# MSM Series Time Delay Relays

## Description
️· Replaces bi-metal timing with solid-state circuitry.
️· Offers immediate reset on power removal.
️· Available for PCB mounting or with wire leads.
️· Cost-effective for OEM applications.

## Operation (Delay-on-Make)
️· Output de-energized before and during time delay.
️· Output energizes at end of delay and remains energized until input voltage is removed.
️· Reset occurs upon removal of input voltage.

## Features & Benefits
️· Analog Circuitry: Repeat Accuracy ±5%, Factory Calibration ±15%
️· Compact Design: Allows OEM flexibility.
️· Long Life: No moving parts.
️· PCB/Wire Harness: Offers design/installation flexibility.
️· Immediate Reset: Occurs on power removal.
️· Encapsulated: Protects against shock, vibration, and humidity.
