8-Channel Relay Module 12V H/L High and Low Level Trigger with Optocoupler for Arduino AVR PIC

Description:

Module description:

• Normally Open Pin Maximum load: AC 250V/10A, DC 30V/10A
• Using SMD optocoupler isolation, driving ability, stable performance; Trigger current 5mA
• 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 size: 141.5 x50x 18.5 mm (LxWxH)

Module interface:

• DC+: positive power supply (VCC)
• DC-: negative power supply (GND)
• IN(1~8): can be high or low level control relay

Relay outputs:

• NO(1~8): normally open relay interface
• COM(1~8): Common Interface Relays
• NC(1~8) normally closed relay interface

High and low level trigger options:

• S(1~8): Switch option for channel 1st to 8th 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 8-Channel 12V Relay Module H/L Trigger with Optocoupler
