ITEM NAME:1 Channel Optocoupler High/Low Level Relay Module 5V DC for ARM DSP AVR H8B7 1 Channel Optocoupler High/Low Level Relay Module 5V DC for ARM DSP AVR H8B7 1 Channel Module description: 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 5V; 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 size: 50mm*26mm*18.5mm (L*W*H) Material: metal color:RED Module interface: 1. DC+: positive power supply (VCC) 2. DC-: negative power supply (GND) 3. IN: can be high or low level control relay Relay outputs: 1. NO: normally open relay interface 2. COM: Common Interface Relays 3. NC: 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 Package: 1*1CH relay module Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
