FAQ
FAQ
Q1: What is the Allen-Bradley 1797-PS2N2 used for?
A: The 1797-PS2N2 supplies intrinsically safe power to FLEX Ex I/O systems used in hazardous locations. It isolates incoming DC power and limits output energy to meet intrinsic safety requirements.
Q2: What input voltage does the 1797-PS2N2 require?
A: The power supply operates from a 19–32 VDC input source and consumes approximately 3.1 A with a maximum input power of 55 W.
Q3: What output does the 1797-PS2N2 provide?
A: It provides four intrinsically safe 9.5 VDC outputs, each rated at 8.5 W, allowing FLEX Ex modules to power field devices without additional intrinsic safety barriers.
Q4: Where is the 1797-PS2N2 typically installed?
A: It is commonly installed in hazardous industrial environments such as oil and gas facilities, refineries, chemical plants, and other process automation applications requiring intrinsically safe I/O systems.
Q5: Does the 1797-PS2N2 include intrinsic safety protection?
A: Yes. The unit features built-in galvanic isolation and limits available energy to intrinsically safe levels, eliminating the need for separate intrinsic safety barriers in many FLEX Ex applications.
Q6: What are the dimensions and weight of the 1797-PS2N2?
A: The approximate dimensions are 200 × 200 × 140 mm, and the unit weighs approximately 7.3 kg. Actual dimensions may vary slightly depending on the enclosure configuration.
Q7: Is the 1797-PS2N2 still available?
A: No. Rockwell Automation has discontinued the 1797-PS2N2. Existing systems can still be supported through repair services or replacement inventory from qualified industrial automation suppliers.
Q8: What should be checked before installing the 1797-PS2N2?
A: Verify the 19–32 VDC input power, hazardous-area certification requirements, wiring method, grounding, conduit installation, and compatibility with the connected FLEX Ex I/O modules. Follow all applicable intrinsic safety and hazardous-location installation procedures.
