Description
A versatile relay board with opto-isolated inputs. Each channel can drive up to 10A@28VDC
Features
- While marked as requiring 5V supply and logic, we've found this board to work fine at 3.3V
- Features a jumper to disconnect the VCC line from the transistors driving the relays, effectively giving you a way to "dry-run" this module
- Features opto-isolators and transistors to drive the relay coils, meaning that you only need 2mA per pin on your microcontroller to drive it
Specifications
- Dimensions: 76mm x 55mm x 19mm
- Optoisolator/LED Current Draw: 2mA per relay
- Relay Coil Current Draw: 60mA per relay
