Application Fields
The IS200VRTDH1DAC is a high-performance communication and sensing module used in heavy industrial turbine control. Major applications include:
- Gas and Steam Turbine Monitoring: Measuring bearing temperatures and exhaust gases.
- Power Generation Plants: Integrating thermal data into the Mark VI control loop.
- Oil and Gas Facilities: Temperature monitoring for large-scale compressor stations.
- VMEbus Systems: Data acquisition and transmission within the Speedtronic rack architecture.
Product Instructions
- Installation: Power down the VME rack. Align the IS200VRTDH1DAC with the card guides and slide the board firmly into the backplane connectors. Use the front-panel ejector handles to secure the seat.
- Wiring: Connect the RTD field wiring to the corresponding terminal board (typically a TBTCH1 or similar). Ensure shielded cables are used to prevent signal noise from affecting temperature accuracy.
- Configuration: The board revision “DAC” must match the configuration settings in the Toolbox software. Verify that the hardware ID is correctly recognized by the controller during the boot sequence.
- Maintenance: Periodically check the diagnostic LEDs on the front faceplate. A “FAIL” LED indicates a hardware malfunction or a communication timeout on the VMEbus.
Product Q&A
Q: What is the primary function of the IS200VRTDH1DAC? A: It serves a dual purpose: it processes RTD (Resistance Temperature Detector) signals from the field and communicates that data to the main controller via the VMEbus.
Q: Which RTD types are supported by this board? A: It is designed to support standard industrial RTDs, including 100-ohm platinum, 10-ohm copper, and 120-ohm nickel sensors, depending on the software configuration.
Q: Does this board require a separate terminal board? A: Yes, the VRTD board in the VME rack typically connects to a passive terminal board located in the cabinet where the actual field wiring is landed.
Q: Can I swap an H1DAC with an earlier H1A version? A: While they share the same base architecture, the “DAC” suffix indicates specific functional enhancements or component updates. It is critical to verify software compatibility before downgrading or upgrading revisions.
