The Allen-Bradley 1797-IJ2 is a sophisticated two-frequency input module in the 1797 series, adept at managing radio frequency signals across two channels. Designed with precision, it features a thermal dissipation rate of 14.5 BTU per hour, IP20 protection, and must be installed on a terminal base unit such as the 1797-TB3 or 1797-TB3S. With an operational temperature range from -20 to 70 degrees Celsius and humidity tolerance from 5 to 95%, this unit also includes three distinct status indicators for streamlined operation, making it an essential choice for environments keen on precision and safety in signal transmission.
