded, twisted-pair
cables, with the shields connected at both ends, for each measurement input.
Unused analog inputs must be short-circuited. Place wire jumpers into any inputs that are not
used.

Connecting the I/O Circuits
The I/O circuits are connected to the front plate of the controller using pluggable terminals. For
controls with analog inputs, shielded cabling is fed in from below so that the shielding can be
connected to the shield contact plate using a clip. Remove about 2 cm (0.78 in.) of the outer
cable insulation so that the mesh is exposed at the point where the cable is clipped to the plate.
Position the clip over the uninsulated cable shielding and push it into the slots of the shield
contact plate until it fits firmly in place, as shown below.
Mesh
IMPORTANT
Shielded Cable
Make sure that the mesh comes in direct contact with the shield contact plate.
Cable Clip
If the mesh does not touch the plate, the cable is not grounded.
Safety-related Digital Outputs
The controller has eight digital outputs (DO1…DO8) whose status is indicated via status
indicators.
An output is in a safe state when it is de-energized. When a fault occurs, all outputs are switched
off.
Outputs 1…3 and 5…7 can have a load of 0.5 A at an ambient temperature of 60 °C (140 °F).
Outputs 4 and 8 can each have a load of 1 A at an ambient temperature of 60 °C (140 °F), or up
to 2 A at an ambient temperature of 50 °C (122 °F).
With an overload, one or all of the outputs are turned off. When the overload is eliminated, the
outputs are activated again according to the specified value.
Although the external line of an output is not monitored, a short-circuit will be indicated.

TIP
Inductive loads can be connected without a protection diode on the load.
However, Rockwell Automation strongly recommends that a protection diode be
fitted directly to the load to suppress any interference voltage. A 1N4004 diode
is recommended.
High-speed Counter Connections
The controller features two independent high-speed counters. Both counters are 24-bit, are
configured for either 5V or 24V DC, and have a maximum input frequency of 100 KHz.
The counters can be used as a counter or as a decoder for 3-bit Gray Code inputs. As a counter,
input A is the counter input, input B is the counter direction input, and input Z is used for a
reset.
The counter inputs must be connected using shielded, twisted-pair cables for each measurement
input. The shields must be connected at both ends. The input lines should be no more than
500 m (1640 ft) in length. All L- connections are internally connected on the controller.
Cables are clipped to the shield contact plate when connecting counter inputs. Remove about
2 cm (0.78 in.) of the outer cable insulation so that the mesh is exposed at the point where the
cable is clipped to the plate.
