Product Overview
The 1797-IJ2 is a Flex I/O (FLEX Ex) 2-point frequency input module produced by Allen-Bradley. It belongs to the 1797 FLEX Ex distributed I/O platform designed for hazardous-area use and intrinsically safe terminal bases. The module monitors two channels for frequency or gate input signals and provides local alarming. Typical industrial applications include monitoring flowmeters, shaft encoders, or other rotating-equipment sensors in hazardous environments. The 1797-IJ2 module requires a 1797-TB3/-TB3S terminal base and integrates into Flex I/O systems within broader control systems.
