- vVersatile box-style I/O carrier from the Versamax series
- This unit facilitates efficient connections and wiring with 36 IEC box-style terminals
- Allowing for the integration of one I/O module to achieve effective system communication and control
The IC200CHS022L is a compact, box-type I/O carrier board designed and manufactured by GE Fanuc (now Emerson) specifically for VersaMax modular PLC systems. As the physical and electrical backbone of the entire automation control system, its core function is to provide robust mechanical mounting brackets, backplane communication connections, and field device terminals for any VersaMax I/O module (such as digital, analog, or special function modules).
In terms of interface configuration and physical safety features, the IC200CHS022L offers superior field cabling management and tool-free maintenance. The base integrates 36 IEC-compliant box-type terminals, safely supporting up to 32 independent I/O channels and 4 power and common ground terminals (the common power terminal supports a maximum current of 8 A, and individual terminals support a maximum current of 2 A). To prevent incorrect hardware insertion due to human error during subsequent maintenance or module replacement, the base surface is equipped with an easily adjustable mechanical locking knob. Users can ensure complete locking and engagement with the slots on the bottom of the I/O modules by setting the mechanical locking knob.
The IC200CHS022L General Electric Compact Box-Style I/O Carrier may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
1.Space-Constrained Control Cabinets: Suitable for compact electrical cabinets with limited DIN rail space. Box-type screw terminals provide 36 heavy-duty connection points directly below the functional modules, eliminating the need for separate external terminal blocks and reducing cabinet footprint.
2.Remote Distributed I/O Stations: Deployed in remote control junction boxes in large manufacturing plants (e.g., connected via Profibus, DeviceNet, or Ethernet/IP network interface modules). It serves as a local physical terminal interface for local sensors and actuators.
3.Multi-Channel Digital I/O Interfaces: Perfect for standard 32-channel digital input (IC200MDL650) or output modules. It directly assigns 32 independent junction box terminals to discrete field hardware such as proximity sensors, limit switches, solenoid valves, push-button stations, and indicator lights, with the remaining 4 terminals handling common power and ground loops.
4.Analog and Temperature Sensor Assemblies: For mounting 4-channel, 8-channel, or 12-channel analog inputs (voltage/current) and RTD/thermocouple modules. Integrated plastic cable trays and hinged covers protect sensitive low-voltage analog circuitry from physical interference and industrial debris.
5.Quick-disconnect maintenance wiring: Ideal for automated assembly lines requiring rapid module replacement during downtime. Since field wiring is permanently attached to the IC200CHS022L carrier board, technicians can hot-swap or replace top-mounted active electronics modules without disconnecting any field wiring.
6.Error-proof hardware keying: Deployed on multi-slot machine control racks to prevent damage from mixed analog and digital voltages. Maintenance teams use built-in mechanical keying knobs to lock the slots to specific module profiles, ensuring only the correct replacement module clicks into the appropriate socket.
In terms of operating principle, the IC200CHS022L base is primarily based on electrical expansion and passive bridging interconnection mechanisms using a parallel backplane bus. As a passive connection motherboard, it does not contain complex microprocessors or communication protocol chips. Instead, it utilizes male and female connectors on the left and right sides to horizontally connect adjacent bases to the rails and directly connects to the internal VersaMax parallel backplane bus.
When an upper-level I/O module is inserted into the base, the module's internal circuitry connects to the bus through the center socket of the base, establishing data communication and power sharing with the main control network or power module. Simultaneously, 36 metal box-type terminals on the bottom of the base transmit electrical signals from external sensors or actuators directly to the acquisition pins of the upper-level module via point-to-point physical conduction through the internal precision printed circuit board (PCB).
A metal spring on the bottom of the base maintains tight contact with the rails, safely releasing high-frequency electromagnetic interference and surge transient voltages to ground, thus achieving efficient and reliable closed-loop electrical signal transmission throughout the entire path.
