Product Description

The RPR 415 relay is a directionally controlled timing relay used to protect AC generators from motoring. When such a condition occurs and the reverse current exceeded the customer adjustable preset limit and the current persists for a predetermined delay time, the trip relay operates to diconnect the circuit.

Product Description

Alarm relay provides LED indication and output

contact signalling when there is alarm signal

received. The alarm relay consist of alarm input,

alarm accept, alarm reset, lamp test controlled

input and 2 relay contacts. Red LED indication

2 (LED) turned on when alarm signal is received.
