The LM4A-2IO-M is an analogue and digital signals centralizer. In only 4 DIN modules, the unit has 2 relay outpus and centralizes 4 analogue inputs from 0 ... 20 mA, 2 voltage-free digital input. The unit includes an RS-485 communications bus with a Modbus/RTU protocol, which allows real time control by communications.
Monitoring of the 4 analogue inputs:yAnalogue signals from 0 ... 20 / 4 ... 20 mA
1024 points of resolution (10 Bits)yCompatible with any field probe with a 0 ... 20 mA output (Barometers, thermometers, manometers, anemometers, humidity probes, flow meters, digital wind direction indicators, lux meters, etc.)
