Why Power Distribution Matters in Modular I/O Systems
When expanding a POINT I/O system, engineers often face the challenge of maintaining stable power across multiple modules. Without proper power distribution, voltage drops can cause erratic behavior or system failures. The Allen-Bradley 1734-EP24DC expansion power supply addresses this need by extending the backplane bus power to support up to 17 modules on the right side.
Introducing the 1734-EP24DC Expansion Power Supply
The 1734-EP24DC is a POINT I/O expansion power supply from Allen-Bradley, designed to pass 24V DC field power to adjacent I/O modules. It creates a new field voltage partition segment, separating field power from the module to the left. This dark gray unit enables easy visual identification and is compatible with 1734 POINT I/O adapters.
Key Technical Specifications
The 1734-EP24DC operates with a nominal input voltage of 24V DC and an acceptable range of 10-28.8V DC. It provides a POINTBus output current of 1 A at 10-19.2V input and 1.3 A at 19.2-28.8V input for horizontal mounting, and 1 A at 10-28.8V input for vertical mounting. The module has a power consumption of 9.8 Watts and a power dissipation of 3 Watts, with a thermal dissipation of 10 BTU/hour.
Application Scenarios in Industrial Automation
In manufacturing lines where multiple I/O modules are required, the 1734-EP24DC ensures consistent power delivery to sensors and actuators. It is particularly useful in applications requiring both horizontal and vertical mounting orientations, such as compact control panels. The reverse polarity overvoltage protection adds reliability in harsh industrial environments.
Compatibility and Integration
The 1734-EP24DC is designed for use with the 1734 POINT I/O system and is compatible with any 1734 POINT I/O adapter. It supports installation of four to seventeen modules, depending on the current rating of the installed modules. The module can be mounted horizontally or vertically, following the orientation of the POINT I/O system.
Market Impact and Business Value
By enabling reliable power extension, the 1734-EP24DC reduces the risk of downtime caused by power issues in distributed I/O systems. Its flexible mounting options allow for space-efficient panel designs, potentially lowering installation costs. The module's robust design, including an inrush current rating of 6 amps for 10 milliseconds, ensures stable operation under transient conditions.
