Description
Foxboro P0916DV
Technical Specifications
- Signal Type: Analog Input/Output (4-20mA, 0-10V).
- Resolution: High-resolution A/D and D/A conversion.
- Channel Isolation: Channel-to-channel and channel-to-ground isolation.
Functional Features
- High Precision: Factory-calibrated for accurate measurement and control without field adjustment.
- Diagnostic Capabilities: Detects open circuits, short circuits, and out-of-range conditions.
- Filtering: Configurable digital filtering to smooth noisy field signals.
Application Scenarios
Ideal for monitoring and controlling temperature, pressure, level, and flow in refineries, chemical reactors, and utility systems.
Performance Parameters
- Accuracy: ±0.05% or better of span.
- Update Rate: Fast scan rates to capture rapid process changes.
Material Composition
Industrial-grade PCB with protective conformal coating and precision thin-film resistors for long-term stability.
Structural Characteristics
- Terminal Interface: Connects to specific Foxboro Terminal Assemblies for easy field wiring.
- Status LEDs: Visual indication of channel activity and module health.
Working Principle
The module continuously samples analog field signals, converts them to digital engineering values, and updates the control database. For outputs, it converts digital setpoints from the controller into precise analog currents or voltages to drive final control elements.
Installation Requirements
- Use shielded twisted-pair cables for all analog field connections.
- Ground the shield at the cabinet end only to prevent ground loops.
- Ensure the Terminal Assembly matches the module’s pinout.
Usage Precautions
- Never apply voltage to current input terminals.
- Verify loop power supply compatibility before energizing.
- Perform calibration verification during scheduled maintenance.
