2 Channel 5V Relay Module Board Shield with Optocoupler Support High and Low Level Trigger for Arduino

คุณสมบัติ 2 Channel 5V Relay Module Board Shield with Optocoupler Support High and Low Level Trigger for Arduino

• one, 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 voltage 5V, 9,12V, 24V to choose from;
  4, the module can be set to trigger high or low with jumpers;
  5, fault-tolerant design, even if the control line is broken, the relay will not operate;
  6, the power indicator (green), relay state indicator (red)
  7, user-friendly interface design, all interfaces are available through the wiring terminal direct connection leads, very convenient
  8, module size: 50mm * 41mm * 18.5mm (L * W * H)
  9 with four mounting bolts holes, hole 3.1mm, 44.5mm * 35.5mm pitch
  Two, module interface:
  1, DC +: positive power supply (voltage relay according to requirements, 5V.9V.12V and 24V selection)
  2, DC-: negative one
  3, IN1: 1 signal triggers the end of the road, you can set a high or low level control relay
  3, IN2: 2 signals trigger terminal can be set high or low level control relay
  Relay outputs:
  1, NO1: after 1 relay normally open interfaces, relay before hanging, pull and COM1 short
  2, COM1: 1 relay common interface
  3, NC1: 1 NC relay interfaces, relay before the COM1 short, after the pull-vacant
  4, NO2: 2-way normally open relay interfaces, relay before hanging, pull back and COM2 shorted
  5, COM2: 2 relay Common Interface
  6, NC2: 2-way normally closed relay interfaces, relay before and COM2 short, after the pull-vacant
   
  High and low end of the trigger selection:
   
  1.S1 1 relay high and low trigger selection;
   
  2.S2 2 relay high and low trigger selection;
   
  When 3.com with low short circuit, triggering the corresponding relay is low, and high when com shorted high level trigger
