Product Overview

The Allen-Bradley 1797-PS2E2 is a specialized Intrinsically Safe (IS) Power Supply from the FLEX Ex™ family. Designed specifically for mounting in Zone 1 or Zone 2 hazardous areas, it provides isolated 24V DC power to the FLEX Ex I/O modules and backplane. Its rugged design ensures that electrical energy is maintained at a level insufficient to ignite explosive atmospheres, even under fault conditions.

At Xiongba Automation, we understand that Hazardous Area Compliance is non-negotiable. Sourcing a 1797-PS2E2 requires more than just finding a part; it requires verifying that the hardware maintains its original safety integrity. We provide Verified Hardware for global traders who demand the highest standards for their oil, gas, and chemical industry clients.

Technical Specifications:

• Input Voltage: 18-32V DC.

• Output: Intrinsically safe power for the FLEX Ex backplane and modules.

• Hazardous Location Rating: Class I, II, III; Division 1 & 2; Zones 1 & 2 (ATEX/IECEx certified).

• Isolation: Full galvanic isolation between input and output.

• Redundancy: Supports dual-power configurations for increased system reliability.

Verification & Risk Control

Safety in hazardous zones depends on hardware perfection. Xiongba Automation enforces a 5-step audit for the 1797-PS2E2:

1. Housing & Seal Integrity: We inspect the casing for any cracks or compromises in the potting material. In an "Ex" environment, the physical seal is a critical safety barrier.

2. Certification Label Clarity: We provide high-resolution photos of the ATEX/IECEx and UL tags. These markings must be perfectly legible for site safety inspectors to approve the installation.

3. Terminal Block Check: We verify the specialized terminals are free from corrosion or "pitting," ensuring a low-resistance, spark-free connection.

4. 12-Month Hardware Warranty: 1-year B2B warranty is standard. Note: This covers the hardware's functional health. It does not cover damage caused by installing the unit in a non-compliant enclosure or exceeding the IS parameters.

5. Strict Neutral Packaging: We use certified anti-static and shock-resistant materials to ensure the 1797-PS2E2 arrives in factory-spec condition.

Project Lifecycle Support 

1. Tendering Stage (Bidding): Quoting for an offshore platform or refinery maintenance? We provide formal quotes and can help you verify the specific Ex certification revisions to ensure your bid is compliant.

2. Procurement Stage (Real Order):

   • The Redundancy Strategy: Since these are often used in pairs for redundancy, please let us know if you require a Matched Pair.

   • Live Video Verification: We offer a live power-on test to show the status LEDs, giving you 100% confidence before shipping to a remote site.

FAQ

Q: Can I use a standard 1794 power supply to replace the 1797-PS2E2? A: ABSOLUTELY NOT. The 1797 series is intrinsically safe for hazardous zones. Using a standard 1794 module in a Zone 1 area could lead to an explosion. Always replace with the exact 1797-PS2E2 part number.

Q: Does it include the mounting base? A: We supply the 1797-PS2E2 module hardware. The terminal base (e.g., 1797-TBP) is usually sold separately. Please let us know if you need the base as well.

Q: Why is this power supply so much more expensive than others? A: You are paying for the Ex Certification and the specialized internal safety components (galvanic isolators, current limiters) that prevent sparks in explosive environments. This is a life-safety product.
