The IS200DSPXH2C is a Digital Signal Processor Control Board manufactured and designed by GE as part of the EX2100 Series used in GE Drive Control Systems.

The IS200DSPX Digital Signal Processor Control Board (DSPX) is the primary controller for the bridge and motor regulator and gating functions for Innovation Series drives.

It also controls generator field control functions for the EX2100e Excitation Control. The board provides logic, processing, and interface functions.

The DSPX board includes a high-performance digital signal processor (DSP), standard memory components, and an application-specific integrated circuit (ASIC) that performs custom logic functions.

An inner loop load pulse signal captures the values of I/O such as bridge, motor, or generator voltages and current VCOs, tachometer counters, and discrete inputs. It can also synchronize the ISBus channels, the software, and gating outputs to bridges.

At a sub-multiple or multiple of the inner loop load pulse, an application loop load pulse signal is used to capture values of other application VCOs and optionally the tachs.

Stack overflow detection is provided for both the foreground stack (from internal memory) and the background stack (from external SRAM). Interrupt INT0 is generated if either stack overflows. If both stacks overflow, a hard reset is generated.
