Allen-Bradley | 1734-EP24DC | POINT I/O

Product Description: Allen-Bradley 1734-EP24DC

The Allen-Bradley 1734-EP24DC is a 24V DC expansion power supply module designed for the POINT I/O system. It extends the backplane bus power and creates a new field voltage partition for I/O modules to the right of the unit. This module is essential for applications requiring separation of field power between input and output modules or between analog and digital modules, providing functional and logical partitioning within the I/O system.
