Hetai Tech 8-way Network Relay Module 10A 32-bit

SKU CH-CY26-4JGX2

An 8-channel 10 A relay module with 32-bit MCU for LAN-based switching and MODBUS TCP integration

  • 8-way relay module controls lights and motors from phone or computer
  • 10 A switching capacity handles mains-powered loads safely
  • 32-bit MCU provides reliable network link with auto-reconnect
  • Four simultaneous TCP client connections exceed typical single-link designs
  • MODBUS TCP support integrates directly with Kingview SCADA software

8-Way Relay Controller for LAN Automation

This 8-way network relay module switches up to 10 A per channel and provides eight switch inputs for sensors or buttons. It operates as a TCP server, TCP client or UDP device and supports four simultaneous client connections. A 32-bit microcontroller handles MODBUS TCP communication for integration with SCADA software such as Kingview. C++ source code is supplied for custom development.

Suits installers building local smart-home

The hardware is designed for wired LAN control; external internet access requires a separate dynamic-DNS or tunneling service that the buyer must arrange. No mobile application is included, so teams needing a ready-made phone app should look elsewhere. Buyers who require more than eight switched circuits or higher current per channel will need additional modules.

10 A per channel switching capacity

Each of the eight relays is rated for 10 A at the stated voltage, which determines the maximum load the module can handle directly. The 32-bit processor ensures reliable protocol handling and automatic reconnection after network drops. Verify that the connected devices do not exceed this per-channel rating before installation.

Questions about this item

How can I verify the module is operating correctly after wiring it to the network and connecting loads?

Confirm the Ethernet link LED is active, use the supplied network parameter software to read back the IP settings, send a MODBUS TCP command to toggle each of the 8 relay channels, and observe the corresponding normally open or normally closed contacts change state.

What items are included with the 8-way relay module and what must I obtain separately?

The module itself is supplied; you must provide a 10 A rated power source for the relay contacts, Ethernet cabling for LAN access, any sensors or switches for the 8 switch inputs, and a peanut-shell service or domain-name binding if remote internet control is required.

Which version should I choose if I need up to four simultaneous TCP client connections and a 32-bit MCU?

The described unit already supports four concurrent TCP client connections in server mode and uses a 32-bit single-chip microcomputer, so the standard model meets both requirements.
