Blog về Speedgoat Launches Highprecision IO11320 Module for Realtime Control

Engineers grappling with the limitations of analog signal output in real-time control and hardware-in-the-loop (HIL) simulation systems now have a powerful solution. Speedgoat's newly launched IO113-20 20-bit high-precision analog output module delivers unprecedented accuracy, speed, and flexibility for complex system designs.

In demanding real-time applications, even minute signal deviations can compromise system performance. The IO113-20 module's standout feature is its 20-bit output resolution, enabling precise voltage signal generation (±10V, ±5V, or ±2.5V). This level of control proves indispensable for accurate sensor feedback simulation, actuator response emulation, and complex control algorithm output in HIL simulations and rapid control prototyping.

The module employs an R-2R weighted digital-to-analog converter (DAC) architecture that ensures independent high-precision output across all channels while minimizing signal latency for real-time responsiveness.

Addressing modern engineering requirements, the IO113-20 features eight independent, synchronously clocked output channels with sampling rates up to 500 KSPS. Coupled with a 256K-sample independent FIFO data buffer, the module effortlessly handles high-dynamic, fast-changing signal output demands.

Whether operating in continuous output or burst mode, the IO113-20 maintains stable data flow, capturing critical transient information during high-speed dynamic testing and simulation scenarios.

The module offers exceptional flexibility with configurable output channels. Users can set up the eight analog output channels as:

• Eight single-ended outputs
• Eight 3-wire differential outputs

This adaptability accommodates diverse wiring environments and signal isolation requirements. Additionally, eight bidirectional TTL digital I/O lines expand integration possibilities, configurable as either inputs or outputs.

The IO113-20 incorporates on-demand auto-calibration to maintain long-term stability. This feature automatically detects and compensates for output channel errors, ensuring optimal performance. For single-ended output mode, remote ground sensing minimizes ground loop errors, enhancing signal purity.

Designed as a PCI Express short card, the IO113-20 integrates seamlessly with Speedgoat real-time target machines. With typical power consumption of 9.4W (maximum 11W), it operates efficiently within standard (0°C to 70°C) or optional extended (-40°C to 80°C) temperature ranges for industrial and laboratory applications.

The module features a 68-pin SCSI3 connector with compatible cables and terminal boards for rapid deployment.

The IO113-20's performance characteristics make it ideal for:

• Rapid control prototyping (RCP) - accurately simulating controlled object output signals
• HIL simulation - realistically emulating complex system outputs (vehicles, aircraft, industrial equipment)

Speedgoat offers complementary accessories including:

• IO113-ExtTemp for extreme temperature operation
• IO113-BNC-Panel/Box for convenient BNC interface connectivity

The IO113-20 establishes new benchmarks for analog output modules in real-time control and HIL simulation, combining precision, speed, and reliability for advanced engineering applications.
