Product Description

Product Description

<1>. NPEXB-GM31 isolated safety barrier transmits current signals from safe area to hazardous area by isolating and transmitting current or voltage signals.

<2>. It can control electric transducer,valve positioner and other field apparatus.

<3>. Input, output and power supply, 3 terminals are galvanically isolated from each other, own the advantages of low power consumption and quick response.
