16 Channel 5V Mini-Relay Module BK_RL16_01

This is a 16 channel Mini-relay module. It can be used to control the lighting, electrical and other equipments. The modular design makes it easy to expand with the Arduino board or other MCU board PIC, ARM and MSP430. The Relay output state by a light-emitting diode. 

This module used HUIKE mini-relay and have ultra-small volume(be close to 8 channel Relay module). Maximum switching voltage: 120VAC 24VDC and Maximum switching current 2A. There are optocoupler as optical isolation to protect circuit security. 

At the same time, there is a elec-blocks socket, and you can use shunt cap directly to control the Relay module without MCU.
