ITEM NAME:8-Channel 8-CH Relay Module DC 5V with Optocoupler isolation H/L high/low L K6N2 8-Channel 8-CH Relay Module DC 5V with Optocoupler isolation H/L high/low L K6N2 the module uses genuine quality relay, normally open interfaces Maximum load: AC 250V/10A, DC 30V/10A; using SMD optocoupler isolation, driving ability, stable performance; trigger current 5mA; the module Operating voltage 12V; the module can be high or low by a jumper setting trigger; fault-tolerant design, even if the control line is broken, the relay will not operate; the power indicator (green), the relay status indicator (red)the interface design of human nature, all interfaces are available through a direct connection terminal leads, very convenient Module interface: 1. DC+: positive power supply (VCC) 2. DC-: negative power supply (GND) 3. IN1,2,3,4,5,6,7,8: can be high or low level control relay S1,S2,S3,S4, S5,S6,S7,S8 HIGHT OR LOW LEVER Relay outputs: 1. NO1,2,3,4,5,6,7,8: normally open relay interface 2. COM1,2,3,4,5,6,7,8: Common Interface Relays 3. NC1,2,3,4,5,6,7,8: normally closed relay interface High and low level trigger options: It is low level trigger when jumper connect to LOW pin It is high level trigger when jumper connect to HIGH pin colour: Photo Color Material: plastic size: 141.5mm * 50mm * 18.5mm Package Contents: 1*5V 8CH relay module.Using SMD optocoupler isolation, driving ability, stable performance; trigger current 5mA;. the module uses genuine quality relay, normally open interfaces Maximum load: AC 250V/10A, DC 30V/10A;. 1 5V 8CH relay module.
