Description
Foxboro P0916DG
Technical Specifications
- Processor: 32-bit industrial-grade RISC processor.
- Execution Speed: 0.1 microseconds per boolean instruction; 0.5 microseconds per floating-point instruction.
- Memory: 8 MB program memory and 4 MB data memory.
- Communication: Integrated 100 Mbps Fiber Optic Ethernet and standard Ethernet 10/100BaseTX.
- Power Supply: 24 VDC, 10 W typical power consumption.
Functional Features
- High-Speed Processing: Capable of executing thousands of control blocks per second with scan rates as fast as 50 ms.
- Redundancy Support: Designed to operate in a 1:1 hot-standby fault-tolerant configuration for maximum system availability.
- Extensive I/O Management: Supports up to 32 Series 200 Fieldbus Modules (FBMs) natively, expandable to 128 FBMs with an FEM100 expansion module.
- Advanced Diagnostics: Continuous self-monitoring and real-time alarm detection to ensure process safety.
Application Scenarios
Widely deployed in critical process industries including oil and gas, petrochemicals, power generation, and water treatment, where high availability and deterministic control are mandatory.
Performance Parameters
- Operating Temperature: 0°C to 60°C (32°F to 140°F).
- Storage Temperature: -40°C to 85°C.
- Protection Rating: IP20.
- Environmental Rating: ISA S71.04 Class G3 (Harsh environments).
Material Composition
Housed in a rugged, die-cast aluminum enclosure that provides excellent electromagnetic interference (EMI) shielding and acts as a passive heat sink. Internal PCBs are conformal-coated to protect against moisture, dust, and corrosive gases.
Structural Characteristics
Compact modular form factor (140 mm x 165 mm x 45 mm) designed for DIN rail or baseplate mounting. Features front-panel LEDs for power, run, fault, and communication status, along with integrated fiber optic and Ethernet ports.
Working Principle
The P0916DG continuously scans connected FBMs for process data, executes the user-defined control strategy in real-time, and writes control outputs back to the FBMs. In redundant configurations, the primary and secondary processors synchronize their memory states; if a hardware failure is detected, the healthy processor assumes control instantly without disrupting the process.
Installation Requirements
Must be installed in a properly grounded control cabinet. Requires standard 100 Mbps multimode fiber optic cabling for network connection. Ensure adequate ventilation and maintain ambient temperature within specified limits.
Usage Precautions
Always ensure the redundant power supply is active. When replacing a fault-tolerant pair, verify synchronization status before removing the faulty module. Avoid exposing the module to direct sunlight or extreme thermal shock.
