Description
Foxboro FBM06 P0400YG
Technical Specifications
- Module Model: FBM06 (P0400YG)
- Channel Configuration: 4 Pulse Input / 4 Analog Output (0-20mA)
- Signal Type: Pulse/Frequency and 0-20mA current loops
- Bus Interface: 2 Mbps Redundant HDLC Fieldbus
Functional Features
- Combined I/O Functionality: Single module provides both pulse input and analog output, saving cabinet space.
- High-Precision Conversion: Built-in high-resolution pulse counter and D/A converter.
- Complete Electrical Isolation: Full isolation between channels and system bus.
- Smart Diagnostics: Wire break detection and short circuit protection.
Application Scenarios
Used for flow meter pulse counting, turbine speed monitoring, and simultaneous analog control output.
Performance Parameters
- Output Load: Drives up to 600Ω loop impedance.
- Signal Accuracy: ±0.1% of full scale typical.
- Response Time: Software-configurable digital filtering, <10ms fastest.
Material Composition
Industrial-grade flame-retardant housing with conformal-coated PCBs. High-quality screw or crimp terminals.
Structural Characteristics
Standard FBM form factor with clear channel identification and status LEDs. High-density backplane connector supports hot-swapping.
Working Principle
Input side counts pulse/frequency signals via optocoupler isolation. Output side receives digital commands, converts via D/A and V/I circuits to drive field actuators.
Installation Requirements
Use shielded twisted pair for both PI and AO signals. Shields grounded at cabinet side only.
Precautions for Use
Verify signal types and terminal definitions. Never short-circuit output loops. Place node in “Maintenance Mode” before replacement.
