Allen-Bradley 1771-IXE PLC-5 Thermocouple/Millivolt Input Module

Description

The Allen-Bradley 1771-IXE PLC-5 Thermocouple/Millivolt Input Module is an analog input module designed to collect thermocouple and millivolt signals, converting them into digital signals recognizable by PLC-5 systems for further processing and control. It features 8 independent input channels, supporting E, J, K, R, S, T type thermocouples and +/- 100mV millivolt signals, making it suitable for industrial automation scenarios such as temperature and pressure analog signal collection. Key technical specifications include a backplane current load of 750mA at 5V, a total channel update time of 50 milliseconds for all 8 channels, power consumption of 4.25 watts, and heat dissipation of 14.5 BTU per hour. The module integrates practical features: it connects to the 1771-WI field wiring arm, allowing module replacement without disconnecting wires; front-panel green RUN and red FLT indicators display power and fault status; it performs self-diagnostics during power-up and reports status, with open-circuit detection for thermocouple faults. As a single-slot module, it installs directly into 1771 chassis slots, is compatible with any PLC-5 chassis, and can be configured for readings in degrees Celsius or Fahrenheit, with cold junction compensation included for accurate thermocouple signal processing.
