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 ensures accurate temperature/process variable measurement.

5. Harsh Environment Protection: Conformal coating defends against dust, humidity, and chemicals.

Application Scenarios

• Process Industries: Chemical, petrochemical, power generation, pulp & paper (harsh areas: high humidity, dust, corrosive fumes).

• Temperature Monitoring: Thermocouple/RTD inputs for furnaces, reactors, pipelines.

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

• CE/UL‑Compliant Installations: Industrial sites requiring CE/UL certification and conformal coating.

• Non‑Redundant Control Systems: Standard‑availability processes without dual‑controller redundancy.

Key Differences: 51304437-150 vs -100

Compatibility Note
