IMPORTANT
For effective cooling, mount the controller following these guidelines.
• Mount the controller horizontally.
• Provide a gap of at least 100 mm (3.94 in.) above and below the controller.
• Select a location where air flows freely or use an additional fan.
• Do not mount the controller over a heating device.
The controller cannot be panel-mounted. Mount the controller to a DIN rail by following these
steps.
1. Hook the top slot over the DIN rail.
2. Insert a flathead screwdriver into the gap
between the housing and the latch and pull
the latch downward.
3. Hold the latch down as you push the housing
back onto the DIN rail.
4. Release the latch to lock the device onto the
rail.
TIP
To remove the controller from the DIN rail, insert a flathead screwdriver
into the gap between the housing and the latch and pull the latch

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 the DIN rail to the mounting surface approximately every
200 mm (7.8 in.) and use end-anchors appropriately.

Wire the Controller
The following sections 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
2.5 mm2 (14 AWG). You need to connect only one wire to L+ and one wire to L-. Both L+ and
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 1600 controller can draw up to 8 A. The controller needs 0.5 A
to operate. Up to 7.5 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.

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.

• a short-circuit occurs between two parallel connections.
• two connections are reversed.
• earth fault occurs on one of the lines (only with earthed reference pole).
• a line breaks or one of the contacts opens (that is, when one of the E-stop off switches is
pressed in the example above).
IMPORTANT
For information on how to configure inputs and outputs for line control, see
the GuardPLC Controller Systems User Manual, publication 1753-UM001
.
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.

The digital outputs can be pulsed with the safety-related digital inputs of the same device. This
enables short-circuit or line-break monitoring to be carried out (that is, emergency stop buttons
to conform to Cat. 4 in EN954-1).
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.
ATTENTION: Pulse outputs may not be used as safety-related outputs.
For more information on output wiring, see the GuardPLC Controller Systems
User Manual, publication 1753-UM001.
Make Communication Connections
The controller supports separate connections for safety and nonsafety-related communication.
Connections for Safety-related Communication
The controller has four 10/100BaseT, RJ45 connectors to provide communication via
GuardPLC Ethernet protocol to distributed I/O and other GuardPLC controllers, OLE for
Process Control (OPC) servers, and with the programming software. Connectors 1 and 2 are on
the bottom side on the left. Connectors 3 and 4 are on the top side on the left. All four
connectors and the GuardPLC processor are connected together by an internal Ethernet switch.
The switches are auto-detect. Either crossover or straight-through Ethernet cabling can be used.
Star or line configurations are available. Make sure that a network loop is not generated. Data
packets must be able to reach a node only via a single path.

Reset Push Button
The controller is equipped with a reset push button. Reset via the push button is necessary under
the following conditions.
• You forget the password to go online via the programming software.
• You are unable to determine the IP address and SRS of the controller.
The push button is accessible through a small round hole at the top of the housing,
approximately 4…5 cm (1.6…2.0 in.) from the left rim and recessed approximately 9.5 mm
(0.375 in.).
IMPORTANT
To reset, press and hold the push button for 20 seconds while rebooting the device by cycling
power. Pressing the Reset push button during operation has no affect.
With activation of the reset button:
Activate the reset push button using an insulated pin to prevent short-circuits.
• all accounts are deleted except for the default account.
• IP Address and System ID (SRS) are set to their default values.
The next time you cycle power, these settings will be restored to the last values stored into
nonvolatile memory. This means that either the settings prior to the reset will be restored, or if
any settings were changed after the reset, those new settings will still be in effect.
