5V 8 way Optocoupler Isolated Relay Modules

Specifications:

• Channels: 8 Relays
• Relay Voltage: 5V
• Relay Coil Current: 30mA at 5V per relay
• Relay Output Current: 10A at 250VAC, 10A at 20VDC
• Board Supply: 12V supply voltage
• Input Type: Opto Isolated inputs
• Power LED: 1 LED for power indication
• Channel LEDs: 4 LEDs to indicate the state of each relay
• Module dimension: 143mm x 52mm
• Diameter of mounting holes: 3 mm

Pin Setup:

• INx Controls relays 1 to 4  active Low! The relay will turn on when this input goes below about 2.0V
• GND: Connect 0V to this pin. used to power the board (optocouplers and relays)
• VCC: Connect 5V to this pin.  power the board (optocouplers and relays)
• JD-VCC: 5V is Required for the relays. At delivery, a jumper is present on this and the adjacent (VCC) pin
• VCC: T 5V VCC supplied on the main pin connector
• GND:  Connected to 0V pin of main pin header

Please note:

Note: Maximum contact voltage depends on the type of load

The relays used are usually Songle or Tongling, both of good quality and exact specifications

As shipped, the module has a jumper between header pins JD-VCC and VCC (relay power is jumpered to logic power).

Package Includes:

• 5V Optocoupler Isolated Relay Module
