GE IC200CHS022E

Description

Product Overview

The GE IC200CHS022E is a compact, high-performance CPU (Central Processing Unit) module for the VersaMax Micro family of programmable logic controllers (PLCs). This module is the central brain of the control system, executing user-written logic, managing I/O, and handling communication tasks. Designed for small to medium-sized automation applications, the GE IC200CHS022E offers a balanced mix of processing power, memory capacity, and integrated features in a space-saving package. It is engineered to deliver reliable control for machine automation, process skids, and standalone systems where cost-effectiveness and simplicity are key. The E suffix in the model indicates an enhanced feature set, which often includes more user memory, faster execution, or additional communication capabilities compared to base models. As the core of a VersaMax Micro system, the GE IC200CHS022E provides a solid foundation for building robust and efficient control solutions.

Product Parameters and Specifications

• Manufacturer: GE (General Electric), now part of Emerson’s Machine Automation Solutions.

• Product Line: VersaMax Micro PLC.

• Module Type: CPU / Processor Unit.

• Processor: 32-bit microprocessor optimized for deterministic logic execution.

• User Memory: Substantial non-volatile memory for storing the control program, configurations, and data registers. The “022” and “E” denote a specific memory size and performance tier.

• Integrated I/O: This CPU typically includes a base number of onboard I/O points:

  • Digital Inputs (DI): e.g., 12 or 14 points, 24V DC sinking/sourcing.

  • Digital Outputs (DO): e.g., 10 points, relay or transistor outputs.

• Communication Ports: Features built-in serial ports for programming and networking:

  • RS-232 Port: Primarily for connecting a programming device (PC) or an operator interface (HMI).

  • RS-485 Port: Supports multi-drop networks for communication with other devices (e.g., drives, other PLCs) using protocols like SNP, Modbus RTU (Master/Slave), or Genius bus.

• Expansion Capability: Supports the addition of VersaMax Micro expansion I/O modules via a local bus connector to increase the number of digital and analog I/O points.

• Real-Time Clock: Often includes a built-in battery-backed real-time clock for time-stamping events and scheduling.

• Programming Software: Programmed using Emerson’s (formerly GE) Proficy Machine Edition (PME) Logic Developer PLC software.

Advantages and Key Features

1. All-in-One Compact Design: The GE IC200CHS022E integrates the processor, power supply, communication ports, and a useful set of onboard I/O into a single, compact unit. This drastically simplifies system design, reduces component count, and minimizes panel space for many small applications.

2. Cost-Effective for Standalone Machines: By providing a ready-to-use controller with built-in I/O, it eliminates the need for a separate CPU rack, power supply, and initial I/O modules, offering a very attractive total cost of ownership for OEMs and end-users.

3. Robust Communication Options: The dual serial ports with support for industry-standard Modbus RTU make the GE IC200CHS022E highly versatile for integrating with a wide range of third-party devices, from HMIs and drives to sensors and bar code readers.

4. Easy to Install and Wire: With its integrated I/O and clear terminal block labeling, installation and wiring are straightforward, reducing engineering and commissioning time.

5. Scalable via Expansion I/O: When the onboard I/O is insufficient, the system can be easily and cost-effectively scaled by adding discrete, analog, or special function expansion modules directly to the CPU, protecting the initial investment.

Application Case Studies

• Small Packaging Machine: The GE IC200CHS022E is ideal for controlling a standalone carton erector and sealer. Its onboard digital inputs read sensor statuses (photoeyes, limit switches), and its relay outputs directly control solenoids, motors, and indicators. The RS-485 port connects to a simple text display HMI for operator interaction.

• Industrial Oven or Furnace Control: For a batch oven, the CPU runs the temperature profile logic. An attached thermocouple input module reads temperature, and an analog output module controls a proportional gas valve. The built-in real-time clock manages timed soak periods.

• Irrigation Pump Control Panel: In an agricultural setting, the controller manages pump start/stop sequences based on pressure switch inputs (onboard DI) and timer schedules. Its Modbus RTU capability allows it to communicate flow data to a central SCADA system monitoring the entire irrigation network.

Selection Suggestions and Important Notes

• Selection Suggestion:

  • Choose the GE IC200CHS022E when you need a compact, self-contained PLC for a small machine or process skid that can largely be handled by its onboard I/O count and types.

  • It is an excellent choice for applications requiring reliable serial communication (Modbus RTU) to peripherals, or for modernizing older panels that use serial HMIs.

  • Select this CPU when working within an existing facility that standardizes on GE/Emerson platforms or when the Proficy Machine Edition programming environment is available.

• Important Notes:

  • Onboard I/O Type Verification: Carefully check whether the onboard outputs of the IC200CHS022E are relay or transistor type. Relays can switch AC/DC loads but have limited life; transistors are for DC only but are long-lasting. Choose based on your load requirements.

  • Expansion Limits: Be aware of the maximum number of expansion modules the CPU can support (both physically and in terms of I/O address space). Do not exceed these limits in your design.

  • Power Budget Calculation: When adding expansion modules, you must calculate the total 5V DC and 24V DC current draw from the CPU’s internal power supply. Each expansion module has specific requirements; exceeding the budget will cause unstable operation.

  • Battery for Real-Time Clock and Memory: If the application requires retention of the real-time clock or retentive memory through a power outage, ensure the optional battery (e.g., IC200BAT001) is installed.

  • Software Version Compatibility: Ensure the version of Proficy Machine Edition you are using supports the IC200CHS022E CPU and can communicate with its firmware. A firmware update of the CPU may be necessary.
