IS410STAIS2A IS400STAIS2AED

Product Overview

IS410STAIS2A and IS400STAIS2AED are STAI simplex analog input terminal boards for GE Mark VIe and Mark VIeS Speedtronic turbine control systems. IS410STAIS2A is the standard production model, while IS400STAIS2AED is an engineering variant designed for special project requirements. Both boards share the same core analog signal acquisition function.

This terminal board works in conjunction with the YAIA analog input I/O pack. It acts as the field wiring interface to receive 4-20mA analog signals from transmitters, pressure sensors, flow meters and other process instruments. The board converts analog field signals and transmits data to the Mark VIe controller for continuous process monitoring and closed-loop turbine control. An on-board identification chip enables automatic board recognition and built-in diagnostic functions. The PCB is conformal coated to defend against dust, humidity and vibration inside power plant control cabinets.
