UTC relay - Voltage monitoring & off delay
Informatie
Description
The time delay relay UTC incorporates also a voltage control function. The time delay is initiated by an impulse on the relay command which also closes the contact. The time delay relay can be initiated if the input voltage d0 is higher than the voltage control threshold. If the input voltage d0 is lower than the voltage control threshold, then the time delay is reset to 0, the contact is open and the relay is in the original state.
The contact is a solid state switch and is insulated of the part of relay control. The plug-in design offers secure locking feature for maximum ease of maintenance (no wires need to be disconnected or other hardware removed for relay inspection or replacement). The resistance to impact and vibration is conform to standards in force for Railway Transported Equipment.
Positive mechanical keying of relay to socket is built into relay and socket during manufacture and terminal identifications are clearly marked on identification plate that is permanently attached to the relay.
Application
The UTC relay is designed for voltage level sensing and used for example to monitor the battery load shedding.
