Core Functions

1. High-Level Signal Acquisition: Collect 16-channel voltage/current signals from transmitters.

2. Signal Conditioning: Amplify, filter, and isolate signals to suppress EMI.

3. Data Conversion: Convert analog signals to digital for DCS processing.

4. Diagnostics: Real-time channel monitoring, fault detection, and alarm reporting.

5. System Expansion: Increase DCS analog input capacity for complex processes.

Application Scenarios

• Industries: Oil/gas, chemical, petrochemical, power, pharmaceutical.

• Uses: Connect pressure, temperature, flow, level transmitters in TDC 3000/TPS cabinets.

• Environments: Standard control rooms and field cabinets; system upgrades/replacements.

Usage & Maintenance

Usage

1. Insert into dedicated LCN slot and secure screws.
