UT150-1 Product Specification (English Version)

1. Product Overview

2. Core Functions

1. Multi-Type Signal Acquisition: 8 independent channels, supporting Thermocouples (J/K/T/E/N/R/S/B), RTDs (Pt100/Pt500/Ni100), and mV signals (±100mV).

2. Independent Signal Processing: Each channel features independent Cold Junction Compensation (CJC) and linearization algorithms for high accuracy across the full range.

3. High-Precision Conversion: Accurately converts analog temperature signals to digital for DCS monitoring, logic judgment, and process control.

4. Hardware Redundancy: Supports redundant configuration with seamless failover (<100ms) to prevent data loss and unplanned shutdowns.

5. Fault Diagnosis: Provides wire break detection, over-range alarms, and self-diagnostics for quick troubleshooting.

6. System Communication: Communicates with the main controller via the DCS backplane bus for data upload and command reception.
