Green circuit board with 32 relay modules inside a black ABS enclosure

LORDWORLD

LORDWORLD Modbus RTU 32-Ch Relay Module RS485 development board

SKU CH-TT8F-ADVKD

32-channel relay module with RS485 Modbus RTU interface, cascadable up to 255 addresses and built-in isolation for industrial use

  • Control up to 32 independent relay channels from one board
  • Daisy-chain up to 255 modules on a single RS485 bus
  • Flash-on/flash-off timing automates relay pulses without host code
  • Onboard power-supply isolation removes the need for an extra isolated source
  • ADI magnetic plus optocoupler isolation protects signals from high-voltage interference

Industrial relay board for Modbus networks

The LORDWORLD board provides 32 relay channels controlled over an RS485 link using the Modbus RTU protocol. It targets engineers and integrators building automation cabinets that need many switched outputs on a single bus.

Cascadable address range up to 255 nodes

Each unit can be assigned a unique address from 1 to 255, allowing many boards to share the same RS485 line without conflicts. This addressing scheme is the key specification for planning a multi-node installation.

Isolated power and signal paths for continuous

Onboard unibody power isolation supplies a stable isolated voltage without an external source, while ADI magnetic isolation and optocouplers protect the logic side from high-voltage transients. The design supports sustained switching with strong anti-interference and low power draw.

Questions about this item

How many relays can I control simultaneously on this 32-channel board?

All 32 relays can be operated at once because each channel has its own optocoupler and the isolated power supply feeds the whole module without an extra source.

What does the RS485 interface limit in a multi-device setup?

The bus supports addresses 1 to 255, so up to 255 modules can be cascaded on the same RS485 line.

What mounting provision does the ABS case include?

The enclosure has integrated mounting tabs for direct DIN-rail or panel installation without additional brackets.
