This 16 Channel Relay Module consists of sixteen 12V relays and each one of the individual relays needs 15-20mA driver current. This module has coupling protection (optocoupler) which provides opto-isolation for safety purposes. This is a Relay module of 16 channel interface board that can be control various appliances, and other electronic equipment with a large current. It can be controlled by Micro-controllers like Arduino, Raspberry-pi, ARM, TTL logic directly.
 
Specifications:
12V relay with AC contact capacity of 10A 250V and optocoupler protection.
Onboard power supply module, doesn't need any external power supply.
The module can be used as a microcontroller development board module and also as appliance control, PLC extended output.
It is using the industry’s top-quality isolation optocouplers, strong anti-jamming ability, stable performance.
The 1-16 road can be any full on/off or any road.
All interfaces can be directly connected through the terminal leads, very convenient.
Indication LED’s for Relay output status
