The 1797-PS2E2 module is a FLEX EX /0 series intrinsically safe IECEX 24 volt DC rated power module designed and manufactured by Allen-Bradley. 1797-PS2E2 PSU(Power supply unit is intrinsically safe
One of the most important components of the system. The goal is 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. 1797-PS2E2 module
The other task is to set the limit of available energy and adjust it to the specified safe level. All 4 output channels can be restricted independently. 1797-PS2E2 The IECEX PSU module is its 4
Each of the output channels provides 8.5 watts of power. This special unit for explosive environments outputs a rated voltage of 24 volts DC, which is the component connected to the FLEX Ex system in hazardous areas
The only power source needed. Input connectors for 24 volts DC are located at terminals 1, 2, 4 and 5. There are 4 terminals covering 2 power inputs for power input redundancy. The acceptable input voltage range is 18
To 32 volts DC.
The Allen-Bradley 1797-PS2E24-Ex Output DC power module features an IP 65/NEMA Class 7B fireproof housing with improved input and output security terminals. Input DC power supply gland is one
The M20x1 5 can accept cables with diameters from 6 to 12 mm. The power output gland (of which there are four) is M16X5 and accepts cables 4 to 8 mm wide. Through these cables, power is transmitted to the execution
Device, valve, sensor or transmitter. The 1797-PS2E2 module supports live disassembly and insertion, which enables cable connections in hazardous areas while the system is in operation.
