The Allen-Bradley 1771-IXEK is a conformal-coated Analog Input Module, specifically designed for the PLC 5 platform, offering robust protection against humidity and contaminants. This module supports 8 floating differential inputs for thermocouples or millivolt input ranges, including types E, J, K, T, R, and S, as well as ±100 millivolts, with cold junction compensation and an impressive accuracy of ±0.5°C. It requires a single slot installation in a 1771 I/O chassis, with no external power supply needed, and features automatic offset and gain calibration on each channel, alongside selectable high and low-temperature alarms, ensuring precise and reliable performance.
