function

Beijiafu P+F safety barrierThis isolation barrier is used for intrinsically safe explosion-proof applications.

This device transmits digital signals from NAMUR sensors or dry contacts in hazardous areas to non hazardous areas.

Control side load of relay contact output controlled by proximity sensors or mechanical contacts. When the input signal state changes, the device output state changes accordingly.

The working mode can be reversed and the line fault detection can be turned off through the switch.

In the fault state, the relay returns to the power-off state, and the LED indicator light indicates the fault according to NAMUR NE 44 standard.

If the device is powered through a power rail, it will also provide a centralized error message.

Due to its compact housing design and low heat generation, this device is suitable for position, limit, and switch status detection in space constrained applications.
