2 Channel isolated barrier
Description

Informationen zu diesem Produkt

Hier ist alles, was Sie wissen müssen

The KFD2-SR2-EX2.W is a 2 channel isolated barrier is used for intrinsic safety application. It is prime use is to transfer digital signals (NAMUR sensors/mechanical contacts) from a safe area to a hazadous area. The proximity sensor or switch controls a form C change over relay for the safe area load. The normal output state can be reversed using switches S1 and S2. Switch S3 is used to enable or disable line fault detection of the field circuit.

During an error condition, the relays revet to their de-engergized state and the LEDs indicate the fault according to NAMUR NE44. A unique collective error messaging feature is available when used with the power rail system
