INFICON LDS3000 Modular Leak Detector - Manual (Page 27)

Operation 27
6.3 Assigning the digital inputs of the I/O module
The available functions can be assigned in any way necessary to the digital inputs
PLC-IN 1 ... 10 of the I/O module.
Active signal: typically 24 V; inactive signal: typically 0 V.
The 24V output of the I/O module can be used as an active signal.
