ELX4154 | 4-channel analog output terminal 0/4…20 mA, single-ended, 16 bit, Ex i

The ELX4154 analog output terminal is used for the direct connection of intrinsically safe field devices located in hazardous areas classified Zone 0/20 or 1/21. It can be used, for example, to control intrinsically safe controllers for control valves. The output current range can be switched between 0…20 mA and 4…20 mA. The ELX4154 is supplied via the power contacts of the ELX9560 power supply terminal.
