LORDWORLD 8-channel relay module in ABS rail-mount enclosure with USB and BOOT pin breakout

LORDWORLD

LORDWORLD Industrial 8-Channel Relay Module for Raspberry Pi Pico

SKU CH-3SR5-E7CT4

Industrial 8-channel relay board for Raspberry Pi Pico with isolated power supply, photocoupler isolation, 10A 250V AC or 30V DC contacts, ABS rail-mount enclosure.

  • Stable isolated power without an extra supply thanks to onboard unibody isolation
  • External high-voltage noise blocked by onboard photocoupler isolation
  • Switch heavy loads up to 10 A at 250 V AC or 10 A at 30 V DC
  • Secure DIN-rail mounting in a protective ABS enclosure for safe installation
  • Debug code through breakout USB and BOOT pins without opening the case

Industrial Relay Board for Pico

The LORDWORLD module adds eight independently switched channels to a Raspberry Pi Pico, letting makers and engineers control mains or low-voltage loads from a single microcontroller. It targets anyone building automation, test rigs or home-control projects that need reliable galvanic separation between logic and power circuits.

Contact rating 10A at 250V AC or 30V DC

Each relay is rated for 10 amperes at 250 volts AC or 10 amperes at 30 volts DC, so the board can switch heaters, pumps, lighting or similar loads directly. Onboard photocoupler isolation and a unibody isolated power supply keep high-voltage transients away from the Pico, removing the need for an extra isolated supply on the relay side.

Rail-mount ABS enclosure with debug access

The ABS housing clips onto a DIN rail and exposes a USB port plus the BOOT pin, so firmware can be updated or debugged without opening the case. Installers must still follow safe mains-wiring practice; the enclosure does not replace proper cable glands or circuit protection. Buyers needing more than eight channels or higher current per channel should look elsewhere.

Questions about this item

What can the 10 A contact rating actually switch in a live project?

Each channel handles up to 10 A at 250 V AC or 10 A at 30 V DC, so it can drive mains appliances, heaters, motors or DC loads within those limits.

How does the onboard isolation affect the signals coming from the Pico?

The built-in photocoupler isolation and unibody power supply separate the Pico's logic side from the relay coils, preventing high-voltage transients from reaching the microcontroller.

What mounting options does the ABS enclosure give me?

The enclosure includes integrated rail-mount support for DIN-rail installation and can also be screw-fixed to a panel or chassis.
