- Optocoupler insulation: the 3V/3.3V 1-channel relay power switch module supports optocoupler isolation control. The design with the double power supply selection has strong anti-interference ability and high reliability of photoelectric insulation protection; the relay has a long service life and can be continuously activated 100,000 times.
- High-level trigger: the 1-channel relay power switch board is triggered by the high-level signal input of the microcontroller IO. It has an output signal indicator light; the signal input port can be connected to the IO port of the microcontroller and controlled by high-level signals.
- Bypass cap: By removing the jumper cap on the pin, you can freely choose whether relay and signal share the power supply. It is recommended to share a power supply to make it more convenient to use. The external wiring uses rotating crimp terminals to reinforce wiring; it has fixed mounting holes for easy installation.
- 30 VDC 250 VAC load: Equipped with a high current relay, AC250 V 10 A; DC 30 V 10 A, each relay has normally open and normally closed contacts. Selectable via jumper relay and TTL or ground.
- Product specifications: Built-in signal output indicator light, cable connection and mounting holes, compatible with 10A 250VAC and 10A 30VDC loads. Module size: 70mm x 17mm x 20mm / 2.76 x 0.70 x 0.79 inches.
- Free 30-Day Returns
- Full Refund for Damaged or Incorrect Items
- Guaranteed Delivery or Money Back
