- Bus Interface: Redundant 2 Mbps Module Fieldbus.
- Power Supply: 24 VDC backplane power.
- Form Factor: Single-width 200 Series FBM.
Functional Features
- Seamless Integration: Directly mounts on 200 Series baseplates for native compatibility with I/A Series controllers.
- Hot-Swappable Maintenance: Supports online replacement without disturbing field wiring or adjacent modules.
- Redundancy Ready: Architecture supports redundant I/A nodes for maximum system availability.
- Integrated Diagnostics: Built-in status LEDs and health reporting simplify troubleshooting.
Application Scenarios
Widely deployed in upstream oil and gas wellheads, gas compression stations, refinery unit balancing, and utility systems.
Performance Parameters
- Operating Temperature: 0°C to 60°C.
- Environmental Protection: Conformal-coated electronics to adapt to industrial dust and humid environments.
Material Composition
Compact single-width enclosure with industrial-grade conformal coating on internal PCBs to enhance corrosion and interference resistance.
Structural Characteristics
- Dimensions: Standard 200 Series FBM size.
- Termination Method: Flexible field wiring via designated Foxboro Termination Assemblies (TA).
Working Principle
Acquires signals from the field TA, digitizes them, and uploads data via the backplane fieldbus protocol to the controller while receiving downstream commands to drive field actuators.
Installation Requirements
- Must be installed in a clean, well-ventilated control cabinet.
- Ensure backplane connectors are fully aligned and locked.
- Field signal wires must be connected to the matching Termination Assembly.
Precautions for Use
- Always verify the PO916PH P0916AL hardware code before replacement to prevent firmware mismatches.
- Maintain low-impedance protective grounding to enhance noise immunity.
- Observe strict ESD precautions during maintenance.
