GE DS3820LT4A1C1A Load Tracking Controller Panel Module
DS3820LT4A1C1A is a load tracking controller panel module for GE Mark IV (DS3800 series) gas/steam turbine control system. Installed on the Mark IV control rack, providing local human-machine operation and load tracking control functions.
DS3820LT4A1C1A Function: Complete turbine load tracking calculation, automatically adjust unit output load according to grid instructions; Local panel enables parameter viewing, setting, operation, and reset; Collect key data such as unit load and speed, and participate in closed-loop load regulation of the steam turbine; Provide fault status display and trip indication; Interacting with the Mark IV system motherboard bus, transmitting operation instructions and operational data to ensure stable operation of the unit in response to grid load demands.
Key Applications
- Process Automation: Executes sequential and regulatory control for continuous/ batch processes.
- Critical Safety Systems: Emergency Shutdown (ESD), fire & gas, and SIL 3–capable applications.
- Medium-to-Large PLC Systems: Controls up to 12K discrete I/O and 8K analog I/O (simplex mode).
- Distributed Control: Interfaces with IC660/IC661 remote I/O and Series 90‑70 local I/O.
- Data Acquisition & Communication: High‑speed data handling and integration with SCADA/host systems.
