The GE IS200EAUXH1A IS200EAUXH1ABB auxiliary control board provides supplemental I/O for Mark VI systems. This board handles additional analog and digital signals beyond the main processor capacity. You will find this auxiliary board in Speedtronic Mark VI control cabinets. Its compact design adds I/O points without consuming multiple rack slots.
Mixed I/O Architecture
This auxiliary control board features eight analog input channels with 16-bit resolution. Consequently, it reads pressure, temperature, and flow transmitters accurately. The GE IS200EAUXH1A IS200EAUXH1ABB also includes eight configurable digital I/O channels. Moreover, a dedicated microcontroller manages all signal processing locally. You can configure each channel independently through software.

Local Processing and Filtering
The unit includes a dedicated microcontroller for local signal processing. Therefore, it reduces the main CPU’s workload significantly. This board replaces the IS200EAUXH1ABB version without any configuration changes. Simply remove the old board and install this one. GE designed this auxiliary board for single-slot installation. Hence, it fits directly into existing Mark VI rack positions.
Six PCB layers separate analog, digital, and power traces effectively. Three connectors handle all field, backplane, and status signals. The GE IS200EAUXH1A IS200EAUXH1ABB includes programmable filters on analog inputs. Accordingly, it rejects 50/60 Hz noise from industrial environments. Eight LEDs show the state of each digital channel clearly.
Configuration and Installation Guide
You can configure analog input ranges individually through software. No jumpers or hardware changes are required for setup. The GE IS200EAUXH1A IS200EAUXH1ABB works with all GE Mark VI control systems. Always use shielded cable for analog input wiring longer than 10 meters. Proper grounding of analog commons prevents measurement errors.
Digital outputs can drive relays, solenoids, and indicator lamps. Each output includes short circuit protection for reliability. The GE IS200EAUXH1A IS200EAUXH1ABB delivers reliable auxiliary control for turbine systems. Installation requires only a screwdriver for terminal connections. This board operates reliably in non-condensing environments only.
