GE IS200DSPXH1DBD

Product Features

GE IS200DSPXH1DBD can be equipped with a powerful dedicated digital signal processor that provides floating-point computing power and high clock speeds.

Its core function is to acquire, condition and analyze signals from vibration sensors such as accelerometers, velocity sensors, eddy current sensors Keyphasor.

GE IS200DSPXH1DBD performs Fast Fourier Transforms (FFT) to convert time-domain vibration signals into frequency-domain signals for identifying characteristic frequencies (e.g., rotor unbalance, misalignment, bearing faults, blade passage frequencies, etc.).

GE IS200DSPXH1DBD enables vibration protection logic (e.g., set point comparison, alarms, trips) and typically meets the requirements of standards such as API 670. Multiple channels of vibration signals can be processed.

GE IS200DSPXH1DBD can process RPM reference signals (Keyphasor) for synchronized sampling, order tracking and phase measurement. Supports high sampling rates to accurately capture vibration waveforms.

Communicates with a host controller (e.g. IS200ERBH) in a Mark VI rack via the VME64 or VME32 bus to receive commands, configure parameters and upload processing results/alarm status.

GE IS200DSPXH1DBD contains RAM (for data processing) and ROM/Flash (for firmware/program storage). It has LED indicators to show power status, operation status, fault status and communication status.

GE IS200DSPXH1DBD can receive vibration sensor signals and Keyphasor signals via on-board high-density connectors (e.g. D-Sub or DIN type).

Product Using Principle

GE IS200DSPXH1DBD signal inputs are signals from vibration sensors mounted on the turbomachinery, as well as the Keyphasor RPM reference signal, which are connected via dedicated cables to the I/O connectors on the front of the board.

GE IS200DSPXH1DBD signal conditioning is the on-board analog front-end circuitry that conditions the weak input signals, including filtering (anti-aliasing), amplification/attenuation (gain adjustment), and IEPE sensor excitation (if applicable). The conditioned analog signal is converted to a digital signal by a high-speed, high-resolution analog-to-digital converter (ADC).

GE IS200DSPXH1DBD digital signal is fed to the on-board DSP core, which performs the core algorithms of FFT analysis of the vibration signal and calculation of the frequency spectrum (amplitude, phase). The Keyphasor signal is processed to calculate the rotational speed and phase angle for synchronized sampling (order analysis).

Calculates overall vibration values (Peak, RMS, Pk-Pk), band-specific amplitudes, phases, and compares to user-set alarm and trip setpoints. Other advanced diagnostic algorithms may be performed.

The results of the DSP processing (spectrum data, alarm status, trip status, process values, etc.) are transmitted over the VME bus to a master controller (e.g., IS200ERBH) in the Mark VI rack.

The host controller interacts and is responsible for configuring the parameters of the DSPX board (sample rate, gain, alarm setpoints, filter settings, etc.). Receive processed data and status information from the DSPX board. Integrates vibration data, alarms, and event logs throughout the Mark VI HMI/control system (e.g., CIMPLICITY, ToolboxST) for operator review and diagnostics.
