CONSTRUCTION AND OPERATION

The Seal - In Relay is basically composed of:

1- Standard box DIN 10-10

2- Pulsing rearming button

3- Two contact relay with NANF outlet

4- LED for operation signaling

The Seal - In Relay function is to actuate, from an external command remaining so until it is manually rearmed by means of a button installed on the front of the relay. The Relay can only be rearmed if the reason for its disarming has been eliminated. It has a signaling LED for the latched position; and two independent reversible contacts for alarm or disconnection.
