Product Description

Product Description

1. NPEXB-G512 supplies power to small power consumption intrinsically safe apparatus in hazardous area by controlling dry contacts, collector signal.

2. They are applicable to such intrinsically safe apparatus as solenoids and audible alarms. 

3. The input, output, and power supply, 3 terminals are galvanically isolated from each other. 

4. They have signal fault self-diagnosis function, and has the advantages of high reliability, quick response, and can be used with all kinds of instruments, DCS and PLC.
