Description
Foxboro FBM202
Technical Specifications
- Model Number: FBM202 (Part Number: P0926EQ)
- Channel Capacity: 8 isolated input channels
- Signal Type: Thermocouple / Millivolt (mV)
- System Compatibility: Foxboro I/A Series
Functional Features
- Direct Thermocouple Interface: Supports multiple thermocouple types without external signal conditioning.
- Advanced Filtering: Built-in digital filtering to eliminate power line noise and electromagnetic interference.
- Fail-Safe Detection: Detects open thermocouple circuits and alerts the control system.
Application Scenarios
Crucial for temperature profiling in chemical reactors, boilers, furnaces, and heat exchangers.
Performance Parameters
- Accuracy: High-resolution measurement with minimal thermal drift.
- Isolation: Channel-to-channel and channel-to-ground galvanic isolation.
Material Composition
Precision-matched internal components to ensure consistent performance across all 8 channels in varying ambient temperatures.
Structural Characteristics
- Standard FBM Footprint: Plugs directly into standard I/A Series baseplates.
- Clear Labeling: Silkscreen identifies specific thermocouple terminals and CJC points.
Working Principle
The module measures the micro-volt signals generated by thermocouples, applies automatic cold junction compensation based on internal temperature sensors, and linearizes the data before digital transmission.
Installation Requirements
Use proper thermocouple extension wires. Ensure the termination assembly is correctly wired for the specific thermocouple type.
Usage Precautions
Never connect voltage sources to thermocouple inputs. Verify the thermocouple type matches the system configuration.
