Allen-Bradley 1797-PS1E

Overview

The Allen-Bradley 1797-PS1E is a robust and reliable FLEX Ex power supply, meticulously engineered to deliver safe and stable power within demanding hazardous-area automation systems. This AC-powered unit is a cornerstone for ensuring operational integrity in environments classified as Zone 1 or Zone 2, where the presence of flammable gases, vapours, or dust necessitates intrinsically safe solutions. Designed with a versatile 85–250V AC input range, the 1797-PS1E efficiently converts and distributes power through its four isolated, intrinsically safe (IS) outputs. These outputs are specifically configured to power IS field devices, seamlessly integrating with FLEX Ex I/O modules to create a comprehensive safety barrier. The Euro-style terminal block further enhances its applicability, making it the ideal choice for installations requiring compliance with European safety standards and wiring practices.

This critical component provides the essential link between conventional power sources and intrinsically safe instrumentation, minimizing the risk of ignition in potentially explosive atmospheres. Its integration into the modular FLEX Ex platform underscores a commitment to flexibility, scalability, and uncompromising safety in industrial applications across various sectors.
