Allen-Bradley 1797-PS2N Power supply unit

The 1797-PS2N is an intrinsically safe Power supply unit from Allen-Bradley’s Flex Ex series. This power supply is a 24 VDC rated device with quad-Ex output, each output providing an output voltage range of 19.2-31.2 VDC with a nominal voltage of 24 VDC. Additionally, each output delivers an output power of 0f 8.5 Watts. The 1797-PS2N is approved for installation in Class I Division 1 Group A, B, C, D; Class II Division 1 Groups E, F, G; Class III (only UL/cUL) and Class I Division 1 Groups B-D T4 (only FM) industrial location or areas. Similarly, the device’s output IS type are rated for Class I Division 1 Groups A, B, C, D; Class II Division 1 Groups E, F, G; Class III (only UL/cUL) and Class I Division 1 Groups B-D T4 (only FM) as well. The 1797-PS2N’s input voltage range is 19-32 VDC and terminated via terminals 1,2, 4, and 5. It has a current consumption of 3.1 Amperes and 5% ripple. Connections can be made via the input power entrance which is 1 in. Nipple Pipe Thread (NPT), 6 in. conduit allowed between power supply and seal (UL and C-UL) or 1 in. NPT, 0 in. conduit allowed between power supply and seal (FM).
