Description

The SSRD electronic relay is an electronic module with a built-in power transistor and is designed to switch direct current active or active-inductive loads with a maximum current of 5 A to 40 A at a voltage of up to 300 VDC. 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.
