The 1797-PS2E2 module is a FLEX EX I/O series intrinsically safe IECEX 24 volt DC rated power module designed and manufactured by Allen-Bradley. The 1797-PS2E2 PSU (Power supply unit) is one of the most important components of an intrinsically safe system. The purpose is to isolate the input power circuit from the hazardous area of the electrical = control circuit involved and to disable the conversion of the circuit problem from the input side to the output side. Another task of the 1797-PS2E2 module is to set the limit of available energy and adjust it to a defined safe level. All four output channels can be independently restricted by IS.
The 1797-PS2E2 Safety IECEX PSU module provides 8.5 watts of power for each of its four output channels. This special device for explosive environments offers a voltage rating of 24 volts DC, which is the only power supply needed to connect components to the FLEX Ex system in hazardous areas. Input connectors for 24 volts DC are located at terminals 1, 2, 4 and 5. There are 4 terminals covering 2 power inputs for source input redundancy. The acceptable input voltage range is 18 to 32 volts DC.
The FLEX Ex Power supply is an intrinsically safe power module designed and manufactured by Allen-Bradley to isolate the input power circuit from the hazardous area of the associated electrical control circuit and to prohibit the transfer of circuit problems from the input side to the output side.
Features of the FLEX Ex power supply include:
Intrinsically safe: The FLEX Ex power supply is intrinsically safe, meets international explosion-proof standards and can be used safely in hazardous areas.
Multiple outputs: FLEX Ex power supplies have a variety of output types, including single-phase and three-phase power supplies, AC and DC power supplies, to meet the needs of different devices and systems.
