The I-8431-80/ I-8831-80 are ethernet embedded controller with 4/8 I/O slots. Both are equipped with MiniOS7,an embedded OS similar to DOS that is developed by ICPDAS Co., LTD. 

The MiniOS7 can boot up in a very short time (0.4~0.8 second).It has built-in hardware diagnostic function, and supports the full functions to access all 8K and 87K series I/O modules, such as DI, DO, DIO, AI, AO, Counter/Frequency, motion modules etc.

To simplify the TCP/IP program developing process, we designed a XServer architecture. It is a reliable, opened, expandable, all purposed,and easily to be used library. The Xserver implements 90% functionalities of Ethernet communication. Refer the rich demo programs we provided, software engineer can easily finish the 10% remaining funtionalities and greatly shorten the developing time. 

The I-8431-80/I-8831-80 are equipped an ethernet port and their back planes are equipped three serial COM Port, they include RS-232 and RS-485 ports and can be used in remote data acquisition and control applications, including environment monitoring, power management and factory automation. By using S-256 (256 KBytes) or S-512 (512 KBytes)battery backup SRAM, they provide data logger storage function.

Note: S256 and S512 are optional accessories.


Provide multi Serial Port interface on back plane. 
  COM1: RS-232 
  COM3: RS-232/RS-485 
  COM4: RS-232

  The built-in watchdog circuit will reset the CPU module if a failure occurs in either the hardware or software, allowing thecontroller system more reliable and stable in harsh and noisy environments.

  Dual Bus designed to supports I-8K and I-87K series I/O modules, such as DI/DO, AI/AO, Counter/Frequency modules
  Compact I/O Expansion slot allows the quick installation of various 8K and 87K I/O module
Serial Port
  The XServer architecture greatly simplify the programming of TCP/IP protocol.
  Supports the VxComm technique for all ports (Serial Port and Ethernet Port).
  Firmware updated via the RS-232 port

  Ventilated housing designed to operate between –25°C to 

Ventilated Housing
  Using DIN rail clips or Screw poles around the corners 
  allows the control unit to be easily mounted on the control
Frame Ground provides a path for bypassing ESD, allowing enhanced static protection (ESD) capability and ensures that the module is more reliable.
