2-Channels For Arduino Relay Module Dc 12V H/L Level Triger With Optocoupler Ic

Module description.    1. the module uses genuine quality relay, normally open interfaces Maximum load: AC 250V/10A, DC 30V/10A.    2. using SMD optocoupler isolation, driving ability, stable performance; trigger current 5mA.    3. the module Operating voltage 12V.    4. the module can be high or low by a jumper setting trigger.    5. fault-tolerant design, even if the control line is broken, the relay will not operate.    6. the power indicator (green), the relay status indicator (red).    7. the interface design of human nature, all interfaces are available through a direct connection terminal leads, very convenient.    8. module size: 50mm*40mm*17mm (L*W*H).    Module interface.    1. DC+: positive power supply (VCC).    2. DC-: negative power supply (GND).    3. IN: can be high or low level control relay.    S1.S2. HIGHT OR LOW LEVER.    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.
