RCM222

The RCM222 is used to measure analog voltages and to output control voltages
 in the range of 0-10 V.This enables him to query and control electronic devices
 and sensors with a 0-10 V interface.The device has an Ethernet and an RS485 interface
 for connection to e.g. PC / process control system / Arduino or similar.
