The SSRP electronic relay is an electronic module with a built-in power triac controlled at the “zero” point and is designed to switch single-phase AC active or small inductive loads from 10 A to 40 A at voltages up to 275 VAC. Thanks to the high commutation frequency and the complete absence of noise and electromagnetic emissions, the SSR module is a modern contactless replacement for electromechanical relays and contactors. Its life and reliability are greater than those of electromechanical relays due to the absence of moving parts, vibration and contact wear. The control signal is optically separated from the output and can be constant or variable voltage, the presence of which is monitored by a special indicator.
