Industrial 8-Channel Relay Module For Pico: Embedded Protections: Power Supply Isolation & Photocoupler Isolation
Features At A Glance:
- Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal
- Onboard photocoupler isolation, prevent interference from external high-voltage circuit connected to the relay
- High quality relay, contact rating: 10A 250V AC or ≤10A 30V DC
- ABS protection enclosure with rail-mount support, easy to install, safe to use
- Breakout USB port and BOOT pin, make it easy to debug without disassembling the enclosure
- PWR indicator, RGB LED, and passive buzzer outside the enclosure
- Comes with development resources and manual (Raspberry Pi Pico C/C++ and MicroPython examples)
