製品紹介
The Allen Bradley 1734-EPAC Point I/O AC Expansion Power Supply is an AC-powered expansion module designed for use within the POINT I/O distributed control system developed by Rockwell Automation. It is specifically engineered to extend field-side power capacity and maintain stable backplane power when additional I/O modules are introduced into the system.
In modular automation architectures, power distribution becomes a critical factor as the number / connected modules increases. The 1734-EPAC provides a reliable way to segment and reinforce power supply sections, ensuring that downstream modules receive consistent voltage without overloading the primary power source. This makes it particularly useful in large or expanding systems where scalability is required.
The module adopts an open-style design and supports DIN rail installation, allowing for fast integration into standard industrial control cabinets. Its compact footprint and straightforward wiring make it suitable for both new installations and retr/it projects.
