This 16 channel relay module can be used to safely switch on and off 16 separate channels. This gives you control over other circuits or devices, without the risk of the arduino being damaged or dangerous situations arising. The relays switch single-pole, which means that only the + or - of a circuit is switched.Properties:
- Operates on 5V
- Every input needs 15-20mA Driver Current
- Switches maximum AC250V 10A; DC30V 10A
- An indication LED for each channel.
