Exceptional Measurement Precision
The MC-TAIH14 features 18-bit ADC per channel delivering ±0.03% accuracy for ultra-precise measurement. This high resolution captures fine process variations invisible to standard modules. You therefore achieve tighter control and improved product quality.
Each channel maintains accuracy across temperature with only ±25 ppm/°C drift. This stability ensures reliable performance despite ambient temperature changes in process areas.
Advanced Signal Conditioning
We equipped this module with superior >130 dB common mode rejection at 50/60 Hz. This exceptional performance eliminates virtually all interference from AC power lines. >70 dB normal mode rejection filters out series-mode noise on input signals.
2000 V RMS isolation between field wiring and logic circuitry provides enhanced protection. 500 V DC channel-to-channel isolation prevents fault propagation between different field signals.
Versatile Input Capabilities
The Honeywell MC-TAIH14 accepts a wide range of signals including 4-20 mA, 0-20 mA, 0-5 V, 1-5 V, ±10 V, and ±100 mV. The ±100 mV range accommodates thermocouples and low-level sensors directly. This versatility reduces external signal conditioning requirements.
Input impedance of >20 MΩ for voltage signals ensures negligible loading on sensitive transmitters. 250 Ω termination for current signals provides standard loop loading for 4-20 mA devices.
High-Speed Performance
The module updates all channels within 5 ms, providing fast response for critical control loops. This speed suits applications requiring rapid detection of process upsets. You therefore maintain tight control even in dynamic processes.
Robust Mechanical Design
Measuring 260 mm x 50 mm x 210 mm and weighing 1.4 kg, the MC-TAIH14 occupies a single slot in TDC 3000 racks. 0°C to +60°C operating range suits most process applications. 5% to 95% non-condensing humidity tolerance ensures reliable performance in varying conditions.
