Time Delay Relays Dedicated - Delay-on-Break TSDB SERIES Description The TSDB Series is designed for more demanding commercial and industrial applications where small size, and accurate performance are required. The factory calibration for fixed time delays is within 1% of the target time delay. The repeat accuracy, under stable conditions, is 0.5% of the time delay. The TSDB Series is rated to operate over an extended temperature range. Time delays of 0.1 seconds to 1000 minutes are available. The output is rated 1A steady and 10A inrush. The modules are totally solid state and encapsulated to protect the electronic circuitry. Operation (Delay-on-Break) Input voltage must be applied before and during timing. Upon closure of the initiate switch, the output energizes. The time delay begins when the initiate switch is opened. The output remains energized during timing. At the end of the time delay, Wiring Diagram the output de-energizes. The output will energize if the initiate (Positive Switching) switch is closed when input voltage is applied. L1 N/L2 Reset: Reclosing the initiate switch during timing resets the time delay. Loss of input voltage resets the time delay and output.
