Allen-Bradley 1792D-16BVT0D ArmorBlock MaXum 16-Input DeviceNet Module

What Is the Allen-Bradley 1792D-16BVT0D?

When you need reliable distributed I/O in demanding factory-floor environments, the Allen-Bradley 1792D-16BVT0D ArmorBlock MaXum module delivers. This 16-input, 24VDC DeviceNet node mounts directly on machinery without an enclosure, thanks to its IP67 protection rating. It supports both PNP and NPN sensors, making it flexible for various automation setups. Built for near-machine applications, it reduces wiring and cabinet space while providing real-time I/O updates over the DeviceNet network.

Technical Specifications Breakdown

The 1792D-16BVT0D offers sixteen inputs per block, compatible with 3-wire or dry contact PNP/NPN devices, or eight 4-wire PNP/NPN devices. Its on-state voltage range spans 10.0 to 25.0 VDC, with an on-state current range of 2 mA to 10 mA. The module operates in ambient temperatures from -25 to 60 degrees Celsius and stores safely from -25 to 80 degrees Celsius. Relative humidity tolerance is 5% to 100% non-condensing. Communication rates vary by cable type: 125 Kbps at 500 meters (thick cable) or 375 meters (flat media), 250 Kbps at 200 meters or 150 meters, and 500 Kbps at 100 meters or 75 meters. The module draws a maximum DeviceNet voltage of 200 mA. Status indicators include Net/Mod Status (red/green), Logic Status (red/green), and Point LED (yellow/orange/red). Connectors use M12/Micro style seals.

Industry Applications

This module excels in automotive assembly lines where sensors must be placed close to actuators. For example, on a robotic welding cell, the 1792D-16BVT0D mounts directly on the machine frame, collecting proximity sensor data and sending it via DeviceNet to the PLC. Its IP67 rating withstands coolant splashes and metal shavings. In packaging facilities, the module handles dry contact sensors for conveyor position feedback, eliminating long cable runs and simplifying troubleshooting with its built-in point-level diagnostics.

Installation & Setup Guidance

Mount the 1792D-16BVT0D directly on the machine using the provided mounting holes. Use a cable case for network and power connections, and ensure electronically protected outputs are employed. The M12/Micro style connectors come sealed for IP67 integrity. Connect 3-wire or dry contact PNP/NPN sensors to the input terminals. For 4-wire devices, use eight inputs per block. Set the DeviceNet baud rate via the network scanner; the module auto-detects the configured rate. Verify the ambient temperature stays within -25 to 60 degrees Celsius during operation.

Maintenance & Reliability

Regularly inspect the M12 connectors for damage or moisture ingress to maintain IP67 protection. Check the status LEDs—Net/Mod Status and Logic Status—for any red indications that signal network or logic faults. The module’s diagnostic capabilities include short circuit and open wire detection at the point level, which helps identify sensor failures quickly. Keep the ambient environment within the specified temperature and humidity ranges to ensure long service life. No internal cleaning or disassembly is required; simply verify proper operation periodically.

Compatibility & Integration

The 1792D-16BVT0D integrates seamlessly with Allen-Bradley PLC and SLC programmable controllers through DeviceNet scanners. It functions as a distributed I/O node, updating input status over the DeviceNet network. The module supports both sinking and sourcing input configurations, making it compatible with a wide range of sensors. For systems using thick cable, the communication rate reaches 500 Kbps at 100 meters, while flat media supports up to 75 meters at the same rate. This flexibility allows integration into existing DeviceNet architectures without major redesign.

Buying Guide & Purchasing Advice

Before purchasing the 1792D-16BVT0D, verify your network requirements: DeviceNet baud rate and cable type (thick or flat media). Ensure your sensors match the on-state voltage range of 10-25 VDC and current range of 2-10 mA. The module weighs 1.19 lbs (0.54 kg) and meets IP67 enclosure standards.
