Description

The Bachmann ME203/CN Processor Module is a compact CPU module for the Bachmann M1 automation controller platform. The ME203/CN combines processor capability, memory resources, communication interfaces, and integrated power supply functions in a single controller module for space-efficient automation installations.

The processor modules of the ME203 seriesextend the range of the M1 controller familyin terms of reduced power consumption andmoderate cycle times. With an extremely slimdesign of only one module width, ME203 CPUsoffer all the essential features of larger typeseries but with a lower power consumption.

Several networking and power supply options scalethe module ideally for smaller applications. Asfully-fledged M1 CPUs, ME203 processor modulesare not only configured with the same tools asthe high-end families MX and MPC, but are alsofully code and application compatible, althoughthey have less memory and fewer interfaces. 

Information

Overview Manuals Application Notes Product Applications Connections and Wiring

Features:

  • 80386 EX processor
  • Optional integrated power supply, 17 W / 24 V DC
  • 2 serial interfaces
  • Battery backed real-time clock (RTC)
  • Status displays for RUN, INIT and ERROR
The ME203/CN utilizes an Intel 80386EX processor operating at 33 MHz and includes 8 MB DRAM, 512 kB battery-backed SRAM, and 8 MB file flash memory for application programs and system data storage. The integrated memory structure allows the ME203/CN to execute automation applications while retaining important operating data during power interruptions through battery-backed SRAM storage.

The ME203/CN provides integrated communication interfaces including one CAN/CANopen interface, one RS232 interface, and one configurable RS232/RS422/RS485 interface. These communication ports allow the ME203/CN to connect with distributed devices, operator interfaces, sensors, drives, and other automation components. The CAN/CANopen interface provides a standardized communication method for integrating field devices within industrial control networks.

The ME203/CN Bachmann Processor module may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

The ME203/CN includes an integrated 17 W power supply and is for installation within the Bachmann M1 controller system. The compact processor design reduces the requirement for additional controller hardware while maintaining compatibility with Bachmann programming and configuration tools. The module also provides a PCC slot for additional memory or expansion functions according to the system configuration.
 
The ME203/CN is suitable for industrial automation applications including machine control, production equipment, energy systems, and process automation. As part of the Bachmann M1 controller family, the ME203/CN provides a reliable processing platform for existing automation installations requiring replacement CPU modules or maintenance support for legacy Bachmann control systems

Technical notes

All modules have two serial interfaces and afront slot for one PC card. The optional Ethernetinterface allows integration in 10 / 100 Mbit /s networks at full data rate. With the retentiveprogram and data storage devices, also largerprojects can be handled without the need forexternal media. In addition to the supply of theprocessor module, an integrated optional powersupply provides 17 W for extra I/O modules.

FAQs

  • What does the -CN suffix mean?

    +
    It indicates a cold climate-compliant hardware variant built to operate in harsh, low-temperature environments.
  • What are the technical hardware specifications of the ME203/CN?

    +
    The ME203 series features a 33MHz CPU, 8MB DRAM, 512kB SRAM, and 8MB of file-flash memory. It features an integrated 17W power supply to support extra local I/O modules, an integrated PC Card slot (PCC), and two onboard serial interfaces
  • Is it cross-compatible with higher-end Bachmann families?

    +
    Yes. The ME203/CN is fully application and code-compatible with the high-performance MX and MPC controller families. This allows developers to port over software configurations smoothly despite the ME203 having a smaller physical profile, fewer hardware interfaces, and reduced memory.
  • What onboard interfaces are available?

    +
    The module provides 1x CAN/CANopen port, 1x RS232 serial port, 1x RS232/422/485 serial port, and a front-facing PC Card (PCC) slot.
