Function description
4.1
Module and periphery supply
Module supply
}
The module supply provides the module with voltage.
Periphery supply
}
The periphery supply that supplies the outputs must be fed externally. The single-pole
outputs must have a common supply voltage.
4.2
FS outputs
4.2.1
Single-pole outputs
}
2 single-pole digital outputs
Output test
}
Outputs that are switched on are checked via regular off tests.
– Test pulses for outputs that are switched on: see
– Outputs that are switched on are switched off for the duration of the test pulse.
– The load must not switch off because of the test.

Outputs that are switched off are checked via regular on tests.
– Test pulses for outputs that are switched off: see
– Outputs that are switched off are switched on for the duration of the test pulse.
– The load must not switch on because of the test.
Excluding individual outputs from the output test:
}
If a plant is particularly sensitive to the test pulses, the output test may be switched off for
individual outputs.
}
The test must be replaced by other measures, depending on the safety requirement.
}
When test pulses are switched off:
– The correct switch status is always checked.
– The output's ability to switch will not be detected until the next time the output is
switched on/off.
