Time Delay Relays

Time delay relays are a type of electronic control engineer relays, using magnetic and electronic technology to control circuits with specific timings, like, long duration timing cycles, repeat cycle timing, absolutely timing, etc. The SHS15M110A belongs in this category too.

Application Field

The SHS15M110A can be used for many different applications in an industrial setting, like:

• Lighting controls
• Motor control circuits
• Ventilation control
• Security systems
• Heavy duty machinery operations
• HVAC controls
• Food processing and preparation

The SHS15M110A provides very accurate delay time controls with a resolution up to 0.1s and useful for safety interlocking operations, controlling transformers, controlling the pressure of diesel engine air intake and controlling the speed of machineries.

Working Principle

The SHS15M110A uses a combination of electronic and magnetic technology to activate and deactivate its externally-attached control devices. A voltage or current signal is used to operate a miniature switch which acts as a trigger for the time delay circuit. When the signal is received, the time delay relay is activated. After the desired delay period, the output changes states and the activated relay deactivates. The delay times are adjustable, and can be set up to a maximum of 30 minutes.

The time delay is accomplished by using a series of different capacitor/resistor combinations and/or thyristors (specialized semiconductor devices) to produce a desired output voltage after the input signal is received. The voltage then remains constant for the duration of the delay period, and then a signal is produced to operate the relay.

The SHS15M110A has a robust and reliable design, ensuring that it can handle large surges of current and withstand operating temperatures up to 85°C. It also features overvoltage protection, overload and short circuit protection, as well as reverse voltage protection to ensure that the relay works perfectly even under harsh conditions.

The SHS15M110A is a great choice for any application where reliable and accurate time delay relays are needed. They are a cost-effective solution with multiple features and a rugged design for long-term use.
