I-AUTOC Single Phase Solid State Relay, 20A, 32V DC Coil

The I-AUTOC Single Phase Solid State Relay is a high-performance, zero-crossing switching device designed for robust industrial control applications. Featuring a solid-state SCR (Silicon Controlled Rectifier) output, it ensures reliable, silent operation with no moving parts, offering a long operational life and high resistance to shock and vibration.

This relay boasts a high dielectric strength of 4000Vrms, providing excellent isolation and protection for sensitive control circuits from high-voltage transients on the load side. The integrated 30mm wide heatsink allows for efficient thermal management, enabling the relay to handle its full 20A load current rating consistently. A clear LED indicator provides instant visual confirmation of the load status, simplifying system monitoring and troubleshooting.

Designed for flexible installation, it is compatible with 35mm DIN rail mounting or can be directly panel-mounted, making it suitable for a wide range of enclosures and control panels. The zero-crossing switching mode minimises electrical noise and inrush current, protecting connected loads such as heaters, transformers, and motors. With a wide control voltage range of 4 to 32V DC, it offers excellent compatibility with PLCs, microcontrollers, and other standard industrial control voltages.
