2085-IQ32T | Allen-Bradley Micro850 32-Point DC Digital Input Module

Product Overview

The Allen-Bradley 2085-IQ32T serves as a high-density expansion interface for the Micro850 and Micro870 programmable logic controller families. This module significantly expands the system capacity by providing 32 discrete input points in a single expansion slot. It supports both sinking and sourcing wiring configurations, offering maximum flexibility for interfacing with a wide range of industrial sensors and switches. We supply this unit as 100% Brand New and Original, ensuring your automation architecture utilizes factory-tested, high-reliability hardware with zero prior field cycles.

Technical Specifications

Engineering Advantages

• High-Density Space Optimization: The 2085-IQ32T packs 32 input channels into a slim form factor. This density allows for massive I/O expansion without requiring additional chassis or large enclosures, effectively solving the problem of limited DIN rail space in complex control panels.

• Universal Input Versatility: The internal circuitry accommodates both 24V DC (Sink or Source) and 24V AC (50/60 Hz) signals. This flexibility enables engineers to consolidate different signal types onto a single module, reducing the overall bill of materials and simplifying inventory management.

• Instantaneous Diagnostics: 32 dedicated yellow LED indicators provide real-time status for every input channel. Maintenance technicians can identify failed field devices or wiring breaks at a glance, bypassing the need for a laptop connection during initial hardware troubleshooting.

• Rigid Backplane Integration: The module snaps securely onto the Micro800 expansion bus. This direct connection ensures high-speed data throughput and vibration resistance, preventing the intermittent signal drops often found in modular systems with weaker interlocking mechanisms.

FAQs

Q: Does the 2085-IQ32T require a separate terminal block?

A: Yes. High-density modules like the 2085-IQ32T typically utilize specific terminal block headers to manage the 32-point wiring. Ensure you select the correct compatible terminal block for the 2085 series to facilitate secure and organized field wiring.

Q: Can I use this module with a Micro820 controller?

A: No. The 2085-IQ32T expansion module only supports the Micro850 and Micro870 PLC families. The Micro820 uses 2080-series "Plug-in" modules that insert directly into the controller front, rather than the "Expansion" modules that mount to the right side of the CPU.

Q: Is this unit "New Surplus" or "Brand New"?

A: We guarantee this 2085-IQ32T is 100% Brand New and Original. It arrives in its original factory-sealed Allen-Bradley packaging. This ensures the optoisolators and internal semiconductors have never experienced thermal stress, providing the maximum possible service life for your application.

Q: What happens if the leakage current of my sensor exceeds 1.2 mA?

A: The module defines 1.2 mA as the maximum off-state current. If your sensor’s leakage current exceeds this value, the input may stay in the "ON" state erroneously. To prevent this, you must add a bleed resistor across the input to shunt the excess leakage current to ground.
