LORDWORLD 8DI 8DO PoE Modbus IO Module development board

SKU CH-MNMT-017FR

Provides eight digital inputs and eight digital outputs with Modbus TCP/RTU over dual Ethernet ports, powered by IEEE 802.3af PoE or DC 7-36V, featuring optocoupler isolation, TVS surge suppression.

  • 8 digital inputs and 8 digital outputs for industrial control via Modbus TCP/RTU
  • PoE power to IEEE 802.3af plus DC 7-36 V supply for flexible cabinet wiring
  • NPN/PNP inputs with optocoupler isolation, debounce and DI/DO linkage logic
  • 500 mA sink open-drain outputs with flyback diodes for relays and solenoids
  • Dual Ethernet ports with cascade, TVS surge suppression, resettable fuse and DIN rail mount

Industrial 8-channel I/O module

The LORDWORLD 8DI 8DO PoE Modbus IO Module is a new DIN-rail development board for industrial automation. It provides eight digital inputs and eight digital outputs controlled over wired Ethernet using Modbus TCP or Modbus RTU. The unit targets engineers building remote I/O systems for cabinet-level monitoring and control.

Dual power with PoE and 7-36 V DC

The board accepts IEEE 802.3af PoE and a 7-36 V DC supply, so it can be powered from the network cable or a local source. Both inputs include isolation, TVS surge suppression and a resettable fuse to protect the controller in harsh electrical environments.

DIN-rail mounting with cascade ports

Two Ethernet ports allow daisy-chain topology, reducing cabling in multi-node cabinets. Status LEDs show I/O, MCU and link state for quick diagnostics. Installers must ensure the 500 mA per-channel sink rating suits their relays or solenoids, and that open-drain wiring matches the load requirements.

Questions about this item

How many sensors or actuators can I connect to the 8 digital inputs and 8 digital outputs on this module?

You can wire up to eight sensors to the digital inputs and drive up to eight loads from the digital outputs. Each output sinks up to 500 mA, suitable for relays or solenoids.

What does IEEE 802.3af PoE actually power on this board, and what voltage range does the DC jack accept?

The IEEE 802.3af PoE port supplies the whole module over the Ethernet cable, while the DC input accepts 7 to 36 V for installations without PoE.

What mounting hardware is required to install this unit in a control cabinet?

The enclosure clips onto a standard DIN rail; no extra brackets or screws are needed.
