Promake Relay 2CH
Description
The ProMake Relay 2CH is a dual Channel relay board, which can be operated by the host MCU or Processor. This Module is an easy solution for controlling a wide range of high power AC or DC loads like small home appliances, electro-motors or switching on the lights. The Module uses two G5NB-1A-E-DC5V mini-relays, from Omron.
Features
- Can switch loads of up to 250 VAC or 30 VDC
- Operates with 5V control signal.
- Maximum Current capacity of 3A
- Transistor-based control, minimizing the current that needs to be provided by the microcontroller pin.
- LED indication of Relay State
- Breadboard-friendly
Important Notes
- CAUTION: only connect this module directly to AC grid power if you already have prior experience with AC circuits. Misuse of this module might cause ELECTRIC SHOCK and FIRE.
