The power feed module supplies the Power Rail with a voltage of 24 V DC and a maximum current of 4 A. The device is designed for applications requiring redundant power.
In the event of a device fault or a wiring fault of any isolator on the Power Rail, the collective error messaging relay alerts the controller via a binary I/O point. This relay can be configured as normally-open or normally-closed.
A green LED on the front of the device indicates the power state, and a red LED lights up during a fault condition.
Additionally, the bus implemented in the Power Rail is forwarded to the terminals 13 and 15 for usage with the RS-485 connection of the KFD2-WAC2-Ex1.D device. Terminal 14 is only for test purposes.
In the sense of functional safety (SIL) the device provides no dangerous failures. Thereby the safe condition of the supplied isolators must be defined as the de-energized state. Thus the device will not influence the safety calculation or the SIL value.
This device is compatible with all versions of the Power Rail and provides group fusing.
Note: Redundant systems require 2 KFD2-EB.R4A.B power feed modules.
