  Description  

DS1103 PPC Controller Board

Powerful controller board for rapid control prototyping

The DS1103 is an all-rounder in rapid control prototyping. It can be mounted in a dSPACE Expansion Box or dSPACE AutoBox to test new control functions in a laboratory or directly in the vehicle.

At A Glance

Application Areas

The DS1103 controller board is designed to meet the requirements of rapid control prototyping and is highly suitable for applications such as:

  • Automotive controllers
  • Induction motor control
  • Robotics
  • Positioning systems and stepper motors

An integrated Infineon CAN microcontroller makes the board an attractive tool for automotive and automation applications.

 

Key Benefits

The DS1103 is an all-rounder in rapid control prototyping. It can be mounted in a dSPACE Expansion Box or dSPACE AutoBox to test new control functions in a laboratory or directly in the vehicle. Its processing power and fast I/O are vital for applications that involve numerous actuators and sensors. Used with Real-Time Interface (RTI), it is fully programmable from the Simulink® block diagram environment and all I/O can be configured graphically. This is a quick and easy way to implement and test new control functions in a real environment.

 

Comprehensive Interfaces

The unparalleled number of I/O interfaces makes the DS1103 a versatile controller board for numerous applications. It provides a great selection of interfaces, including 50 digital I/O channels, 36 A/D channels, and 8 D/A channels. For additional I/O tasks, such as multi-channel PWM, a DSP controller unit is used as a subsystem.
