Wire the Module
The following sections describe how to wire the module.
Ground the Module
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 number
1770-4.1.
The I/O module is functionally grounded through its DIN rail connection. A
protective earth ground connection is required and is provided through a separate
grounding screw, located on the upper left of the housing and marked with the
grounding symbol .
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 (e.g. aluminum,
plastic, etc.) that can corrode, oxidize, or are poor conductors,
can result in improper or intermittent grounding.
Connections for Safety-Related Communications
Ethernet Switch
The module has two 10/100BaseT, RJ-45 connectors to provide communications to
the GuardPLC controller via GuardPLC Ethernet. The connectors are located on the
bottom side on the left. The connectors and the module are connected together by
an internal Ethernet switch. The switches are auto-detect. Either cross-over or
straight-through shielded Ethernet cabling can be used.
Star or line configurations are available. Make sure that a network loop is not
generated. Data packets must only be able to reach a node via a single path.
MAC Address
The Media Access Control (MAC) Address of the module can be found on the label
positioned over both lower RJ-45 connections.

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. In order to comply with CE Low Voltage Directives (LVD), you must use
either a NEC Class 2, a Safety Extra Low Voltage (SELV) or a Protected Extra Low
Voltage (PELV) power supply to power this adapter. An SELV supply can’t 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
The supply voltage is connected via a 4-pin connector. See page 18 for the
appropriate wire size. You only need to connect 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 module to other devices in the panel using the remaining terminal.
ATTENTION
Protect the module with a 10 A slow-blow fuse.
Do not reverse the L+ and L- terminals or damage to the module
will result. There is no reverse polarity protection.

The safety 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) and the fault LED indicator is activated.
Follow the closed-circuit principle for external wiring when connecting sensors. To
create a safety state in the event of a fault, the input signals revert to the
de-energized state (0). Although the external line is not monitored, a wire break is
interpreted as a safe 0-signal.
TIP
For more information on input wiring, see the GuardPLC
System User Manual, publication number 1753-UM001.

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 it’s four
related inputs.
Surge on Digital Inputs
An EN 61000-4.5 surge impulse can be read as a short-time HI signal. To avoid an
error:
• install shielded input lines to prevent effects of surges in the system, or
• implement software filtering in the user program. A signal must be present
for at least two cycles before it is used by the rest of the logic in the user
program.

When line control detects any of the following faults, inputs are set to 0, a fault
code is generated, and the FAULT LED indicator is on.
• short-circuit between two parallel connections
• reversal of two connections
• earth fault on one of the lines (only with earthed reference pole)
• line break or opening of the contacts (e.g., when one of the E-stop off
switches is pressed in the example above), the FAULT LED indicator is on
and the fault code is generated.
IMPORTANT
For information on how to configure inputs and outputs for line
control, see the GuardPLC System User Manual, publication
number 1753-UM001.
Safety-Related Digital Outputs
The module has 8 positive-switching digital outputs that switch 24V dc and two
negative-switching digital outputs that switch 24V com whose status is indicated via
LED indicators.
The positive and negative-switching digital outputs can be connected in a one-pole
or two-pole manner.
If configured for one-pole operation, use the reference pole L- for the
positive-switching outputs and reference pole S+ for the negative-switching
outputs. The total output current of the module is limited to 8 A and is generated
from the 24V of the system.
If configured for two-pole operation, the positive-switching output DO4 operates
with the negative-switching output DO4- and the positive-switching output DO8
operates with the negative-switching output DO8-. Line control is carried out for
detection of an external short-circuit between positive and negative-switching
outputs. A switch-on delay is necessary for inductive or capacitive load or lamp
load since the inrush of these loads may be mistakenly detected as a short-circuit.
This delay is set in the RSLogix Guard PLUS! Hardware Management via the
Switch-on delay signal at the negative-switching output variables. The delay can
be set from 0 to 30 ms, in 1 ms increments. An external line break will not be
detected.
An output is in a safety state when it is de-energized. When a fault occurs, all
outputs are switched off.
Outputs 1 to 3 and 5 to 7 can have a load of 0.5 A. Outputs 4 and 8 can each have
a load of 1 A at the maximum ambient temperature 60 °C (140 °F), 2 A at an
ambient temperature of 40 °C (104 °F).
Publication 1753-IN010A-EN-P - October 2005
Page 14
14 GuardPLC 8-Digital Inputs and 8-Digital Outputs Module
The negative-switching outputs DO4- and DO8- can supply up to 1 A at the
maximum ambient temperature of 60 °C (140 ° F), 2 A at an ambient temperature of
40 °C (104 °F).
With an overload, one or all of the outputs are turned off. When the overload is
eliminated, the outputs are activated again.

For connection of a load, the reference pole L- of the channel group must be used.
Although L- at terminals 7 and 12 and at terminals 13 and 18 are connected
internally to L- on the power supply input, it is strictly recommended to use 7 and
12 for outputs 1 through 4 only and 13 and 18 for outputs 5 through 8 only. EMC
testing was performed in this manner.
