Description
The Littelfuse CT1S90 On/Off Time Delay Relay controls the timing of circuit activation and deactivation by introducing a programmed part between the signal and the switching action, preventing immediate response to input changes that could cause short cycling or premature component activation. Its internal timing circuit holds the output contact open or closed for the set delay period after receiving the input signal, ensuring the connected load activates, or deactivates only after the programmed interval has elapsed. It connects within HVAC systems at the control circuit terminals using standard relay sockets or direct wire connections.
