I-8811 Embedded Controller - RS485 : Master - 8 slot

The I-8811 is a Serial Embedded Controller with 8 I/O slots. This unit supports both 8k series parallel I/O modules and 87k serial I/O modules, such as analog input/output, digital input/output and counter/frequency modules. It is supplied with MiniOS7 and can be programmed for a wide variety of tasks/applications. The unit is equipped with four serial COM ports (inc. RS485 & RS232) and by using the optional S-256 (256kbytes) or S-512 (512 kbytes) battery backup SRAM, they can also be configured as data loggers.

• Provide multi Serial Port interface on back plane.
  COM1: RS-232
  COM2: RS-485
  COM3: RS-232/RS-485
  COM4: RS-232

• Provides a hardware serial number or an ASICKey to protect designated systems

• The built-in watchdog circuit will reset the CPU module if a failure occurs in either the hardware or software, making the controller 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 modules

• Firmware updated via the RS-232 port

• Ventilated housing designed to operate between -25°C to +75°C
• DIN rail clips or Screw holes on each corner allow the control unit to be easily mounted
• Frame Ground provides enhanced static protection (ESD) capability and ensures that the module is more reliable

• Equipped with MiniOS7, an embedded OS similar to DOS that is developed by ICP. It provides full C library functions such as 8K, 87K I/O, 7-segment LED, RTC (real time clock), EEPROM etc.
