Description
- The WOODWARD 5462-757 is a specialized analog input module designed for the MicroNet control platform, specifically tailored for Resistance Temperature Detector (RTD) monitoring. This module allows the control system to accurately measure temperatures from various points on turbines, engines, or compressors using industry-standard RTD sensors. Known for its high precision and low drift, the 5462-757 ensures that thermal parameters are integrated into the control logic with high reliability, supporting critical functions like exhaust gas temperature (EGT) monitoring and bearing temperature protection.
Technical Specifications (Datasheet)
Model Number: 5462-757 Manufacturer: Woodward Module Function: RTD Input (Resistance Temperature Detector) Input Channels: 8 Channels RTD Type Support: Pt100, Pt200, Pt500 (Configurable) Measurement Resolution: 0.1°C A/D Resolution: 16-Bit Dimensions: 19.8 cm x 14.5 cm x 2.5 cm Weight: 0.70 kg Country of Origin: USA
Application Fields
The 5462-757 module is primarily utilized in sectors where thermal management is vital for mechanical safety:
- Gas Turbine Monitoring: Measuring exhaust gas temperatures to ensure combustion efficiency and prevent blade damage.
- Bearing Protection: Monitoring oil and bearing temperatures in large rotating machinery to prevent catastrophic mechanical failure.
- Winding Temperature: Tracking the internal heat of generator or motor windings in power plants.
- Heat Exchanger Control: Providing feedback for cooling systems in chemical and petrochemical processing plants.
Product Usage Instructions
- Installation: Power down the MicroNet rack and insert the module into the designated I/O slot. Ensure the module is fully seated against the backplane connector before tightening the retention screws.
- Sensor Wiring: Connect your RTD sensors to the field terminal block. It is highly recommended to use 3-wire or 4-wire RTD configurations to compensate for lead-wire resistance and maintain accuracy.
- Shielding: Use shielded, twisted-pair cabling for all RTD inputs. Connect the shields to the designated ground bus to minimize signal noise from high-voltage equipment.
- Software Configuration: In the Woodward GAP (Graphical Application Programmer) environment, configure each channel for the specific RTD type and temperature range required for your application.
- Diagnostic Check: After powering up, verify the “Status” LED. A green light indicates normal operation. Use the service tool to check the live temperature readings against a known reference to confirm calibration.
Frequently Asked Questions (Q&A)
Q: Does the 5462-757 support 2-wire RTD connections? A: While possible, 2-wire connections are not recommended due to the potential for lead-wire resistance causing temperature offsets. 3-wire or 4-wire setups provide significantly better accuracy.
Q: Can this module detect a broken sensor wire? A: Yes, the module includes open-circuit detection logic. If a sensor wire is broken or disconnected, the module will report a fault signal to the CPU, allowing the system to initiate a safe shutdown or alarm.
Q: Is the module compatible with MicroNet TMR systems? A: Yes, the 5462-757 is designed to work in both Simplex and Triple Modular Redundant (TMR) MicroNet architectures for high-availability applications.
Q: Where can I get technical support or a replacement unit? A: You can find comprehensive documentation and inventory for the WOODWARD 5462-757 by visiting https://www.newplcdcs.com for all your industrial automation requirements.
