DC Supervision Relay
E-Logics DC Supervision relay is used to supervise the DC supply. This relay is based on industrial standard smart microprocessor. The relay coil terminals are connected to the DC supply, which is to be monitored. In case, the DC auxiliary supply is available, the relay’s contact closes and healthy status is indicated through ‘Green’ flag. In the absence of the DC auxiliary supply, the same is indicated through ‘Red’ flag. To avoid the operation due to voltage dips \ sags, time delay is incorporated to give delayed drop off. It contains the four tripping contacts including Normally Open or Normally close status.
