Configurable I/O module

The IO318 is a flexible, cost-effective, and configurable I/O module with 32 differential digital lines.

You can expand the IO318 capabilities with Speedgoat’s rear plug-ins for digital lines or additional functionalities such as resolver measurement.

The IO318 I/O module comes with a Speedgoat configuration file containing all of the required functionality and is ideal for closed-loop controls and hardware-in-the-loop (HIL) simulations using MATLAB® and Simulink™.

Key Features

  • 32 x RS422 differential front I/O lines
  • 64 x rear I/O lines
  • Configurable workflow for Simulink Real-Time™ supported by Speedgoat configuration files and the Speedgoat I/O Blockset
  • Simulink Real-Time driver blocks for FPGA code modules

Front I/O 32 x RS422/RS485 differential front I/O lines. The direction is software configurable for each line
Rear I/O 64 x rear LCMOS, 3.3V or 32 LVDS, or a combination of it on P14
Mean time between failures (MTBF)* 320,000 hours
MTBF (Mean Time Between Failure) - MTBF values shown are based on calculation according to MIL-HDBK-217F and MIL-HDBK-217F Notice 2; Environment: GB 20°C. The MTBF calculation is based on component FIT rates provided by the component suppliers. If FIT rates are not available, MIL-HDBK-217F and MIL-HDBK-217F Notice 2 formulas are used for the FIT rate calculation.
