Function: M-LB-5400

The fault status module indicates that a fault has occurred on one of the monitored protection modules.

The status indication is transmitted to the control via the status indication output. The status indication output is performed via a solid state relay.

The device switches if a fault is detected on one of the monitored protection modules.

The device has LEDs for indicating supply and fault.

The device is plugged onto the base module and, together with the base module, forms the evaluation unit.

The device can be replaced without tools by a locking lever.
