Products Description
GE IS200SPIDG1ABA SPID PID Control I/O Pack in stock
GE IS200SPIDG1ABA (SPID) is a local PID control I/O pack for GE Mark VIe Speedtronic turbine control system. It integrates analog input, analog output and discrete I/O, running PID algorithm locally to handle auxiliary closed-loop control of turbine units and reduce main controller computing load.
This module communicates with the main controller through IONet, supports configurable 4-20mA / 0-10V analog signals and built-in signal diagnosis. It adopts rack-mounted structure and is widely used in gas turbine and steam turbine auxiliary control loops of power plants.
