8 relays, optically isolated, perfect for Arduino projects!


Description [Hide]

Ever need a stack of relays for a project? Here's 8 of them!

These are perfect relays for any 5V logic. Input lines are optically isolated and can be driven with 5mA of current. These are designed to be fault-tolerant: even if the control line is broken, the relay will not engage. Indicator lights allow you to know the status of each relay at a glance. Each relay can be jumper selected for either high or low-level input, making them completely configurable!

 

Specifications:

  • Relay Maximum Load: AC 250V/10A, DC 30V/10A
  • Isolation: Opto-coupled
  • Triggering Current: 5mA
  • Operating Voltage: 5V
  • Triggers: High/Low individually jumper selectable
  • Indicators: Relay Status: Red, Power: (Green)
  • All Connections: Screw Terminal
  • Dimensions: 142mm x 50mm x 20mm

Connection Map:

  • DC+: positive power supply (VCC)
  • DC-: negative power supply (GND)
  • IN1,2,3,4,5,6,7,8: Input signal per channel
  • S1,S2,S3,S4, S5,S6,S7,S8 Jumper setting for High/Low Level
  • NO1,2,3,4,5,6,7,8: normally open relay terminals
  • COM1,2,3,4,5,6,7,8: Common relay terminals
  • NC1,2,3,4,5,6,7,8: normally closed relay terminals
