Industry Trends in Modular I/O Power Solutions
As factories adopt distributed control architectures, the demand for modular I/O systems that can scale with production lines continues to grow. Engineers often face challenges when adding I/O modules beyond the initial backplane power limit, which can disrupt system performance and increase downtime. The Allen-Bradley 1734-EP24DC addresses this need by providing a dedicated expansion power supply that extends the POINTBus current to additional modules.
Introducing the 1734-EP24DC Expansion Power Supply
Part of the POINT I/O series from Rockwell Automation, the 1734-EP24DC is an expansion power supply module designed to pass 24V DC field power to I/O modules on the right side. It supports installation of four to seventeen modules, depending on the current requirements of each module. This unit creates a new field voltage partition segment, separating field power from the I/O module to its left for improved system organization.
Technical Specifications Analysis
The 1734-EP24DC operates with a nominal input voltage of 24V DC and accepts a voltage range of 10 to 28.8V DC. It provides a POINTBus output current of 1 A at 10 to 19.2V input and 1.3 A at 19.2 to 28.8V input for horizontal mounting, while vertical mounting supports 1 A across the full 10 to 28.8V input range. The module has a power consumption of 9.8 Watts and a power dissipation of 3 Watts, with a thermal dissipation rating of 10 BTU per hour.
Application Scenarios and Use Cases
In manufacturing environments where I/O modules are distributed across long conveyor lines, the 1734-EP24DC ensures reliable power delivery to remote modules without overloading the main backplane. It is also suitable for applications requiring mixed mounting orientations, as it supports both horizontal and vertical installation. The reverse polarity overvoltage protection adds a layer of safety for field wiring.
Compatibility and Integration
The 1734-EP24DC is compatible with all 1734 POINT I/O adapters, allowing seamless integration into existing Rockwell Automation systems. It can be used with any 1734 series I/O modules to extend the bus power and create new field power segments. This compatibility simplifies system expansion and reduces the need for additional power supplies.
