1732E-IB16M12R | Allen-Bradley Ethernet/IP ArmorBlock I/O 24V DC, 16 Sink Inputs

This module supports Ethernet/IP, an industry-standard industrial protocol used for real-time control and data acquisition. Ethernet/IP allows the module to connect directly to controllers and other networked devices. It supports features such as CIP messaging, real-time I/O data exchange, and diagnostics. With this communication method, the module integrates seamlessly into ControlLogix, CompactLogix, and other Ethernet/IP-based systems. The dual-port design also supports daisy-chaining and Device Level Ring (DLR) topologies.

The module is designed for on-machine mounting, meaning it is placed directly on equipment or nearby fixtures rather than in control panels. It can also be panel-mounted if required. This on-machine design reduces wiring complexity and improves response time by placing I/O close to field devices. The ArmorBlock's form factor supports flexible placement options. This allows for decentralized control architectures and simpler system design.

The module is rated to operate in temperatures ranging from -20°C to 60°C (-4°F to 140°F). This makes it suitable for both refrigerated and high-temperature industrial environments. The electronics are protected against thermal stress and are tested for reliable performance. Adequate ventilation and spacing must still be considered during installation. This rating ensures the module’s durability across various sectors.

The exact dimensions of the 1732E-IB16M12R module are not always explicitly stated in product briefs, but it follows the typical ArmorBlock compact footprint of approximately 210 mm x 60 mm x 35 mm (8.3 x 2.4 x 1.4 inches). This slim profile makes it easy to mount directly on machines, even in tight spaces. The low-profile body helps minimize cable clutter and promotes neat installations. Despite its small size, the module accommodates 16 M12 connectors for efficient signal handling. Its design balances size, durability, and functionality.

Yes, the 1732E-IB16M12R is an actively supported and currently manufactured product in the Allen-Bradley ArmorBlock family. It is part of Rockwell Automation’s modern on-machine distributed I/O solutions for Ethernet/IP systems. The module remains available through authorized distributors and is recommended for both new installations and upgrades. Its continued support ensures access to firmware updates and accessories. The product is not listed as obsolete or discontinued.
