The MSM210P3 is a solid-state delay-on-make timer designed for printed circuit board mounting, with a fixed 10-second time delay and 24VAC input. It features no moving parts, immediate reset upon power removal, and is fully encapsulated for protection against shock, vibration, and humidity. The output is a normally open solid-state contact with a maximum load current of 0.5A at 25°C and 0.25A at 60°C, and a voltage drop of approximately 2.5V at 0.5A. Its dimensions are compact, with a wire length of 0.5 inches (12.7 mm) for PCB mounting. It operates within a temperature range of -20°C to 60°C and is protected against reverse polarity. The time delay accuracy is ±5% with a factory calibration tolerance of ±15%.
The MSM replaces bi-metal type timing with reliable solid-state circuitry. There are no moving parts to arc or wear. It is a cost effective solution for OEM designers. It is available for printed circuit board mounting or surface mounting with a removable bracket and wire leads. The MSM offers immediate reset on removal of power. Operation (Delay-on-Make)The time delay begins upon application of input voltage. The output is de-energized before and during the time delay. At the end of the time delay, the output energizes and remains energized until input voltage is removed.Reset: Removing input voltage resets the time delay and output.
