Overview
The Allen-Bradley 1760-IB12XOW4IOF is a Pico GFX analog combination I/O module engineered for seamless integration with Allen-Bradley Pico GFX controllers. This compact expansion module bridges discrete digital I/O, analog inputs, and relay control on a single snap-fitted module. Built for applications demanding mixed-signal processing—sensors, analog transducers, and relay load switching—this module delivers proven reliability in industrial automation.
Key Features
- 12 Digital Inputs, 4 Relay Outputs: Comprehensive I/O density in a compact form factor

Typical Applications
The 1760-IB12XOW4IOF excels in compact automation systems requiring mixed I/O types—such as sensor arrays with 4–20 mA or 0–10V analog feedback, relay-switched loads (motors, solenoids, indicators), and high-speed pulse counting (tachometers, encoders). Common deployments include packaging machinery, process control cabinets, legacy system upgrades, and distributed control nodes where space is constrained.
Compatibility & Replacements
This module is designed exclusively for Allen-Bradley Pico and Pico GFX-70 controller series (1760 family). Only one GFX I/O module and one Pico expansion module can be connected per controller. The 1760-IB12XOW4IOF has been discontinued by the manufacturer; however, surplus and refurbished units remain available through authorized distributors. For newer applications, consider alternative Pico expansion modules or modern CompactLogix I/O cards. Verify controller firmware compatibility before field installation.
