Purchase now the 2080-IF4, a high-density 4-channel analog input plug-in module specifically engineered to expand the sensing capabilities of Allen-Bradley Micro800 controllers. This compact module is the professional choice for machine builders requiring precise voltage or current data acquisition in a space-optimized footprint.
What Is the 2080-IF4?
The 2080-IF4 is a high-performance analog input expansion module that belongs to the Micro800 Plug-in family. Designed for use with Micro810, Micro820, Micro830, Micro850, and Micro870 controllers, it allows for the addition of four non-isolated analog inputs without increasing the physical width of the PLC. This module supports both 0-10V DC and 0-20mA signals, making it exceptionally versatile for monitoring diverse industrial sensors. Its architecture is built on the Sigma-Delta conversion principle, providing a 12-bit resolution that ensures reliable and stable readings for process variables such as pressure, temperature, flow, and liquid levels. By utilizing the front-facing plug-in slots, the 2080-IF4 streamlines cabinet design and reduces overall system costs.

Industrial Architecture and Scalability
The 2080-IF4 is central to the modular architecture of the Micro800 series. In distributed control systems, it allows for «right-sized» I/O configurations. The module communicates directly with the controller CPU through the internal backplane pins. Within the Connected Components Workbench (CCW) software, the 2080-IF4 is easily configured through a user-friendly interface that handles scaling from raw counts to engineering units, significantly reducing engineering time during the commissioning phase of project development.
Expert Tips
To maintain maximum accuracy with the 2080-IF4, pay close attention to the common-mode voltage. Since the channels are non-isolated, ensure that all field sensors share a stable ground reference with the PLC. If you are experiencing noise in your 0-20mA loops, consider using a shielded twisted-pair cable and ground the shield only at the PLC end to prevent ground loops. In high-density cabinets, place this module in the slot furthest from high-power relays to minimize electromagnetic interference on the sensitive analog-to-digital converters.
Frequently Asked Questions
Q: Does the 2080-IF4 support 4-20mA signals directly?
A: Yes, it supports 0-20mA, which covers the standard 4-20mA range. You can scale the input in the CCW software so that 4mA represents your minimum engineering value.
Q: Can I mix voltage and current inputs on the same module?
A: Yes, each channel is independently configurable in the software, allowing you to use 0-10V on one channel and 4-20mA on another simultaneously.
