Web Based Modbus TCP/Modbus RTU I/O Module with 8 Digital Output and 14 Digital Input Channels


Web Based Modbus TCP/Modbus RTU I/O Module with 8 Digital Output and 14 Digital Input Channels


*** This product has been phased out and replaced with ET-7052 ***

ET-6052D ApplicationThe ET-6000 series also supports various Modbus functions. For example, Modbus/TCP slave, Modbus/TCP to Modbus/RTU gateway, Modbus/RTU master, Modbus/RTU slave; meaning the ET-6000 series can easily be integrated into any SCADA software environment using the Modbus protocol.

The ET-6000 series modules are designed to be used in Industrial monitoring and measurement applications. The hardware has been manufactured to survive in harsh and noisy environments. The module contains 3-way isolation against noise and surge signals, has a wide range of power input (+10 ~ +30VDC) and can operating at temperature ranging from -25°C ~ +75°C.


  • Built in Web Server
    • Each ET-6000 module has a built - in web server that allows the users to easily configure, monitor and control the module from a remote location using a regular web browser.

  • Web HMI
    • The Web HMI function allows users to create attractive, dynamic web pages to monitor and control the I/O points. Users can upload specific I/O layout pictures (bmp, jpg, gif formats) and define a description for each I/O point. No HTML or Java skills are needed to create the web pages.
  • Communication Security
    • An Account and password is needed when logging into the ET-6000 web server.
    • An IP address filter is included; which can be used to allow or deny connections from specific IP addresses.
  • Modbus protocol
    • The Modbus/TCP slave function on the Ethernet port can be used to provide data to remote SCADA software. 
    • The Modbus/RTU slave function on the RS-232 port can be used to connect to a local HMI.  
    • The Modbus /TCP to Modbus/RTU gateway function through the Ethernet port to the RS-232 port can be used to upgrade a serial device with Ethernet communication ability
  • Built-in Multi-function I/O
    • An LED indicator is used for each DI or DO channel
    • All Digital Output modules provide :
  • Power on value (On boot up, the DO status is set to the Power-on value)
  • Safe value (If Modbus/TCP communication is lost for a specified period,the DO status is set to the safe value)
  • All Digital Input modules provide :
    • High/Low latched status
    • DI channels can also be used as DI status and 16-bit low speed (100Hz) counters
  • All-in-one module
    • The various I/O components are mixed with multiple channels in a single module
    • Provides the most cost effective I/O usage and enhances performance of the I/O operations
  • 3-way isolated noise/surge protection
    • Potect the hardware from damage caused by noise and surges
    • Designed with isolation circuits for Ethernet, I/O and Power.
  • Portable Configuration
    • All configuration settings can be saved to the EEPROM on the ET6000
    • EEPROM is mounted on a daughter board (called the “portable” board)
    • The settings can stored and easily backed up and moved.
  • Built-in Dual Watchdog
    • Dual Watchdog consists of a Module Watchdog and a Host Watchdog.
    • Module Watchdog is a built-in hardware circuit
      • Can be used to monitor the operation of the module
      • Will reset the CPU module if a failure occurs in either the hardware or the software.
    • Host Watchdog is a software function
      • Can be used to monitor the operating status of the host
      • Is used to prevent network communication problems or host failures
  • Automatic MDI / MDI-X crossover for plug-and-play
    • RJ-45 port supports automatic MDI/MDI-x that can automatically detect the type of connection to the Ethernet device without requiring special straight or crossover cables.
  • Ventilated housing designed to operate between -25°C and +75°C
    • The ET-6000 is housed in a plastic-based shell/case with a column-like ventilator that helps to cool the working environment inside the shell/case
    • Allows the ET-6000 to operate at temperatures ranging from -25°C and +75°C.
  • I/O pair connection
    • This function is used to create a DI to DO pair through the Ethernet.
    • Once the configuration is complete, the ET-6000 module can poll the status of local DI channels and then use the Modbus/TCP protocol to continuously write to a remote DO device in the background.
