EtherNet/IP and Micro800 Bus Communication Termination
The 2085-ECR provides physical termination for the Micro800 Expansion I/O serial communication bus. Installed on the final expansion module, the unit closes the bus structure and maintains the defined electrical endpoint of the expansion assembly. The module is rated for a 5 V backplane supply with a 10 mA current requirement and supports Micro800 expansion configurations in both non-hazardous and Class I, Division 2 hazardous locations.
The Micro800 platform uses modular I/O expansion, and the bus terminator prevents an open-ended communication path at the last connected I/O module. Correct installation maintains the intended backplane communication topology and module addressing behavior.
Frequently Asked Questions

Q: What backplane electrical rating applies to the 2085-ECR?
A: The module operates with a 5 V backplane rating and requires 10 mA current consumption.
Q: Can the 2085-ECR be used in hazardous locations?
A: The module supports operation in Class I, Division 2, Groups A, B, C, and D hazardous locations when installed according to applicable system requirements.
Field Installation Guidelines
- Install the 2085-ECR only on the final Micro800 Expansion I/O module in the expansion assembly.
- Verify that the expansion modules are fully seated and mechanically aligned before fitting the bus terminator.
- Maintain proper control panel grounding and follow industrial wiring separation practices for communication and power conductors.
- Avoid routing the expansion communication wiring parallel to high-current switching conductors where electrical interference may occur.
- Confirm environmental conditions remain within the specified operating temperature range before system commissioning.
- Use the module only within the supported Micro800 system configuration and applicable hazardous location installation requirements.
