Product Description

The GE IS200DTAOH1ABA and IS210DTAOH1AA are a matched high-stability dual analog output terminal board combination developed exclusively for GE Speedtronic Mark VI turbine control systems. As core analog signal output and field drive matching units for gas and steam turbine control platforms, they undertake control signal conversion, analog output driving, field actuator matching and turbine auxiliary parameter regulation tasks. The dual-board cooperative structure realizes stable and precise analog signal output for turbine closed-loop control, providing accurate execution guarantee for power generation unit operation adjustment, equipment linkage control and safety steady-state maintenance.

Adopting turbine-grade dedicated analog output circuit and high-reliability signal amplification architecture, this board set features low-distortion signal output, strong load driving capability and excellent long-term operational stability. IS200DTAOH1ABA serves as the main high-precision analog output processing board for signal conversion and logic scheduling, while IS210DTAOH1AA acts as the matching terminal output board to complete field signal driving and transmission. Built-in multi-stage surge suppression, circuit isolation and signal buffering mechanisms effectively resist strong electromagnetic interference and signal fluctuation in complex power plant environments. Equipped with real-time output status monitoring and fault self-diagnosis functions, it supports timely anomaly alarm and rapid maintenance troubleshooting. With ultra-wide temperature adaptability, vibration resistance and power industry certified rugged design, it supports 24/7 uninterrupted long-cycle stable operation for GE Mark VI turbine control systems.
