Allen-Bradley 1734-EPAC POINT I/O Expansion Power Supply

Product Overview

The Allen-Bradley 1734-EPAC is a POINT I/O Expansion Power Supply. It provides field power to I/O modules. This unit works with 120 or 240 Volts AC. It supports 4 to 17 modules. The exact number depends on DIN-rail position and current needs.

You can use multiple 1734-EPAC units with POINT I/O adapters. This builds a complete system. The power supply separates field power. It creates logical partitions between input and output modules. This groups modules by function.

Application Scenarios

Use this power supply in industrial automation. It works with Allen-Bradley POINT I/O systems. Common applications include manufacturing lines. It also works in process control. The unit powers sensors and actuators. It ensures stable field voltage.

Separate power sections for safety. Group output modules away from input modules. This reduces electrical noise. The 1734-EPAC works in cabinets or panels. It fits standard DIN rails.
