ArmorBlock OB16M12R: 16-Point Sourcing Output Module with Integrated M12 Cordsets

Technical Specifications

Main Features and Advantages

Extreme Environmental Protection and On-Machine Design: The core advantage of the Allen-Bradley 1732E-OB16M12R​ is its ability to operate reliably in the harshest locations. Its IP67-rated, sealed metal and composite housing eliminates the need for a protective enclosure, allowing it to be mounted directly on machine frames, inside washdown areas, or near processes that generate dust, oils, and moisture. This on-machine placement dramatically reduces cabinet size, panel cost, and the volume of conduit and wire needed, as only a network cable and power cable need to be routed to the module, not individual wires for all 16 outputs. The integrated, color-coded M12 output connectors provide a quick, secure, and sealed interface to field devices, significantly speeding up machine assembly, commissioning, and maintenance.High-Density, High-Current Outputs with Advanced Diagnostics: The module packs 16 high-capacity sourcing outputs into a compact form factor, with each channel capable of switching up to 2A. This makes it perfect for directly driving valve manifold solenoids, pilot lights, and other actuators without the need for intermediate relays. The Allen-Bradley 1732E-OB16M12R​ is equipped with comprehensive diagnostics accessible over the EtherNet/IP network. The module and its controller can monitor for faults such as short-circuit, overload, and open-wire conditions on each channel. Bright, per-point LED indicators provide instant visual status at the device. Furthermore, its integrated two-port Ethernet switch enables linear “daisy-chain” network topologies, reducing cabling and switch port requirements. This combination of ruggedness, high performance, and intelligent diagnostics makes the 1732E-OB16M12R​ a superior solution for building reliable, maintainable, and cost-effective distributed control architectures.

Application Field

The Allen-Bradley 1732E-OB16M12R​ is purpose-built for applications requiring robust, distributed control in challenging environments, particularly where devices are spread out across a machine or production line. A quintessential application is controlling pneumatic or hydraulic valve manifolds on automated machinery. The module can be mounted directly on or adjacent to the valve bank, with each of its 16 outputs connected via a short M12 cordset to a solenoid valve. This is common in packaging machines, assembly stations, and material handling systems, drastically simplifying wiring and improving serviceability. In the food, beverage, and pharmaceutical industries, where high-pressure washdowns with caustic chemicals are routine, the IP67 rating of the 1732E-OB16M12R​ makes it ideal for installation on filling machines, mixers, and conveyors, eliminating corrosion-prone control cabinets in the processing area.In automotive manufacturing, the module is used for controlling tooling clamps, welder guns, and glue applicators on robotic cells and transfer lines. Its rugged design withstands the vibration, weld spatter, and coolants typical in these environments. The Allen-Bradley 1732E-OB16M12R​ is also extensively used in material handling for controlling diverters, stoppers, and singulators on conveyor systems, where its distributed nature allows for control segments to be added or modified easily. Any application that benefits from placing the I/O point close to the actuator to reduce wiring, improve diagnostics, and withstand dirt, moisture, or washdown is an ideal candidate for the 1732E-OB16M12R, enabling cleaner, more modular, and more reliable machine designs.
