Allen-Bradley 1794-IB10XOB6 FLEX I/O Digital Combination Module

Product Overview

The Allen-Bradley 1794-IB10XOB6 functions as a high-efficiency digital combination module within the FLEX I/O distributed architecture. This single-slot module integrates 10 sinking inputs and 6 sourcing outputs, providing a versatile solution for applications requiring high I/O density in a small footprint. It operates on a 24V DC nominal voltage and bridges the gap between field devices and the industrial network. We supply this unit as 100% Brand New and Original, ensuring your automation system utilizes factory-sealed hardware for mission-critical reliability.

Technical Specifications

Engineering Advantages

• Integrated I/O Hybridization: The 1794-IB10XOB6 combines both input and output functions on a single module. This hybridization allows engineers to handle diverse field devices—such as proximity switches and solenoid valves—without occupying two separate slots on the FLEX I/O backplane, effectively halving the required DIN rail space.

• Optimized Sinking/Sourcing Logic: The module features 10 sinking inputs paired with 6 sourcing outputs. This configuration aligns with standard industrial wiring practices, enabling direct connection to PNP-type sensors and DC-actuated loads without interposing hardware.

• Modular Terminal Base Flexibility: This module docks onto 1794-TB3 or 1794-TB3S terminal bases. The design allows for "Removal and Insertion Under Power" (RIUP), meaning maintenance teams replace the electronic module without disturbing existing field wiring or shutting down the entire rack.

• Enhanced Heat Dissipation: The open-style design and compact internal circuitry minimize thermal buildup. This ensures stable logic execution even when mounted in high-density enclosures where vertical airflow might be restricted.

FAQs

• Q: Which terminal base should I use for the 1794-IB10XOB6?

  A: You must install this module on a 1794-TB3 or 1794-TB3S terminal base. These bases provide the necessary 3-wire termination points required for the 16-point combination of inputs and outputs.

• Q: Can I use this module to switch AC loads?

  A: No. The 1794-IB10XOB6 specifically targets 24V DC applications. Connecting AC voltages to the sourcing outputs or sinking inputs will cause catastrophic failure of the internal solid-state components.

• Q: Does the module require an external power supply for the outputs?

  A: Yes. You must provide an external 24V DC power source to the terminal base to drive the 6 sourcing outputs. The module uses this external power to energize field actuators while drawing only logic power from the FLEX I/O backplane.

• Q: How does the "Sinking Input" logic affect my sensor selection?

  A: Because the inputs are "Sinking," the module provides the path to the common ground. You must use "Sourcing" (PNP) sensors that output a positive 24V DC signal to successfully trigger the input points.
