Application Scenarios
Widely deployed in oil and gas, refining, petrochemical, and power generation industries for high-precision data acquisition in PLC, DCS, and SCADA systems.

Performance Parameters

  • Operating Temperature: -40°C to +70°C
  • Storage Temperature: -55°C to +85°C
  • Response Time: Less than 10ms
  • Humidity Tolerance: 0 to 95% RH (non-condensing)

Material Composition
The module is constructed with a robust, single-wide industrial form factor. The internal electronics are conformal-coated to resist corrosion, moisture, and harsh environmental conditions.

Structural Characteristics
Compact DIN rail mountable design weighing approximately 0.4 kg. It mounts directly onto 200 Series baseplates and utilizes designated Terminal Assemblies (TAs) for field wiring.

Operating Principle
The module receives 0-20 mA differential signals from field transmitters via the terminal assembly. It conditions, isolates, and digitizes these analog signals before transmitting the data over the redundant 2 Mbps Module Fieldbus to the associated FCM or FCP controller.

Installation Requirements
Must be mounted on a compatible Foxboro 200 Series baseplate in a clean, ventilated enclosure. Adequate front access is required to facilitate hot-swapping, and a low-impedance protective earth must be maintained.

Usage Precautions
Always observe standard ESD (Electrostatic Discharge) precautions when handling. Ensure that field wiring strictly adheres to the designated Terminal Assembly (TA) specifications and that the 24 VDC backplane power supply is stable and within tolerance.
