8 Channel Relay Module 5V with Optocoupler

8 Channel Relay Module 5V with Optocoupler Can be used as microcontroller development board module can be used as home appliance control 5 V-12V to TTL control signal The control signal DC or AC, 220V AC load can be controlled. There is a normally open and one normally closed contact A power indicator light A control indicator, pull off, disconnect does not shine Transistor drive to increase the relay coil control pins high impedance. The control pin has a pull-down circuit to prevent malfunction relay vacantly Specifications:-  Maximum load: AC 250V/10A, DC 30V/10A Trigger current: 5mA Working voltage: 5V Module size: 50 x 26 x 18.5mm (L x W x H) Four mounting bolts holes, diameter 3.1mm DC : positive power supply (VCC) DC-: negative power supply (GND) IN: can be high or low level control relay NO: normally open relay interface COM: Common Interface Relays NC: normally closed relay interface It is low level trigger when jumper connect to LOW pin It is high level trigger when jumper connect to HIGH pin   SKU: CE-M0181 Categories: IoT & Wireless, Modules & Sensors Tags: 8 channel, re*.*, Realy, Realy module, Relay, relay module
