The GE IS200BPPBH2B IS200BPPBH2BEB analog I/O processor board handles analog signal processing for Mark VI systems. This board converts field sensor signals into digital data for the main controller. You will find this processor board in Speedtronic Mark VI control cabinets. Its high-resolution design ensures accurate measurement of critical turbine variables.
Analog Processing Architecture
This analog I/O board provides eight differential analog input channels. Consequently, it rejects common-mode noise from long field wiring. The GE IS200BPPBH2B IS200BPPBH2BEB also includes four analog output channels for actuator control. Moreover, a 16-bit ADC delivers high measurement resolution. You can configure each channel independently via software.

Input Filtering and Output Drive
The unit includes programmable low-pass filters on each input channel. Therefore, it rejects high-frequency noise from industrial environments. This board replaces the IS200BPPBH2BEB version without any calibration changes. Simply remove the old board and install this one. GE designed this processor board for single-slot installation. Hence, it fits directly into existing Mark VI rack positions.
Six PCB layers separate analog and digital signal paths effectively. Three connectors handle all field wiring and backplane communication. The GE IS200BPPBH2B IS200BPPBH2BEB includes a precision voltage reference for self-calibration. Accordingly, it maintains accuracy over temperature and time. This feature ensures stable readings from thermocouples and pressure transmitters.
Calibration and Field Wiring Guide
You must perform an auto-calibration routine after installing this board. The onboard reference provides 2.5V and 5V for gain verification. The GE IS200BPPBH2B IS200BPPBH2BEB stores calibration constants in non-volatile memory. Consequently, it retains settings even after power loss. Two status LEDs indicate board health and communication activity.
Always use shielded twisted-pair cable for analog input wiring. Connect the shield only at the board end for best noise rejection. The GE IS200BPPBH2B IS200BPPBH2BEB works with all GE Mark VI control systems. Proper grounding of analog commons prevents ground loop errors. This board operates reliably in non-condensing environments only.
