Intrinsically Safe Outputs 4 Isolated Power Channels Flame-proof Enclosure Hazardous Area Rated Wide Input Voltage Range High Safety Standards

Product description

The Allen-Bradley 1797-PS2E2 is a FLEX Ex power supply module designed for intrinsically safe operation in hazardous environments. It accepts a 24V DC input within an 18-32V DC range and provides four isolated 8.5W outputs, totaling 34W of intrinsically safe power. This module is crucial for powering devices in potentially explosive atmospheres.

Constructed with a flame-proof enclosure rated IP 65/NEMA 7B, it ensures safety and durability. Input power connects via an M20x1.5 gland, and the four power output glands are M16x1.5. This power supply is engineered to meet stringent safety standards for use in industries like oil and gas, chemical processing, and mining.

Frequently asked questions

What is the purpose of the intrinsically safe outputs on the 1797-PS2E2?

The intrinsically safe (IS) outputs on the 1797-PS2E2 are designed to limit the electrical energy supplied to connected devices, preventing the ignition of flammable gases or dust in hazardous environments. This ensures safe operation in potentially explosive atmospheres.
