MU‑TAMR03: Module Model

MU = Module Unit (FTA Series)

TAMR = Temperature Analog Multiplexer RTD (Temperature Analog Multiplexer - RTD Type)

03 = Hardware Version (175 corresponds to the high-density enhanced version, 125 is the standard version) Technical Specifications

Channel: 32 low-level analog input (125 has 16 channels, double density)

Signal type:

RTD: Pt100/Pt1000 (3-wire / 4-wire, supports high-precision matching)

Thermocouple: K/J/T/E/R/S/B/N type (higher cold junction compensation accuracy)

Millivolt: ±25 mV, ±50 mV, ±100 mV, ±500 mV (multi-range compatibility)

Accuracy: ±0.02% FS (25°C), drift ≤ 5 ppm/°C (better than 125's 10 ppm/°C)

Isolation: 1500 V RMS (channel-to-bus; channel-to-channel isolation enhanced)

Input impedance: RTD ≥ 2 MΩ; thermocouple / mV ≥ 20 MΩ (reduces load error)

Sampling rate: 15 Hz per channel (higher than 125's 10 Hz)

Resolution: 16 bits

Power supply: Backplane 24 VDC (±10%), power consumption ≤ 8 W

Operating temperature: -25°C ~ +75°C (broader range)

Hot-swappable: Supported

Fault detection: open circuit / short circuit / sensor break / cold junction fault (more comprehensive diagnosis)

Common mode suppression: ≥ 110 dB (50/60 Hz, stronger anti-interference)

Interface and status

System side: High-density UCN flat cable, compatible with C200/C300/TPS controller I/O

Field side: 32 detachable gold-plated terminals (anti-oxidation, low contact resistance)

Indicators: module OK/FAULT, power, 32 channel status lights

Configuration: DCS software configures signal type, range, filtering, cold junction compensation

Core function

32-channel high-density acquisition: single module 32 channels, double capacity of 125, saves I/O slots and costs

Ultra-high precision and low drift: ±0.02% FS, 5 ppm/°C, suitable for precise temperature / small voltage measurement

Full type sensor compatibility: covers mainstream RTD, thermocouple and mV signals, suitable for multiple scenarios

Strong isolation and high anti-interference: 1500 V RMS isolation, 110 dB common mode suppression, suppresses industrial noise

Wide temperature range and high stability: -25°C ~ +75°C, suitable for harsh conditions

Hot-swappable and comprehensive diagnosis: maintenance without downtime, real-time detection of sensor and circuit faults Applicable scenarios

Industry: Oil and gas, petrochemicals, power generation (boilers / steam turbines), metallurgy, heat treatment, chemical industry, pharmaceuticals

Applications: High-density temperature measurement points, high-precision RTD / thermocouple measurement, weak voltage signal acquisition, low-level circuits in harsh environments

Compatibility: Experion PKS (C200/C300), TDC 3000, TPS
