LORDWORLD 8-channel Modbus RTU relay module in ABS enclosure with RS485 terminals

LORDWORLD

LORDWORLD 8-Channel Modbus RTU Relay Module RS485 10A 250VAC/30VDC

SKU CH-PAGQ-PFHVG

Controls eight relays rated at 10 A 250 VAC or 30 VDC via Modbus RTU on an RS485 bus with magnetic, optocoupler and TVS isolation

  • Control up to 255 modules on one RS485 bus with configurable addresses
  • Automate timed switching using flash-on and flash-off command arguments
  • Isolated onboard power supply removes the need for an extra isolated source
  • TVS and optocoupler protection guards relays against surges and high-voltage interference
  • 10 A 250 VAC / 30 VDC contacts in a rail-mounted ABS enclosure for safe installation

8-Channel Modbus RTU Relay Module

The LORDWORLD module provides eight independently switchable relays on a single RS485 bus, each rated for 10A at 250VAC or 30VDC. It is built for engineers and system integrators who need reliable, isolated control of mains-voltage loads from a Modbus master. The board ships new in a rail-mounted ABS enclosure ready for cabinet installation.

Isolation and protection features

Onboard unibody power-supply isolation and ADI magnetic isolation remove the need for an external isolated supply while delivering strong anti-interference performance. Optocoupler isolation shields the control logic from high-voltage switching transients, and a TVS array suppresses surge and electrostatic spikes. A reverse-proof circuit prevents damage from accidental wiring errors.

Cascading and mounting

Up to 255 devices can share the RS485 bus thanks to configurable addresses from 1 to 255, and the flash-on and flash-off command lets a relay pulse for a set interval without host intervention. The ABS enclosure clips onto standard DIN rail for quick, secure mounting in industrial panels. Buyers who need wireless connectivity or higher contact ratings should look elsewhere.

Questions about this item

How often should the 10A 250VAC relays be inspected or replaced under normal load?

The relays are rated for 10A at 250VAC or 30VDC; mechanical life typically exceeds 10 million cycles, so replacement depends on switching frequency and load type rather than a fixed schedule.

What limits continuous operation when all eight channels run at full 10A?

The RS485 bus address range of 1 to 255 allows many modules on one line, but the first practical limit is the combined current through the shared power terminals and the enclosure's heat dissipation.

How much heat or noise does the ABS enclosure produce during all-day operation?

The solid-state isolation and optocouplers generate minimal heat; the only audible sound is the mechanical relay click when contacts change state, with no fan or active cooling.
