Product Overview
Is your control panel short on I/O points but long on space constraints? The Allen-Bradley 1794-IB10XOB6 solves that problem. It is a digital combination I/O module in the Flex I/O 1794 series. This single module packs 10 current sink inputs and 6 current source outputs into one compact unit. Both sides run on a nominal 24 VDC. That mix lets you handle sensing and switching tasks without adding separate input and output cards. For system integrators and maintenance teams, fewer modules mean simpler wiring, smaller panels, and lower spare-part counts.
Technical Specifications
Inputs That Handle Real Field Signals
The 1794-IB10XOB6 provides 10 current sink inputs. Each input draws a nominal on-state current of 8 mA at 24 VDC. The nominal input impedance is 4.8 kilohms. In practice, this means standard 24 VDC sensors and switches drive the inputs directly. The 8 mA draw keeps load on field devices low, which suits proximity sensors and pushbuttons.
Outputs Built for Control Duty
Six current source outputs handle the switching side. Each channel carries a nominal on-state output current of 2 A per channel at 24 VDC. That 2 A rating lets you drive relays, small solenoids, and indicator lamps without an interposing relay in many cases.
System and Environmental Limits
The module draws 50 mA from the Flexbus. This matters when you calculate backplane power budget for your Flex I/O adapter. The operating temperature range is -20°C to 55°C. Note that this unit has no IP rating; it is open. It belongs inside a protective enclosure, not in washdown or dusty open-air locations.
Buyer’s Guide: Is This Module Right for You?
Before you order the 1794-IB10XOB6, run through this checklist.
Count your points. Do you need roughly 10 inputs and 6 outputs in one slot? If your mix is very different, a dedicated input or output module may fit better.
Check your sensor type. The inputs are current sink. Confirm your field devices match this configuration.
Check your load current. Each output is rated 2 A per channel. Add up the current for every connected load and stay within this limit.
Plan for the enclosure. With no IP rating, the module needs a clean, protected cabinet. Verify your panel meets the -20°C to 55°C operating range.
Confirm the series. This module belongs to the Flex I/O 1794 family. Verify your adapter and mounting hardware match that series.

Installation and Setup
Flex I/O systems mount on a DIN rail or panel with a compatible adapter. Follow the manufacturer’s installation guide for terminal base wiring and module seating. Keep input and output wiring separated where possible to reduce noise on the 8 mA input circuits. Because the unit is open, install it inside an enclosure that keeps out dust and moisture. Do not exceed the 2 A per channel output rating, and verify the 50 mA Flexbus load against your adapter’s power budget before power-up.
Maintenance and Reliability
These modules have no moving parts, so wear is minimal. Focus on the environment instead. Heat is the main enemy. Keep cabinet temperature within the -20°C to 55°C range and ensure adequate airflow. Inspect terminal connections periodically for looseness or corrosion. Check output loads for shorts that could stress the 2 A channels. Keep spare modules on hand; a failed I/O point can stop a line, and a quick swap keeps downtime short.
Compatibility and Integration
The 1794-IB10XOB6 integrates with Flex I/O 1794 series adapters and terminal bases. It communicates over the Flexbus, drawing 50 mA. Confirm your adapter supports the combination module layout you plan to use. Because the data does not list specific communication protocols, verify network compatibility with your adapter documentation before purchase.
