Detailed Functional Description
The primary function of the GE IS200WETBJ1ABA involves conditioning and routing signals between field devices and the Mark VIe controller. Specifically, it accepts analog signals from transmitters, thermocouples, or position sensors and converts them to digital values for the control system. Simultaneously, it receives digital commands from the controller and drives output relays or analog setpoints to actuators. The board performs signal filtering, linearization, and scaling to ensure accurate representation of process variables.
