Allen-Bradley 1734-EP24DC Point IO Extension Power Module

Description:

The Allen-Bradley 1734-EP24DC POINT I/O Extension Power Module is used in distributed I/O systems to extend and isolate field power and POINTBus power for additional POINT I/O modules within an automation network. Commonly installed in manufacturing systems, process control applications, packaging equipment, material handling systems, and machine automation platforms utilizing Allen-Bradley POINT I/O architecture. Maintenance teams and system integrators use this module for system expansion, retrofit, or replacement projects to increase I/O capacity while maintaining reliable power distribution and segmentation within the control system.

Applications:

The Allen-Bradley 1734-EP24DC is commonly used in distributed control systems, PLC-based automation networks, conveyor systems, packaging machinery, process plants, and OEM machine control panels. The module provides 24VDC field power and extends the POINTBus to support additional I/O modules beyond the power limitations of a single segment. It also electrically separates power segments to improve system design flexibility and reliability in large-scale automation installations.
