Core Function

SPID PROFIBUS‑DP terminal board for Mark VIe turbine control system. It is used together with IS220PPRFH1B PROFIBUS‑DP master I/O pack. It provides physical signal termination and isolation conversion for field PROFIBUS‑DP slave equipment wiring. 2500VAC isolation effectively isolates field‑side interference from internal rack circuits. Built‑in ID chip enables automatic hardware identification by the control system. It supports simplex and TMR triple‑modular redundant architecture, realizing safe signal access for PROFIBUS‑DP field bus and protecting the internal control hardware from external surge interference.

Product Details

IS200SPIDG1ABA belongs to SPID series PROFIBUS signal termination hardware for GE Speedtronic Mark VIe turbine control system.

This passive terminal board undertakes physical interface conversion for PROFIBUS‑DP bus. The field PROFIBUS‑DP cable connects to DB9 port on this board, and internal signals are transmitted to IS220PPRFH1B gateway module via ribbon cable. High‑strength galvanic isolation barrier separates field bus from control backplane, restraining surge noise and ground loop interference coming from field instruments and drives. The electronic ID chip allows ToolboxST software to automatically identify hardware model without manual configuration. Conformal coated circuit board improves anti‑vibration, moisture‑proof and anti‑electromagnetic‑interference performance, adapts to harsh working conditions of power‑plant turbine cabinet. Widely deployed in gas‑steam turbine combined‑cycle unit control cabinets for auxiliary field‑bus signal access.

It belongs to critical PROFIBUS terminal spare‑part for Mark VIe turbine control system, widely used in overhaul and renovation projects of power generation units.

It is important spare hardware for PROFIBUS‑DP signal loop debugging and defective IS200SPIDG1ABA board replacement.
