Application Fields
The IS200SCLTH1ABB is a primary termination point for turbine and generator monitoring:
- Temperature Monitoring: Terminating RTD and thermocouple signals from bearing housings and exhaust ducts.
- Process Feedback: Interfacing 4-20mA signals from pressure, level, and flow transmitters.
- Generator Protection: Managing analog inputs for excitation control and stator winding protection.
- Balance of Plant (BOP): Centralizing analog signal wiring for auxiliary power plant equipment.
Product Instructions
- Safety: Ensure the system is powered down or the specific I/O pack is offline before disconnecting field wiring.
- ESD Measures: Use an anti-static wrist strap; handle the board by the plastic edges or terminal blocks only.
- Wiring: Strip field wires to the recommended length and secure them in the screw terminals. Ensure no stray strands touch adjacent channels.
- Cabling: Connect the 37-pin or ribbon cables from the I/O processor (such as the YVIB or YAIC) to the headers on the SCLT board.
- Shielding: Properly ground the cable shields at the terminal board’s grounding bar to minimize electromagnetic interference (EMI) on low-voltage analog signals.
Q&A
Q1: What is the significance of the “ABB” suffix in the part number? A1: This represents the specific hardware revision and assembly group. Revision ABB typically includes minor component updates or manufacturing improvements over the “AAA” version while remaining functionally interchangeable.
Q2: Can I use this board for both Mark VI and Mark VIe systems? A2: Yes, the SCLT board is a “core” analog terminal board used across the Speedtronic Mark series, though the specific I/O packs (Mark VIe) or VME boards (Mark VI) it connects to will vary.
Q3: How do I troubleshoot a “Signal Loss” fault on this board? A3: First, check the physical terminal tightness. Use a multimeter to verify the 4-20mA loop current or voltage at the SCLT terminals to determine if the fault is in the field device or the terminal board itself.
