Precautions for wiring the safety remote I/O module to safety
devices
This section describes the precautions for the wiring. To wire the safety remote I/O module to each safety device according to
Category 4, perform both of the following for the safety remote I/O module.
• Double wiring inputs/outputs
• Executing the self-diagnostic function (dark test)
When performing the operations above, observe the precautions below.
When wiring the input part
■Combination of input terminals
The following table lists the applicable combinations of input terminals. If the combinations other than the below are used, a
minor error occurs.
• NZ2GFSS2-32D-S1
• NZ2GFSS2-8D-S1, NZ2GFSS2-16DTE-S1
■Test pulse output terminal combination
The same test pulse cannot be used for the combinations for one device. If the combinations of the same test pulse are used
for one device (X0 and T0, X1 and T0 for instance), a minor error occurs.
When wiring the output part
■Combination of output terminals
The following table lists the applicable combinations of output terminals. If the combinations other than the below are used, a
minor error occurs.
