Allen-Bradley 1734-EP24DC Power Supply Expansion Module

The Allen-Bradley 1734-EP24DC is a 24V DC expansion power supply module for POINT I/O that extends the backplane power and establishes a separate field-voltage partition to power downstream field devices, enabling configurations that support up to 17 I/O modules depending on current draw. It is designed for DIN-rail mounting in a POINT I/O rack and is installed to the right of the base module, described as an open-style, DIN-mounted expansion accessory. Electrical characteristics include a 24V DC input, approximately 9.8 watts of power consumption, and 50 V continuous isolation between field power and the backplane, helping protect system components. The module provides additional field power to remote I/O locations and is intended to be used in conjunction with adapter-class POINT I/O configurations; installation notes indicate that the 1734-EP24DC (and the 1734-EP24DCK) expansion power supplies are to be used with the appropriate adapter products.
