Technical Specifications & Selection Guide

Selection Tip: Verify your TDC 3000 I/O rack slot assignment and IOTA cable type before ordering. The MC-TAIH12 designation confirms 12-channel high-density analog input capability — ideal for multi-loop temperature, pressure, and flow measurement consolidation.

Core Features & Technical Advantages

• Precision Signal Acquisition: ±0.1% of span accuracy across all 12 channels delivers the measurement fidelity demanded by advanced process control loops.
• Robust Electrical Isolation: 250 V channel-to-channel isolation eliminates ground loop interference — critical in heavy-duty industrial environments with high electromagnetic noise.
• High-Density I/O Architecture: 12 analog inputs in a single FTA footprint maximizes cabinet real estate and reduces wiring complexity for large-scale DCS installations.
• Universal Transmitter Compatibility: Accepts industry-standard 4-20 mA and 1-5 VDC signals, enabling direct connection to virtually any field transmitter without signal conditioning.
• Hot-Swap Capable: Designed for live replacement within the TDC 3000 Control Module framework — minimize process disruption during maintenance windows.
• EOL Legacy System Support: Fully compatible with end-of-life TDC 3000 infrastructure, making this Original New spare part the preferred choice for sustaining aging plant assets.
