1-Channel Opto-Isolated Mechanical Relay (A041)

BIT-TREE 1-channel opto-isolated relay module adopts Omron G2R-2 mechanical relay. It achieves strong & weak electrical isolation via optocoupler, works under 5V control voltage, supports trigger switching with high/low logic levels. Contact load rating reaches 5A/230VAC, widely applied to home appliance control, high-power switching, smart security and other engineering projects.

   Built-in optocoupler realizes complete electrical isolation between control side and load side, blocks surge, noise and reverse current transmission, effectively protects main control circuit, greatly

   Supports both high-level and low-level trigger modes, you can switch trigger logic flexibly according to MCU /single-chip microcontroller output characteristics, compatible with diverse control hardwa

   Equipped with premium Omron mechanical relay contacts, it can sustain 5A 230VAC large alternating current load. Excellent contact wear resistance guarantees stable long-term operation for frequent on-
