Information About 1734-EP24DC

The 1734-EP24DC is part of the POINT I/O platform and delivers supplemental 24 VDC power to extend the number of modules supported in a POINT I/O segment. It accepts 10–28.8 VDC input and provides up to 1 A of output current, with the POINTBus receiving 400 mA for powering backplane functions. The module operates from –20 to 55 °C, mounts on a DIN rail, and separates field power from control power to prevent overload on upstream modules. With global certifications including UL, CE, CUL, KC, Marine, GOST, and C-TICK, the 1734-EP24DC integrates reliably into distributed control panels and industrial automation systems.

Key Features:

  • Expansion Power for POINT I/O: Supplies isolated 24 VDC field-side power to extend POINT I/O module chains.
  • Wide Input Voltage Range: Accepts 10–28.8 VDC, supporting flexibility in industrial power distribution systems.
  • 1 Amp Output Capacity: Provides sufficient power for multiple downstream modules while delivering 400 mA to the POINTBus.
  • Power Isolation: Separates field-side and backplane power to protect upstream modules from overloads or wiring faults.
  • DIN-Rail Mountable: Installs quickly into cabinet environments using standard DIN rail hardware.
  • Industrial Temperature Operation: Functions reliably between –20 and 55 °C for use in harsh automation conditions.
  • Open-Style Design: Integrates easily into existing POINT I/O structures without requiring additional enclosure components.
  • Certified for Global Use: Meets UL, CE, CUL, KC, Marine, GOST, and C-TICK industrial standards.

The 1734-EP24DC delivers the reliability and precision required for extending POINT I/O power capacity in distributed industrial systems.

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. Its availability ensures reliable power extension within a distributed I/O network. Customers can confidently use this module knowing it is part of the actively supported product line.
