PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1797-PS2E2 is an intrinsically safe power supply module for the FLEX I/O architecture. This unit isolates incoming electrical circuits from hazardous area control networks. It prevents electrical fault propagation from the input side to the output terminals. The unit provides four intrinsically safe limited output channels. Each channel delivers up to 8.5 Watts of DC power. The module requires an input voltage ranging from 18 to 32 Volts DC.
The power supply is enclosed in an IP65 and NEMA 7B flame-proof housing. Input connections include four terminals for dual redundant power inputs. One M20x1.5 cable gland secures incoming power cables between 6 and 12 millimeters in diameter. Four M16x1.5 output glands accommodate field cables measuring 4 to 8 millimeters across. The unit supports module removal and insertion under power during active operations in classified locations.
