3RT1926-2DH21 SIEMENS

The 3RT1926-2DH21 is an electronic timing relay from Siemens, designed to provide precise time-delayed switching functions in industrial control applications. This relay features a semiconductor output, ensuring reliable and long-lasting performance. It offers a time range of 0.5 to 10 seconds, adjustable to suit various timing requirements. The relay operates on a wide AC/DC voltage range of 90 to 240 V, providing flexibility in different power supply environments. It is configured for OFF delay operation, meaning the output is energized when the input signal is applied and de-energizes after the set time delay upon removal of the input signal. An integrated varistor provides surge protection, enhancing the relay's durability and protecting it from voltage spikes. The relay utilizes screw terminals for secure and easy wiring. It is designed for direct mounting onto contactors of sizes S0 to S3, simplifying installation and saving space in control panels. This timing relay is ideal for applications requiring accurate and dependable time-delayed switching, such as motor control, lighting control, and process automation.
