The Honeywell MC-TAMR03 (51309218-175) is a high-performance Low Level Analog Multiplexer (Mux) module engineered for precision signal acquisition in industrial control environments. This module is designed to interface with a variety of low-level field sensors, providing reliable data conversion for thermocouple, RTD, and linear millivolt inputs within the Honeywell control architecture.
Features
Supports 32 galvanically isolated input channels for enhanced noise immunity and signal integrity.
High-resolution 14-bit data conversion ensures accurate readings across all supported sensor types.
Configurable line frequency synchronization for either 50 Hz or 60 Hz operation to minimize signal interference.
Robust input protection with a maximum normal mode continuous input rating of -1 V to 10 V.
Efficient scan rate of 32 samples per second, ensuring each channel is sampled once per second.
Applications
This module is typically deployed in process automation systems requiring the monitoring of temperature and low-voltage signals. It is ideal for integration into Honeywell Experion PKS or similar distributed control system (DCS) racks where high-density, isolated analog input processing is required for thermal management and process monitoring.
