2-Channel Relay Module 5V H/L High and Low Level Trigger with Optocoupler for Arduino AVR PIC

Description:

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: 50x41x 18.5 mm (LxWxH)

Module interface:

• DC+: positive power supply (VCC)
• DC-: negative power supply (GND)
• IN1: can be high or low level control relay
• IN2: can be high or low level control relay

Relay outputs:

• NO1/2: normally open relay interface
• COM1/2: Common Interface Relays
• NC1/2: normally closed relay interface

High and low level trigger options:

• S1/2: Switch option for channel 1 or 2 relay
• It is low level trigger when jumper connect to LOW pin
• It is high level trigger when jumper connect to HIGH pin

What's in the Package:

• 1pcs 2-Channel 5V Relay Module H/L Trigger with with Optocoupler
