The MSM25W9 is a delay-on-make time delay relay with 24VAC input, a fixed 5-second delay, and standard wire leads 9.0 inches (228.6 mm) long. It uses solid-state circuitry with no moving parts, offering immediate reset upon power removal. The relay has a normally open output that energizes after the delay and can handle a maximum load current of 0.5A at 25°C or 0.25A at 60°C. It is encapsulated for protection against shock, vibration, and humidity, and supports mounting with a removable bracket. Operating temperature ranges from -20°C to 60°C, with storage from -30°C to 85°C. Repeat accuracy is ±5%, with ±15% tolerance from factory calibration.
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.
