Applying Allen Bradley 2085-OB16 as a high-density DC source output expansion module in a Micro800 control architecture
Industrial buyers searching for Allen Bradley 2085-OB16 usually need three things at the same time: correct product identity, usable technical parameters and a clear boundary around configuration-dependent options. This corrected page addresses those points without repeating administrative tables.
Where this output module fits
Allen Bradley 2085-OB16 is identified here as a Micro800 16-point DC source transistor output expansion module. This module adds sixteen solid-state DC source outputs to a compatible Micro800 controller. It is intended for compact machine-control panels where output density, repeatable transistor switching and a clear expansion-bus architecture matter more than relay isolation.
2085-OB16 technical profile
The following table gives the relevant technical profile for Allen Bradley 2085-OB16. It appears once on this page and separates confirmed family data from configuration-dependent details.
| Exact product reference | Allen Bradley 2085-OB16 |
| Product type | Micro800 16-point DC source transistor output expansion module |
| Catalog number | 2085-OB16 |
| I/O class | Discrete output expansion module |
| Output count | 16 points |
| Output technology | Source transistor outputs |
| Field voltage | 12/24 V DC |
| Platform context | Micro850 and Micro870 expansion I/O |
Key characteristics follow Rockwell Automation Micro800 expansion I/O documentation; detailed load-current, surge and derating limits should be checked in publication 2085-IN003 or the current technical data.
Source-output wiring checkpoints
Installation planning for Allen Bradley 2085-OB16 should protect the existing wiring, process and configuration evidence. Before installation, isolate power, compare source-versus-sink logic, confirm common polarity and check the expansion-bus position. If this is the final 2085 expansion module, the system layout must retain the required bus terminator in the final position.
Loads and machine functions
Application review for Allen Bradley 2085-OB16 should start with the actual process or machine duty. Typical loads include interposing relays, indicators, small DC solenoids and other 12/24 VDC devices whose current and inrush remain within the module and point limits stated in the installation data. The field supply arrangement and common wiring must be reviewed before replacing a sink-output or relay-output module.
Avoiding sink/source replacement errors
Compatibility for Allen Bradley 2085-OB16 must be established by function and configuration, not enclosure appearance. Do not substitute 2085-OV16 merely because it also has sixteen DC outputs: 2085-OV16 is a sink transistor module, while this catalog number is the source-output version. Firmware, controller support and field wiring should be checked against the installed Micro850 or Micro870 project.

Information for a comparable quotation
To obtain a technically comparable offer for Allen Bradley 2085-OB16, the inquiry should go beyond price and availability. A useful quotation identifies the controller catalog number, available expansion position, field voltage, load type, per-point current, simultaneous-load demand and the required terminal accessories. Buyers should also state whether the order is for a bare module or a complete replacement package.
- Keep the complete Allen Bradley 2085-OB16 phrase on the quotation and purchase order.
- Ask the supplier to identify inclusions, exclusions and the supporting document revision.
- Resolve technical deviations before order release rather than during receiving inspection.
Nearby Micro800 catalog choices
When alternatives to Allen Bradley 2085-OB16 are discussed, use nearby families only as comparison points. Related Micro800 references include 2085-OV16 for sink outputs, 2085-OW16 for relay outputs and 2085-ECR as the expansion-bus terminator.
Final order review for Allen Bradley 2085-OB16
Before release, compare Allen Bradley 2085-OB16 with the nameplate, current manufacturer data and the installed application. Keep Allen Bradley 2085-OB16 on the RFQ, supplier offer, purchase order and incoming-inspection record so engineering and procurement review the same item.
