Information About 1734-EP24DC

The Allen-Bradley 1734-EP24DC Power supply expansion unit passes the 24V DC electric field to the I/O module on the right side. This power supply expansion unit extends the backplane bus power up to 17 I/O modules on the right side of the supply. This power supply creates a new field voltage partition segment for the field drive device. The 1734-EP24DC separates field power from the I/O module to the left of the unit.

This power supply is dark gray, and the dark gray color of the expansion power supply enables easy visual inspection and identification. You can use a power supply expansion unit with a POINT I/O adapter to assemble the system in full. The 1734-EP24DC expansion unit is compatible with 1734 POINT I/O adapters.

The supply voltage range of the 1734-EP24DC is from 10-28.8V DC. The maximum supply current of this power supply is 10A. The operating temperature of this power supply is -13-140 deg. Fahrenheit and the nonoperating temperature is -40-185 deg. Fahrenheit at a relative humidity of 5-95% without condensation. The operating vibration of this power supply is 5g at 10-500 Hz. The operating shock of the 1734-EP24DC is 30g and the nonoperating shock is 50g. It has 24 Volts DC Field Power and an Inrush Current of 6 amps for 10 milliseconds with Reverse Polarity Overvoltage Protection. This Expansion Power Supply has 10 amps Power Supply Current.

The 1734-EP24DC is an Allen-Bradley module that functions as an expansion power supply. This module is designed for use with the 1734 POINT I/O system. It is mainly used to extend the POINTBus current and supply power to modules installed at the right side of the power supply.

The 1734-EP24DC supports installation of up to Four (4) to Seventeen (17) POINT I/O modules, depending on the current rating of the installed module. It has an input voltage rating of 24VDC, nominal with acceptable voltage range of 10-28.8 VDC. This expansion power supply is capable of withstanding an inrush current of 6 Amperes for 10 ms.

The 1734-EP24DC has a built-in status indicator such as field power status indicator and 5V system power indicator. It may be installed horizontally and vertically, following the orientation of the POINT I/O system. When installed horizontally, the POINTBus output current are 1 A @ 10-19.2VDC input and 1.3 A @ 19.2-28.8VDC input. When installed vertically, the POINTBus output current is 1 A @ 10-28.8V input. This module has an integral input overvoltage protection, specifically, reverse polarity protection.

The 1734-EP24DC is compatible for installation with any 1734 POINT I/O adapters. When the expansion power supply is interrupted, the output voltage stays within the specification when input supply voltage drops out for 10 ms at 10V maximum load.

The 1734-EP24DC has a maximum power consumption of 9.8 W @ 28.8V DC and maximum power dissipation of 3.0 W @ 28.8V DC and Thermal Dissipation of 10.0 BTU/hr @ 28.8V DC.

Frequently Asked Questions about 1734-EP24DC
Question: What is the 1734-EP24DC, and what are its main functions?
Date Update:02/06/2025
Answer:

The 1734-EP24DC is a POINT I/O expansion power supply module designed to extend power within a POINT I/O system. It supplies power to additional I/O modules to the right of its installation point. This allows for larger and more complex distributed I/O configurations without exceeding power supply limitations. The module supports up to 17 modules depending on the system configuration. Its compact design makes it easy to install in industrial control panels.

Question: How much current can the 1734-EP24DC module supply?
Date Update:02/06/2025
Answer:

The module provides different output currents depending on mounting orientation. For horizontal mounting, it delivers 1 A at 10–19.2V and 1.3 A at 19.2–28.8V. For vertical mounting, it supplies 1 A at 10–28.8V. These output current ratings ensure that connected I/O modules receive adequate power. Proper configuration and load calculation are important to avoid exceeding the module’s capacity. This helps maintain system stability and prevents power-related faults.

Question: What is the maximum power consumption and power dissipation of the 1734-EP24DC?
Date Update:02/06/2025
Answer:

The module has a maximum power consumption of 9.8 Watts at 28.8V DC. It dissipates a maximum of 3 Watts under full load conditions. These ratings ensure that the module operates within safe thermal limits. Additionally, the module’s thermal dissipation is 10 BTU/hour, which helps engineers design appropriate cabinet cooling solutions. Understanding these values helps in planning the power and thermal requirements of the control system.

Question: What are the key benefits of using the 1734-EP24DC module in a POINT I/O system?
Date Update:02/06/2025
Answer:

The 1734-EP24DC module offers several advantages that enhance system performance and design flexibility. Key benefits include:

  • Allows for the expansion of POINTBus power, supporting up to 17 additional I/O modules.
  • Provides built-in overvoltage and reverse polarity protection for safe and reliable operation.
  • Features status indicators to aid in quick diagnostics and system monitoring.
  • Offers compact design and flexible mounting options to fit various control panel configurations.

These benefits make the 1734-EP24DC a valuable addition to any POINT I/O system, supporting efficient and reliable industrial automation.

Question: Is the 1734-EP24DC module still in production?
Date Update:02/06/2025
Answer:

Yes, the 1734-EP24DC module is currently active and supported by Rockwell Automation. This means it can be readily integrated into new or existing POINT I/O systems.
