Intrinsic safety & signal conditioning

Power feed module


For use with KFD2 20mm barrier units only

The power feed module interfaces 24V d.c. power to the Power Rail at a maximum current of 4A. The twin input terminals allow for daisy-chaining of supply (max. 10A).

A green LED on the front of the unit indicates that power is on, and a red LED illuminates during error conditions. In the event of a field wiring or barrier fault from any barrier on the Power Rail, the integral collective error messaging relay alerts the controller via a single discrete I/O point.

This relay can be configured as normally open or normally closed.

In the sense of functional safety (SIL) the device provides no dangerous failures. Thereby the safe condition of the supplied barrier must be defined as the powerless state. The device will not influence the safety calculation or the SIL value.

This device is compatible with all versions of the Power Rail.
