GE IS230STAOH2A Mark VIe Analog Output Terminal Board in stock
GE IS230STAOH2A is an analog output terminal board for GE Speedtronic Mark VIe turbine control system. It receives digital control data from the Mark VIe controller and converts digital signals into standard analog current signals to drive field actuators, valve positioners and control elements in power generation turbine units.

This board adopts 16 galvanically isolated analog output channels with high precision, supporting 4-20mA signal. It has conformal coating and built-in channel fault diagnosis, with front LED indicators for status monitoring. It is widely used as spare replacement parts for gas and steam turbine control cabinets.
