Product Description

Product Description

 

<1>. NPEXA-G511 safety barrier transfers digital signals (NAMUR sensors/mechanical contacts) from a hazardous area to safe area, with the relay output or open collector output, free choice to acting or reacting function.

<2>. The input, output, and power supply, 3 terminals are galvanically isolated from each other. 

<3>. It has signal fault self-diagnosis function, and has the advantages of high reliability, quick response and so on. It can be used with all kinds of instruments, DCS and PLC.
