Purchase now the 2085-IQ16, a high-performance 16-point digital input module for expanding your industrial control system capacity.
What Is the 2085-IQ16?
The 2085-IQ16 is a versatile 16-channel digital input expansion module designed for the Allen-Bradley Micro850 and Micro870 PLC families. It provides a reliable interface between field devices like pushbuttons, limit switches, and proximity sensors and the controller’s logic. Supporting both sink and source (NPN/PNP) wiring configurations at 24V DC, this module offers the flexibility required for modern industrial environments, ensuring seamless integration into existing control architectures.

System Integration and Performance
As part of the 2085 expansion family, the 2085-IQ16 features a compact design that allows for significant I/O density on a standard DIN rail. The module utilizes optical isolation to protect the sensitive PLC electronics from field-side electrical surges and noise. Its diagnostic LEDs provide immediate visual feedback on the status of each input point, simplifying troubleshooting for maintenance teams during system startups or unexpected downtime.
Maintenance Tips
To ensure long-term reliability of the 2085-IQ16, regularly inspect the Removable Terminal Block (RTB) for tight connections, as thermal cycling in industrial cabinets can loosen screw terminals over time. If a channel fails to trigger, use a multimeter to check the input threshold; the module requires at least 10V DC to register an ‘ON’ state. Keep the module’s ventilation slots clear of dust to maintain optimal operating temperatures.
Frequently Asked Questions
Q: Can I mix Sink and Source devices on the same 2085-IQ16 module?
A: Yes, the 16 inputs are arranged in groups that share a common, allowing you to configure different groups for sink or source depending on your wiring.
Q: What is the purpose of the configurable input filter?
A: The software filter allows you to ‘debounce’ signals from mechanical switches, preventing false triggers caused by contact bounce or electrical noise.
