Chapter 5   Safety Module Features
The following apply to the safety inputs:
• You can connect safety devices, such as Emergency Stop Push Button, 
gate switches, and safety light curtains.
• Evaluate an input signal, that is, input data, in single-channel mode or 
dual-channel mode.
• An external wiring short circuit check is possible when inputs are wired 
in combination with test outputs. The module must be wired in 
combination with test outputs when this function is used.
• Independently adjustable on and off delays are available per channel.
The following apply to the test standard outputs:
• Separate test outputs are provided for short circuit detection of a safety 
input (or inputs).
• Can supply 24V DC power to devices, such as safety sensors.
• As many as two specific test outputs can be used for broken-wire 
detection of a muting lamp.
