Channel 3
1
The input delay applies to "0" to "1" and to "1" to "0".
2
Short circuit of the sensor supply.
3
Can only be assigned parameters for the IM151-1 High Feature interface module and the IM151-7 CPU
4
If the wire break check is activated, all the unused inputs must be stabilized to prevent them from triggering a module
wire break. To do this, connect a resistor between terminal 24/48 V (3, A4, 7, A8) and the free input. The resistor must
provide at least 0.5 mA of input current (see "Sensor Switching" in the table of technical specifications). This ensures that
sufficient current is flowing to prevent wire break detection.
The sensor must supply at least 0.5 mA when switched off (otherwise wire break will be detected when switched off).
Alternatively, a resistor can be connected parallel to the sensor terminals (the current must be at least 0.5 mA).
