The TSDR442MA2 is a recycling time delay relay with a fixed 2-minute OFF time and an adjustable 10 to 100-second ON time, designed for industrial applications requiring compact, solid-state timing control. It operates on 120VAC with a tolerance of ±20%, consumes ≤2VA, and drives a 1A steady, 10A inrush solid-state output. The module measures 50.8 mm × 50.8 mm × 30.7 mm and mounts via a single #10 screw. Time delay accuracy is ±5% factory calibrated and ±0.5% repeat accuracy, with operation over -40°C to 75°C. The circuitry is encapsulated for protection against shock, vibration, and humidity, and termination uses 0.25 in. (6.35 mm) male quick-connect terminals.
The TSDR Series is an ON/OFF or OFF/ON recycling timing module designed to control metering pumps, chemical valves, flash lamps, or use in energy saving or duty cycling applications. It may be ordered with both time delays factory fixed, or one delay fixed and the other delay external or onboard adjustable. The TSDR 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 < ±5%. The repeat accuracy, under stable conditions, is 0.5% of the time delay. The TSDR 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 (Recycling - ON Time First)Upon application of input voltage, the output energizes and the T1, ON time begins. At the end of the ON time, the output de-energizes and the T2, OFF time begins. At the end of the OFF time, the output energizes and the cycle repeats as long as input voltage is applied.Reset: Removing input voltage resets the output and time delays, and returns the sequence to the T1 ON time. Operation (Recycling - OFF Time First)Upon application of input voltage, the T2 OFF time begins. At the end of the OFF time, the T1 ON time begins and the load energizes. At the end of the T1, T2 begins and the load de-energizes. This cycle repeats until input voltage is removed.Reset: Removing input voltage resets the output and the sequence to T2 OFF time.
