Allen-Bradley 1797-PS2E2 FLEX Ex Power Supply Module

Product Overview

The 1797-PS2E2 is an intrinsically safe FLEX Ex power supply module manufactured by Allen-Bradley as part of the Flex I/O 1797 series. It is engineered for hazardous and explosive industrial environments, providing reliable and isolated power for control circuits.

Designed for intrinsically safe systems, the 1797-PS2E2 delivers 24 VDC across four independent output channels, each supplying 8.5 Watts, ensuring safe energy levels in hazardous zones. The module isolates input power from the hazard area while regulating output energy, minimizing the risk of electrical faults affecting connected devices.

With dual input terminals for redundancy, the unit supports input voltages ranging from 18 to 32 VDC. Its low ripple of 5% AC and a power dissipation of 21 W ensures stable and safe operation for sensitive control systems. Weighing 12 lbs (5.44 kg), this module combines safety, reliability, and ease of installation.
