Here’s a clearer and more polished rewrite of your description:
A versatile relay board with opto-isolated inputs
This relay board offers reliable switching capabilities, with each channel rated for up to 10A at 28VDC.
This relay board offers reliable switching capabilities, with each channel rated for up to 10A at 28VDC.
Features
- Although labeled for a 5V supply and logic, the board also operates reliably at 3.3V.
- Includes a jumper to disconnect the VCC line from the transistor drivers, allowing you to test (“dry-run”) the module without energizing the relays.
- Built with opto-isolators and transistor drivers for each relay coil, enabling control with only 2mA per microcontroller pin.
Specifications
- Dimensions: 73 × 54 × 19 mm
- Opto-isolator/LED Current Draw: 2mA per relay
- Relay Coil Current Draw: 60mA per relay
