Core Functions

1. Low-Level Signal Conditioning: Converts and isolates weak analog signals from thermocouples, RTDs, and transmitters.

2. Field Termination: Centralizes low-level analog wiring from field sensors to DCS IOPs.

3. Galvanic Isolation: Protects DCS from common-mode noise, ground loops, and high-voltage transients.

4. High-Precision Conversion: 15-bit A/D conversion ensures accurate measurement of temperature and process variables.

5. Signal Compatibility: Supports multiple sensor types (thermocouple, RTD, voltage, current) for versatile applications.

Application Scenarios

• Process Industries: Chemical, petrochemical, power generation, pulp & paper (standard areas, non-CE).

• Temperature Monitoring: Thermocouple/RTD inputs for furnace, reactor, and pipeline temperature control.

• Low-Level Signal Measurement: Millivolt-level voltage or 4–20 mA current from pressure/level/flow transmitters.

• General Industrial Environments: Non-harsh areas with normal humidity, dust, and temperature conditions.

• Non-Certified Installations: Cost-effective solutions for sites not requiring CE/UL compliance.

Key Differences: 51304437-100 vs -150

Compatibility Note

• Pin-compatible with 51304437-150; direct replacement in TDC3000/TPS UCN racks.

• Recommended for new non-redundant installations in standard, non-CE environments (cost-effective).
