What Is the IC200ETM001 Expansion Connector?
The GE Fanuc IC200ETM001 is an expansion connector module from the VersaMax product family. It enables your VersaMax PLC system to support up to 7 additional racks, each accommodating up to 8 I/O modules. This module acts as the critical bridge between your CPU or Network Interface Unit and the expansion receiver modules.
If your application has outgrown its current I/O capacity, the IC200ETM001 offers a practical path to scale without replacing your entire control platform. It installs on a DIN rail and attaches to the VersaMax CPU on the left side, making integration straightforward for technicians familiar with the VersaMax architecture.
Key Technical Specifications
Connector and Interface Design
The IC200ETM001 features a 26-pin female connector on the front of the module. This connector links directly to the expansion receiver module. A 16-pin serial port connector (male) sits at the upper left corner. Technicians use this port to upload firmware updates to the nearby Network Interface Unit (NIU) in the VersaMax PLC.
LED Status Indicators
Two LEDs provide at-a-glance diagnostics. One LED confirms that the module receives power from the NIU or CPU. When this LED turns off, it signals that the module is disconnected from the NIU or CPU, or that power has not been delivered. The EXP TX LED blinks to show active communication between the bus receiver module and the expansion transmitter. When communication stops, the EXP TX LED remains off.
Expansion Capacity and Cable Lengths
The module supports up to 7 receiver modules. Cable length depends on the module type you choose. Isolated module expansion cables can run up to 15 m, while non-isolated module expansion cables extend up to 750 m. This flexibility lets you place expansion racks at significant distances from the main CPU when using non-isolated configurations.
Data Rate
The IC200ETM001 operates at a data rate of 250 bits/sec. This rate suits the deterministic communication needs of VersaMax expansion I/O without introducing unnecessary overhead.
Where the IC200ETM001 Fits in Your System
Manufacturing Floor Expansion
A production line adds new sensors and actuators but the existing VersaMax PLC rack is full. The IC200ETM001 lets you add up to 7 racks without replacing the CPU. Each rack holds up to 8 I/O modules, giving you room for dozens of additional points.
Long-Distance Remote Racks
When equipment sits far from the main control cabinet, the 750 m non-isolated cable length becomes valuable. You can place I/O racks closer to field devices, reducing wiring runs and improving signal integrity.
Firmware Maintenance Access
The 16-pin serial port simplifies firmware updates to the NIU. Maintenance teams can perform updates without removing the module from the DIN rail.
Installation and Setup Guidance
Mount the IC200ETM001 on a DIN rail and attach it to the left side of the VersaMax CPU. Connect the 26-pin female connector to the expansion receiver module. Verify that the power LED illuminates after applying power from the NIU or CPU. If the EXP TX LED does not blink, check the cable connection between the bus receiver and expansion transmitter. Use the 16-pin serial port only for firmware uploads to the NIU.
Maintenance and Reliability
Inspect the module periodically for loose connections and LED status. The two LEDs serve as your primary diagnostic tool. A dark power LED points to a power supply or connection issue. A dark EXP TX LED indicates a communication problem. Keep the DIN rail and connectors free of dust and debris. Follow the manufacturer’s safety manual for all maintenance activities. Please verify current lifecycle status and availability with SpareTechPLC before ordering.
Compatibility and Integration
The IC200ETM001 works with both isolated (ERM001) and non-isolated (ERM002) expansion receiver modules. It integrates with the VersaMax CPU and Network Interface Unit. The module supports isolated and non-isolated module configurations, giving you flexibility in system design. Always confirm that your receiver module type matches your cable length requirements.
Buyer’s Checklist Before You Order
- Confirm you need up to 7 additional racks.
- Choose isolated (15 m) or non-isolated (750 m) cable based on distance.
- Verify your CPU or NIU supports expansion via the IC200ETM001.
- Check that you have the correct receiver module (ERM001 or ERM002).
- Contact SpareTechPLC to confirm availability and compatibility with your existing VersaMax setup.
Frequently Asked Questions
