Allen-Bradley 1797-IJ2 two-frequency input module

The 1797-IJ2 is a two-frequency input module manufactured and designed by Allen-Bradley. This module belongs to the 1797 series of analog modules. The Allen-Bradley 1797-IJ2 two-frequency input module that works mainly transmitting and receiving radio signals between two devices. It has two frequency channels and two gate channels. The Allen-Bradley 1797-IJ2 two-frequency input module has a thermal dissipation of 14.5 BTU per hour and an approximate shipping weight of 200 grams. The Allen-Bradley 1797-IJ2 two-frequency input module features a protection rating of IP20. Even though the device cover covers the most important parts and prevents dust from entering the unit, users need to take into account that this module cannot be exposed and used without a cover.

It is recommended to provide extra protection, such as a metal enclosure. The recommended conditions for the Allen-Bradley 1797-IJ2 two-frequency input module are an operational temperature of -20 to 70 degrees Celsius and a relative humidity range of 5 to 95%. When installing the Allen-Bradley 1797-IJ2 two-frequency input module, this should be mounted on a terminal base unit (1797-TB3 or 1797-TB3S) and all the cables used during installation must be shielded. Other important factors to consider are that the Allen-Bradley 1797-IJ2 two-frequency input module is highly affected by electrostatic discharge, it is recommended to install it in a static-free workplace and to place a sign near the module to warn about electrostatic charging/discharging. The Allen-Bradley 1797-IJ2 two-frequency input module has three status indicators, A, B, and C. A is used for individual channels, B for writing individual I/O designations, and C is used as a power indicator.
