Allen-Bradley 1794-APB | Flex I/O PROFIBUS Adapter Module

Product Overview

The Allen-Bradley 1794-APB is a PROFIBUS adapter module from the Flex I/O 1794 series, designed to enable high-speed communication between distributed I/O and PROFIBUS master devices. It supports data exchange up to 12 Mbps while offering reliable integration with ControlLogix, CompactLogix, SLC 500, and PLC-5 systems.

This module connects to the Flex I/O system using a 9-pin D-shell PROFIBUS connector and allows up to eight Flex I/O modules to operate on a single adapter. With 24VDC nominal input voltage and a 640 mA backplane current output, the 1794-APB ensures efficient operation for demanding industrial networks.

Key Technical Specifications

Design and Performance

The 1794-APB is engineered for efficient communication and robust network reliability. Its LED indicators provide quick visual diagnostics for both module status and PROFIBUS activity, switching between green and red based on network health.

The module is built for DIN rail or panel mounting, and a highly conductive DIN rail is recommended for proper grounding. With low power consumption of 400 mA and efficient thermal dissipation of 26 BTU/hour, this adapter maintains stable performance under continuous operation.

Industrial Benefits

• Seamless Integration: Connects Flex I/O to PROFIBUS master devices at high speeds.

• High Capacity: Supports up to 8 I/O modules per adapter.

• Strong Reliability: Provides 850 VDC isolation for safe operation.

• Clear Diagnostics: Dual LED indicators simplify troubleshooting and monitoring.

• Efficient Power Use: Consumes minimal energy while delivering strong backplane current.
