I-AUTOC Single Phase Solid State Relay, Zero Crossing, 240V AC 20A

The I-AUTOC Single Phase Solid State Relay provides a highly reliable and efficient switching solution for a wide range of industrial and commercial applications. Engineered for panel or DIN rail mounting, this relay features a robust SCR (Silicon Controlled Rectifier) output and is designed with a zero-crossing switching mode. This ensures smooth, low-noise operation by switching the load precisely when the AC voltage waveform crosses zero, minimising electrical stress and electromagnetic interference.

This model is built to handle a maximum load current of 20A and an operating voltage of up to 240V AC, making it suitable for controlling motors, heaters, and lighting systems. The unit incorporates a compact, 30mm wide integrated heatsink for effective thermal management, promoting long-term stability and preventing overheating during continuous operation. A clear LED indicator provides instant visual confirmation of the load status, facilitating easy system monitoring and troubleshooting.

With a high dielectric strength of 4000Vrms, it offers excellent insulation and protection against voltage spikes, enhancing the safety and durability of your electrical setup. Its versatile mounting options include standard 35mm DIN rail installation or direct panel mounting, allowing for flexible integration into control cabinets and electrical enclosures. The relay accepts a wide control voltage range from 0 to 280V, ensuring compatibility with various control signals and logic levels.

Constructed from high-quality materials, this solid-state relay delivers silent, maintenance-free operation with a fast switching speed and a long operational lifespan, far exceeding that of traditional electromechanical relays. It is an essential component for modern automation, process control, and power management systems where precision and reliability are paramount.
