SKU: N/A

Analog input modules record process signals such as pressure or temperature and forward them in digitalized format (16-bit format) to the PLC. They are suitable for measuring current (2-wire and 4-wire transducers), voltage, and resistance, as well as for the connection of resistance thermometers and thermocouples (measurement types depend on the module).
