Allen-Bradley 1792D-8BIO8E ArmorBlock MaXum I/O Module, 24V DC

Are unreliable field I/O connections costing you production downtime?

In harsh industrial environments, maintaining robust and noise-immune I/O connections is critical. The Allen-Bradley 1792D-8BIO8E ArmorBlock MaXum I/O module provides a rugged, standalone solution for discrete control applications.

Product Overview

The 1792D-8BIO8E module is a standalone 24 Volts DC I/O module from the Allen-Bradley ArmorBlock MaXum product line. It supports the DeviceNet network and comes with 16 channels, broken down into 8 input channels and 8 output channels. The input channels feature 24 Volts DC sinking voltage, while the outputs are self-protected 24 Volts DC outputs providing a maximum of 0.3 Amps of current each. The connector features a single input and a single output. The unit's output power is obtained internally from the DeviceNet power. The inputs and outputs provide users with short-circuit protection with notifications on the block level. Local logic control is added to the 1792D-8BIO8E module. It has been manufactured and tested to meet the Council Directive 89/336/EEC Standard for electromagnetic compatibility. The module also meets the EN 50081-1 EMC Generic Emission Standard (Part 2) for industrial environments and the EN 50082-2 EMC Generic Immunity Standard.

Technical Specifications Breakdown

Key parameters for the 1792D-8BIO8E are listed below for quick reference:

Industry Applications

For example, in packaging machinery, the 8 input channels can monitor proximity sensors while the 8 output channels control solenoid valves. The DeviceNet connectivity simplifies wiring and diagnostics, reducing installation costs. In material handling systems, the short-circuit protection and loopback connections enhance reliability by minimizing noise disturbances and preventing damage from wiring faults.

Installation & Setup Guidance

When installing the 1792D-8BIO8E module, ensure all connectors and caps are securely tightened to maintain proper sealing and protect against leaks. The module is prone to noise disturbances, so technicians must ensure input and output cables are properly terminated. With inputs and outputs connected in loopback formations, the return wires must be connected back together to maximize noise immunity, which is essential for achieving desired output performance. The module I/O exchanges with the master device via polled, change of state, or cyclic connection. The cyclic connection allows configuration as a Client I/O, where the module produces its I/O cyclically at the configured rate.

Maintenance & Reliability

Periodically inspect all connectors and caps for tightness and signs of wear. Keep the module free of dust and moisture. Given its ESD sensitivity, handle the module with appropriate ESD precautions during maintenance. Verify that the DeviceNet power supply remains stable within the 24V DC range to ensure consistent output power.

Compatibility & Integration

The 1792D-8BIO8E integrates directly with DeviceNet networks. It supports polled, change of state, and cyclic connection types for flexible data exchange with a master device. The loopback connections simplify wiring and enhance noise immunity. The module is designed for standalone operation, making it suitable for distributed I/O architectures.

Selection Guide & Purchasing Advice

When selecting the 1792D-8BIO8E for your application, confirm that your system uses 24V DC I/O and DeviceNet communication. This module is a reliable choice for applications requiring 8 inputs and 8 outputs with short-circuit protection.

Troubleshooting & Common Issues

If the module does not communicate with the master, check the DeviceNet power supply and cable connections. For output failures, verify that the load current does not exceed 0.3 Amps per output and that short-circuit protection has not been triggered. Input issues may stem from incorrect wiring or noise; ensure loopback connections are properly terminated. If the module indicates a fault, inspect the block-level notification for short-circuit conditions.
