Description
The Honeywell MC-TAMR04 (Order Code: 51305907-175) is a UCN (Universal Control Network) Low Level Analog Input Multiplexer designed for high-precision data acquisition in industrial process control environments. This field termination assembly (FTA) is engineered to interface directly with thermocouple signals, providing reliable signal conditioning and multiplexing for DCS integration. As a legacy component, this unit is essential for maintaining and extending the operational life of established Honeywell control systems.
Features
- Designed for low-level analog input applications, specifically optimized for thermocouple signal processing.
- High-resolution 24-bit ADC architecture for precise process monitoring.
- Robust common-mode rejection exceeding 140 dB at 50/60 Hz to ensure signal integrity in electrically noisy industrial environments.
- High input impedance (>10 MΩ) to minimize loading effects on sensitive sensors.
- Standardized FTA design for simplified integration into existing Honeywell DCS infrastructure.
