SAS180S12AD Industrial Controls

Time Delay Relays are an important element in electric control circuits. They are used in industrial electronics, military and industrial automation systems and consumer electronic equipment. The SAS180S12AD Time Delay Relay is a specially designed device for use in applications such as circuit protection, delayed shutdown and high current switching or indicate multiple time delays. The unit is designed to switch or control loads with a switched voltage of up to 250Vrms/250Vdc with a current rating of 15A.

Application Field

Time Delay Relays are widely used for time delayed switching, circuit protection, measurement and control. For the SAS180S12AD, the primary application is to enable a signal to be supplied at a desired time in order to switch other electric loads when the signal arrives. The delay of the SAS180S12AD can be adjusted from 0.1 to 1 second.

The SAS180S12AD is an ideal device for applications requiring delayed switching and control, such as:

• Commercial equipment
• Industrial equipment
• Timed lighting control
• Security systems and alarms

Working Principle

The basic operation of the SAS180S12AD is the same as an ordinary relay, but with a time delay feature. The time delay feature is implemented by the integrated circuit, which contains an oscillator that generates a voltage pulse. The duration of the pulse is determined by the adjustable potentiometer on the circuit board. The output of the pulse is applied to the coil, which then triggers the relay switch.

The SAS180S12AD uses a bimetallic strip which is heated by the current passing through it. When the temperature of the strip reaches the specified limit, the contacts of the relay will open or close. The adjustable time delay potentiometer can be set to increase the delay time or decrease it, depending on the required application.

Conclusion

The SAS180S12AD is a versatile and cost effective Time Delay Relay for a wide range of applications. It combines the reliability of a mechanical relay with the accuracy and precision of an integrated circuit, allowing for precise time delay control. The unit is easy to install and provides a reliable solution to many applications needing a time delay feature.
