Honeywell TAMR04 RTD Temperature Analog Input Multiplexer Module
Honeywell TAMR04 is a dedicated low-level analog input multiplexer module built for Honeywell TDC3000 UCN distributed control systems, widely applied in petrochemical refineries, thermal power plants, oil & gas facilities and continuous process manufacturing industries. Honeywell TAMR04 collects accurate temperature signals from RTD and thermocouple field sensors and transmits calibrated data to the main DCS controller, acting as an irreplaceable spare part for temperature monitoring and closed-loop process control. Plant automation engineers rely on Honeywell TAMR04 to deliver stable, drift-free temperature measurement under high-temperature, dusty industrial operating environments.
