Get now the 2080-IF2, a compact 2-channel analog input plug-in module designed to expand the capabilities of Allen-Bradley Micro800 controllers. This module is the perfect solution for adding low-cost, high-precision analog sensing to your Micro810, Micro820, Micro830, or Micro850 PLC system without increasing the footprint.
What Is the 2080-IF2?
The 2080-IF2 is a non-isolated analog input module that belongs to the Micro800 «Plug-in» family. These modules are unique because they snap directly into the front of the controller, allowing for highly customized hardware configurations while keeping the PLC’s physical dimensions unchanged. The 2080-IF2 provides two channels of 0-10V voltage input, which are commonly used for reading signals from sensors such as temperature transmitters, pressure transducers, or potentiometers. Its 12-bit resolution provides sufficient precision for most small-to-medium scale automation tasks, such as pump control, HVAC monitoring, and simple process loops. Its architecture is streamlined for the Connected Components Workbench (CCW) software, making configuration and scaling a matter of a few clicks.

Architecture and Plug-in Flexibility
The Micro800 architecture’s plug-in design is a major advantage for machine builders. By using the 2080-IF2, you can add analog functionality only when needed, avoiding the cost of a full-sized expansion module. The module shares the controller’s internal bus for both power and communication. Once inserted, it is automatically recognized by the firmware. This modularity allows for «right-sizing» the hardware for the specific application, making it a cost-effective choice for OEM equipment. The 2080-IF2 is particularly useful in applications where a Micro810 or Micro820 needs to monitor a small number of analog variables alongside its standard digital I/O.
Maintenance Tips
Because the 2080-IF2 is non-isolated, it is critical to ensure that all analog devices share a common ground with the controller to prevent signal inaccuracies or damage to the module from ground potential differences. Periodically check the plug-in seating; if the PLC experiences intermittent «Module Missing» faults, reseat the module in its slot. To protect the 12-bit accuracy, always use shielded twisted-pair cables for the 0-10V signals and ground the shield at the PLC’s ground terminal to minimize electromagnetic noise pickup.
Frequently Asked Questions
Q: Can the 2080-IF2 read 4-20mA current signals?
A: No, the 2080-IF2 is strictly for 0-10V signals. To read 4-20mA signals, you would need the 2080-IF4 module or use an external 500-ohm precision resistor to convert the current to voltage.
Q: How many 2080-IF2 modules can I add to a Micro850?
A: A Micro850 can support up to 5 plug-in modules, meaning you could add up to 10 analog input channels using 2080-IF2 modules, provided you have available plug-in slots.
