Allen Bradley 1734-EP24DC Power Bus Extension Module

The AB 1734-EP24DC is a POINT I/O power bus extension module designed to extend both the backplane and field-side power for additional POINT I/O modules in distributed systems. Operating at 24V DC with up to 1.3 A output current, this module is ideal for segmenting large I/O configurations, improving system stability, and ensuring voltage isolation between expansion banks.

It supports seamless integration with POINT I/O terminal bases and allows for strategic power distribution within high-density modular I/O architectures.
