16CH 16 Channel 5V Mini Relay Module for Arduino PIC ARM AVR MSP430

16CH 16 Channel 5V Mini Relay Module for Arduino PIC ARM AVR MSP430


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 was 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 and protect circuit security.

At same time, there has elec-blocks socket, and you can use shunt cap direct control the Relay module without MCU.

Specifications:
- Drive current: 20mA
- Drive voltage: 5V
- Optocoupler,more secure
- LED Power supply indicator, Channel LED indicator
- Control signal: 5V TTL level
- Maximum switching voltage: 150VAC 24VDC
- Maximum switching current: 2A
- PCB Color: White
- Positioning holes: 3mm
- Dimension: 85mm*72mm
