Procure now the 2085-IF8, a high-density analog expansion module designed for the Micro850 and Micro870 programmable logic controllers.
What Is the 2085-IF8?
The 2085-IF8 is an advanced 8-channel non-isolated analog input module that significantly expands the data acquisition capabilities of your Allen-Bradley Micro800 system. Engineered by Rockwell Automation, this module allows for the integration of multiple sensors in a single expansion slot, making it ideal for complex industrial processes where space and port density are critical. It supports both voltage and current signals, providing versatile interfacing with transmitters, flow meters, and pressure transducers.

Industrial Architecture and Connectivity
The 2085-IF8 communicates via the high-speed expansion bus of the Micro850/Micro870 family. Each of the eight channels can be independently configured via Connected Components Workbench (CCW) software. This flexibility allows engineers to mix different signal types (e.g., four 4-20mA sensors and four 0-10V sensors) on a single module, reducing hardware costs and cabinet space. Its high-resolution 14-bit converter ensures that even the smallest process fluctuations are captured with precision.
Installation Advice
When installing the 2085-IF8, ensure that signal cables are routed away from high-voltage AC lines to prevent crosstalk. For 4-20mA current loops, we recommend using twisted-pair shielded cables with the shield grounded at only one end to eliminate ground loops that could skew the 14-bit precision readings. Always use the provided 2085-RTB (Removable Terminal Block) to facilitate easy module replacement without rewiring.
Frequently Asked Questions
Q: Does the 2085-IF8 require an external power supply for the analog inputs?
A: The module draws logic power from the backplane, but the analog field-side sensors typically require an external 24V DC power source unless they are self-powered.
Q: Can I use this module with a Micro820 controller?
A: No, the 2085-IF8 is an expansion I/O module compatible only with Micro850 and Micro870 controllers that support the 2085 bus.
