FAQ
1. What is the main function of the Allen Bradley 1797-PS2N2?
The Allen Bradley 1797-PS2N2 is a FLEX Ex power supply designed for intrinsically safe industrial automation systems installed in hazardous areas. It accepts a 24V DC input and provides four intrinsically safe DC output channels. The power supply isolates incoming power from the intrinsically safe output circuits and limits the available electrical energy to levels suitable for FLEX Ex field devices, I/O modules, valves, actuators, and transmitters.
2. What input voltage does the 1797-PS2N2 require?
The 1797-PS2N2 is designed for a nominal 24V DC supply and operates over an input voltage range of 19 to 32V DC. The input is connected through the designated input terminals. When installing the unit, the supply voltage should remain within the specified range to maintain correct output regulation and intrinsically safe operation.
3. How many output channels does the 1797-PS2N2 provide?
The power supply provides four intrinsically safe DC output channels, with each channel rated at up to 8.5 W. The outputs are provided through terminals 10 through 17. The channels are designed to supply power to compatible FLEX Ex field equipment while maintaining the required intrinsic-safety energy limitations.
4. What are the intrinsic safety output parameters of the 1797-PS2N2?
The output voltage parameter UO is less than 9.5 V, while the output current IO is less than 1 A. For IIC applications, the specified external capacitance Co is less than 500 nF and inductance Lo is less than 8 μH. The maximum output cable resistance is less than 0.1 Ω in both directions. These parameters are important when selecting field devices, cables, and associated equipment because the complete circuit must remain within the applicable intrinsic-safety entity parameters.
5. Can the 1797-PS2N2 be used in hazardous-area applications?
Yes. The 1797-PS2N2 is specifically designed for FLEX Ex intrinsically safe applications in hazardous locations. Its certifications and classifications cover environments including Class I Division 1 and Class II Division 1 applications, with additional FM classifications for specified hazardous-area installations. Installation must follow the applicable certification, wiring, grounding, sealing, and entity-parameter requirements for the particular hazardous location.
6. What temperature range is supported by the 1797-PS2N2?
The specified operating temperature range is -20 to 70 °C (-4 to 158 °F). The power supply also dissipates approximately 21 W during operation, so enclosure conditions and surrounding equipment should be considered when designing the installation. Adequate thermal conditions are particularly important in hazardous-area installations where the ambient temperature and enclosure arrangement can affect overall system performance.
7. Can the 1797-PS2N2 be repaired in the field?
The 1797-PS2N2 is not intended to be field-repaired. Because it is part of an intrinsically safe system and its enclosure and internal circuits are associated with hazardous-area certification, opening or modifying the unit can affect its safety certification. If the power supply develops an internal fault, it should be handled according to the applicable Rockwell Automation service or replacement procedure rather than being disassembled or repaired at the installation site.
8. What should be checked when a FLEX Ex system powered by the 1797-PS2N2 does not operate correctly?
Start by checking that the DC input remains within the 19 to 32V DC operating range and that the input wiring is correctly connected. Next, inspect the four output circuits, terminal connections, field-device wiring, and the load connected to each channel. Excessive cable resistance, an incorrect field device, wiring faults, or an output load outside the permitted intrinsic-safety parameters can prevent normal operation. In a hazardous area, troubleshooting should also follow the required intrinsic-safety procedures, and the enclosure should not be opened while energized.
