CS195: Current Loop Supply (Isolate)

- Powers 2 wire transmitter

- Intrinsically saft without barriers or safety


- Output 4-20mA, 1-5V, 0-10V

- DIN rail mounting


            The Current Loop Supply CS195 provides a floting DC supply for energizing a 2-wire transmitter in a hazardous area,and repeats the transmitter signal in another floating circuit to drive a safe-area load. The unit is intrinsically saft for connection to Zone 0,1 or 2 hazardous-area wiring, dose not require the use of safty barriers and dispenses with the need for isolation in transmitters used with earthed or poorly insulated sensors.
