Product Introduction
The Allen Bradley 1734-EP24DC Point I/O DC Expansion Power Supply is a dedicated expansion power module designed for the POINT I/O distributed I/O platform from Rockwell Automation. It is used to extend the available field-side power capacity when additional I/O modules are added to a POINT I/O system.
In practical industrial installations, a single power supply may not be sufficient to support a growing number of I/O modules. The 1734-EP24DC addresses this limitation by providing a convenient way to segment and boost field power without redesigning the entire system. It ensures stable voltage distribution and isolates power sections, improving overall system reliability.
Engineered for DIN rail mounting, this module integrates seamlessly into compact control panels and supports quick installation and replacement. Its robust design makes it suitable for demanding environments where consistent power delivery is critical for system performance.
