1794-APBDPV1 | Allen-Bradley Flex I/O PROFIBUS Communications Adapter - Petro Auto Tech

Product Overview

The 1794-APBDPV1 is an Allen-Bradley Flex I/O PROFIBUS Communications Adapter from the Flex I/O 1794 product line. This module enables seamless integration of Flex I/O modules into PROFIBUS networks, making it a critical link for distributed control systems. Designed for reliability, it supports up to 8 I/O modules and delivers communication rates up to 12 Mbits.

Technical Specifications Analysis

The 1794-APBDPV1 operates at a nominal input voltage of 24V DC and draws a maximum input current of 385mA. Its inrush current is 23A for 2 ms. The adapter provides a Flexbus current of 640mA max. and has a power dissipation of 4.2W at 19.2V DC, with thermal dissipation of 14 BTU/hr. at the same voltage. Communication uses a Sandard Drop PROFIBUS cable and a 9-pin D-shell connector. The unit weighs 0.31 lbs (0.14 kg).

Application Scenarios & Usage Methods

This adapter is ideal for factory automation systems requiring high-speed data exchange between PROFIBUS controllers and remote I/O racks. Use it in material handling, packaging lines, or process control to connect sensors and actuators. The 1794-APBDPV1 supports up to 8 modules, allowing flexible configuration. For best performance, match the communication rate to your network topology and use Sandard Drop PROFIBUS cable as specified.

Installation Guide & Packing List

Mount the adapter on a DIN rail or wall. Ensure proper grounding using a zinc-plated yellow-chromate steel DIN rail. Keep total power connection wire under 10 meters and avoid wiring two conductors to a single terminal. The package includes the 1794-APBDPV1 adapter module only. Additional items like GSD files are required for configuration and can be downloaded from the manufacturer.

Purchasing Advice

Verify your system voltage matches the 24V DC nominal input and that your PROFIBUS network supports up to 12 Mbits. The 1794-APBDPV1 is a reliable choice for expanding I/O capacity in existing Flex I/O systems. Petro Auto Tech stocks this part with fast shipping and expert support to help you select the right components.

Repair & Maintenance Tips

Periodically inspect the 9-pin D-shell connector for damage or corrosion. Keep the adapter clean and dry, avoiding exposure to condensation. Store within specified environmental limits. Check Flexbus current draw does not exceed 640mA max. to prevent overload. Replace the module if status indicators show persistent faults.
