Product Description
The Honeywell MC-TAIH12 51304337-150 actively provides high-level analog input/STI Field Termination Assembly functions for redundant process control systems. It supports 16 differential analog inputs, ensuring consistent and accurate data acquisition. The module comes in coated (MC-TAIH12) and uncoated (MU-TAIH12) versions, allowing flexible use in standard or harsh industrial environments.
Moreover, its architecture enhances reliability by providing seamless redundancy and continuous signal integrity during failover operations.
Functional Highlights
- Versatile Signal Support: Handles voltage (0–5V, 1–5V) and current (4–20 mA) inputs.
- High Accuracy: 16-bit A/D conversion with 14-bit precision utilized for stable readings.
- Strong Noise Immunity: 70 dB common-mode rejection from DC to 60 Hz.
- Fast Sampling: Input scan rate reaches 4 samples per second per channel.
- Surge Protection: Complies actively with ANSI/IEEE C37.90.1-1978 standards.
In addition, its redundant failover design ensures no missed data cycles, maintaining ±2% accuracy at 0V common mode.
