Main Functions

1. Provides signal conditioning, termination and galvanic isolation for LCI static‑starter and turbine‑auxiliary I/O signals between field‑mounted sensors, CT/LEM transducers and the Mark V ADMA/DSPC control hardware. Converts raw field‑measurement signals into compatible levels for DSP processing.
2. On‑board jumpers and DIP‑switches enable channel‑configuration for different signal types without modifying other system boards. 17 LED indicators offer direct visual channel‑status observation for on‑site maintenance troubleshooting.
3. Four buffered analog output channels deliver conditioned control signals to external drive‑related equipment. Integrated surge‑suppression components protect control‑system electronics from field‑side transient noise.

Installation & Wiring Requirements

1. Cut off complete rack power supply before installation or replacement. Non‑hot‑swappable. ESD wrist‑strap protection is mandatory during board handling.
2. Secure DS200DDTBG1A onto cabinet rack with four mounting screws. Reproduce jumper‑setting and DIP‑switch‑configuration exactly matching the original hardware settings. Secure field‑wiring terminals and system‑bus headers firmly.
3. All field wiring must strictly follow Mark V / LS2100 system wiring drawings. Reliable protective‑earth connection for control cabinet is mandatory.
4. After replacement: Restore rack power supply. Verify LED status indications. Inject test signals for each analog input channel and confirm controller read‑back accuracy. Validate static‑starter related control‑loop response.
5. Replacement note: Misconfigured jumpers or DIP‑switches will result in incorrect signal scaling, static‑starter malfunction or turbine‑trip events. Full‑system commissioning and protection‑logic verification test is mandatory before putting turbine‑starter control into service.
