Global PLC Spare HUB's Insight

The 1734-EP24DC is a strategic necessity for expanding POINT I/O assemblies beyond the power limitations of a standard adapter. In high-density distributed I/O configurations, the backplane current often depletes before the physical slot limit is reached. The 1734-EP24DC solves this by refreshing the POINTBus power and creating a new functional field voltage partition. This "break" in the field power bus allows engineers to mix modules with different voltage requirements or isolate sensitive analog signals from noisy digital loads.

Product Overview

The Allen-Bradley 1734-EP24DC is a dedicated expansion power supply designed for the POINT I/O system. It provides additional POINTBus backplane current (up to 1.3A) and extends the system to support between 4 and 17 additional modules. This module acts as a critical bridge, passing power to the right-side modules while providing reverse polarity protection.

Purchase and Selection Guide

Calculate total POINTBus current draw; if it exceeds adapter capacity, add a 1734-EP24DC.
Use this module to create isolated "Voltage Zones" within a single I/O rack.
Ensure the power supply distance rating is observed for high-current modules.
Verify input voltage stability to stay within the 10-28.8V DC operating window.

Frequently Asked Questions (FAQ)

Does the 1734-EP24DC communicate with the PLC?
No, this is a passive power module. It does not occupy an I/O address or require configuration in software.

What is the difference between this and a 1734-FPD?
The 1734-EP24DC replenishes the 5V logic power, whereas the 1734-FPD only breaks the 24V field power.

Can I use multiple expansion power supplies in one rack?
Yes, you can install multiple units to support large I/O counts up to the node limit.

Will the module protect my PLC from a reversed power connection?
Yes, the integrated reverse polarity protection prevents damage if the DC leads are swapped.

Why is my logic power LED off even though field power is present?
This usually indicates an overload on the POINTBus. Verify that the current draw to the right does not exceed 1.3A.
