THIS IS A 12V 8-CHANNEL OPTICAL ISOLATED RELAY INTERFACE BOARD, BE ABLE TO CONTROL VARIOUS APPLIANCES, AND OTHER EQUIPMENTS WITH LARGE CURRENT. IT CAN BE CONTROLLED DIRECTLY BY MICRO-CONTROLLER, HOME ALARM SYSTEM.
12V 8-Channel Relay interface board, and each one needs 15-20mA Driver Current & 5mA trigger current
Equiped with high-current relay, AC250V 10A ; DC30V 10A
Fault-tolerant design, even if the control line is broken, the relay will not trigger accidently
Standard interface that can be controlled directly by microcontroller & Alarm system
Full screw terminal for ease installation & secure connection
Indication LED’s for Relay output status (Red color) & Power (Green color)
High / Low input signal trigger selection by jumper. Support NPN / PNP PLC extension / Selectable Positive / negative trigger signal.
Dual side printed FR-4 PCB for Stable high current as in specification
Manufacturer under IPC-610 standard for stable & durable
