Time Delay Relays are electronic components used to introduce a delay into an electrical circuit. They allow a circuit to remain closed for a specified duration and then open or close at a predetermined time. SHSP20M220A is a type of time delay relay which provides the user with a wide choice of preset delay timing.

The SHSP20M220A is suitable for a wide variety of applications, including delaying the operations of motors, lights, compressors, exhaust fans, switches, and other electronic equipment. It can also be used in machine start/stop control and in data acquisition system applications. In addition, it is well-suited for applications involving sequencing, switching, and control.

The SHSP20M220A features two independent SPDT relays with separate time delays; one relay operated with a nominal delay of 0.5 to 20 seconds and the other with a nominal delay range of 0.2 to 2.0 minutes. Both relays are triggered by switch closures that activate a voltage-controlled oscillator (VCO) via a current-driven circuit. The VCO controls the duration of the closure of the relay contact and also the opening of the contact.

The SHSP20M220A also has hysteresis control which allows the circuit to remain stable in the absence of noise and/or temperature variations. There is also a programmable booster output which can be set to mimic the time delay of the two relays via an electronic current sensor. This boosts the output voltage, which can then be used to power other components in the system, such as LCD displays, clocks, and alarms.

The SHSP20M220A is an ideal choice for applications where precise time delays are necessary. With its wide range of preset delay timing, hysteresis control, and programmable booster output, it is able to meet the needs of any number of applications where precision timing is required.
