32 digital inputs
6ES5 430-4UA12
Digital inputs can be used to import status signals
into the chromatograph. Example: carrier gas
pressure monitoring.
The signal status of the digital inputs is identified by
green lamps on the module.
Connection of switches
Connect one line directly to the front plug of the mo-
dule, and the return line to the central +24 V terminal
block.
