Sourced directly from authorized channels, the 1797-PS1N is a precision-engineered Flex Ex Quad-Ex DC Output Power Supply Module manufactured by Allen-Bradley (Rockwell Automation). This unit is 100% Brand New and Factory Sealed, designed to deliver stable, intrinsically safe power distribution across hazardous-area distributed I/O architectures. As a critical component within the Allen-Bradley Flex Ex I/O system, the 1797-PS1N meets the rigorous demands of Class I Division 2 and ATEX Zone 2 environments — making it an indispensable Original Spare Part for any PLC System or Control Module operating in explosive atmospheres.

Procurement teams managing Oil & Gas refineries, chemical processing facilities, and offshore platforms consistently specify the 1797-PS1N to replace aging or end-of-life power supply modules without compromising system integrity. Its Quad-Ex output topology simultaneously powers multiple intrinsically safe field devices while maintaining galvanic isolation — a capability that directly addresses the uptime and safety mandates of Safety Instrumented Systems (SIS) and DCS architectures. Every unit ships with factory calibration documentation and full compliance certificates, reinforcing its status as a 100% Original and Brand New Industrial Automation component.

Whether you are executing a planned maintenance shutdown or responding to an unplanned failure, this module integrates immediately into existing Flex Ex terminal base configurations. Contact our team today for a fast quotation and confirmed lead time.

Typical Application Scenarios

✅ Oil & Gas Upstream & Midstream: Wellhead control panels and pipeline SCADA systems demand intrinsically safe power modules rated for Zone 1/Zone 2. The 1797-PS1N’s IECEx and ATEX certifications make it the preferred Original Spare Part for these high-stakes environments.

Chemical & Petrochemical Plants: Continuous process control in the presence of flammable vapors requires robust, heavy-duty power distribution. This Control Module eliminates the risk of ignition while sustaining reliable I/O communication across the PLC System.

Power Generation Facilities: Turbine monitoring and protection systems built on Allen-Bradley Flex Ex platforms rely on precision DC power supply modules to maintain SIS loop integrity. The 1797-PS1N supports these critical applications without requiring system redesign.

✅ Pharmaceutical Manufacturing: FDA-regulated production environments with classified hazardous zones benefit from the module’s hot-swap capability, minimizing downtime during GMP-compliant maintenance windows.

✅ Offshore Marine & FPSO Platforms: Harsh marine environments demand Industrial Automation components rated for wide temperature ranges and vibration resistance. The 1797-PS1N’s -20°C to +60°C operating range and DIN-rail mounting make it ideal for offshore control cabinets.

Core Features & Technical Advantages

• Quad-Ex DC Output Architecture: Simultaneously powers up to four intrinsically safe field device circuits, maximizing I/O density in hazardous-area panels.
• 100% Original and Brand New: Factory-sealed with full Rockwell Automation traceability — no refurbished or counterfeit risk.
• ATEX / IECEx / Class I Div 2 Certified: Compliant with global hazardous-area standards for seamless international project deployment.
• Galvanic Isolation: Robust channel-to-channel isolation protects sensitive field instrumentation from ground loops and transient surges.
• Hot-Swap Design: Modules can be replaced under power without shutting down the Flex Ex backplane, supporting zero-downtime maintenance strategies.
• LED Diagnostic Indicators: Onboard status LEDs accelerate fault isolation, reducing mean time to repair (MTTR) in critical PLC System environments.
• Wide Operating Temperature: Rated -20°C to +60°C (-4°F to +140°F) for reliable performance in extreme industrial climates.
• DIN Rail Compatible: Mounts directly onto standard Flex Ex terminal bases (1797-TB3, 1797-BIC) — no additional hardware required.

Technical Specifications & Selection Guide

Selection Guide: The 1797-PS1N is the correct power supply choice when your Flex Ex I/O system requires intrinsically safe DC output for Zone 2 / Div 2 field devices. For Zone 0 / Div 1 applications, consult Rockwell Automation’s certified system integrators for alternative configurations. Pair with 1797-TB3 terminal bases and 1797-CEC bus connectors for a complete Flex Ex node assembly.

FAQ — Frequently Asked Questions

Q1: What is the price of the 1797-PS1N, and do you offer volume discounts?
A: Pricing for the 1797-PS1N varies based on order quantity, market availability, and lead time requirements. We offer competitive tiered pricing for bulk procurement — please submit an inquiry with your required quantity and project timeline for a formal quotation within 24 hours.

Q2: How quickly can the 1797-PS1N be shipped after order confirmation?
A: In-stock units ship within 1-2 business days via DHL, FedEx, or UPS Express. For urgent plant shutdowns, same-day dispatch is available upon request. Typical transit time to North America and Europe is 3-5 business days.

Q3: Can you provide a datasheet or technical documentation for the 1797-PS1N?
A: Yes. The official Allen-Bradley 1797-PS1N datasheet and installation instructions (publication 1797-UM001) are available upon request. Contact our team at sale@ninermas.com and we will provide the full technical package, including wiring diagrams and certification documents.

Q4: Is this a genuine Allen-Bradley Original Spare Part, or a third-party compatible module?
A: This is a 100% Original and Brand New Allen-Bradley 1797-PS1N sourced through authorized Industrial Automation supply channels. We do not sell counterfeit, refurbished, or third-party compatible substitutes. A Certificate of Authenticity is available upon request.

Q5: Is the 1797-PS1N compatible with the standard 1794 Flex I/O platform?
A: No. The 1797 Flex Ex series is a dedicated intrinsically safe platform and requires its own terminal bases (1797-TB3, 1797-BIC). It is not interchangeable with the standard 1794 Flex I/O system due to the intrinsic safety barrier architecture.

Q6: Can you support long-term supply agreements for MRO and spare parts programs?
A: Absolutely. We work with maintenance, repair, and operations (MRO) teams across Oil & Gas, Power, and Chemical industries to establish blanket purchase orders and consignment stock programs for critical Control Module spares including the 1797-PS1N.
