Description
Triconex 9573-110F Technical Specifications:
- Input Type: Analog current (4-20mA) or voltage (0-10V).
- Channel Count: Multiple channels per board.
- Module Compatibility: Tricon analog input modules (e.g., 3700A, 3721).
- Loop Power: Supports 2-wire and 3-wire transmitter configurations.
Functional Features:
- Signal Filtering: Hardware filtering to reject high-frequency noise.
- Loop Power Supply: Provides regulated 24VDC loop power for 2-wire transmitters.
- Diagnostic Support: Open wire and short circuit detection.
- Precision Resistors: High-precision shunt resistors for accurate current-to-voltage conversion.
Application Scenarios:
- Temperature, pressure, flow, and level transmitter connections.
- Valve position feedback monitoring.
- Critical process variable measurement in SIS.
- Redundant analog signal acquisition.
Performance Parameters:
- Accuracy: High-precision signal conditioning with minimal drift.
- Input Impedance: Low impedance for current loops, high impedance for voltage.
- Noise Rejection: Excellent common-mode and differential-mode noise rejection.
Material Composition & Structural Characteristics:
- PCB: Multi-layer board with guarded traces to prevent leakage currents.
- Components: Precision 0.1% tolerance resistors and low-drift capacitors.
- Terminals: Gold-plated or tin-plated screw terminals for low contact resistance.
- Shielding: Integrated shield termination for each channel.
Working Principle: Analog field signals are connected to the 9573-110F terminals. For current signals, the board routes the signal through a precision shunt resistor to convert it to a voltage. The signal is then filtered and routed to the analog input module via the backplane. Loop power is provided from the module through the terminal board to the transmitter.
Installation Requirements:
- Shielded Cable: Use shielded twisted-pair cable for all analog signals.
- Shield Grounding: Connect shields at the terminal board only to prevent ground loops.
- Polarity: Observe correct polarity for DC signals and loop power.
- Separation: Route analog cables away from digital and power cables.
Usage Precautions:
- Ground Loops: Avoid multiple ground connections for analog shields.
- Signal Limits: Do not exceed maximum input voltage/current ratings.
- Calibration: Perform loop checks with calibrated signal sources.
- Moisture Protection: Keep terminal boards dry; moisture causes signal drift.
