RapidPro SC/PS Modules

Mountable signal conditioning and power stage modules for RapidPro units

The RapidPro signal conditioning (SC) and power stage (PS) modules bring vital signal conditioning and power stage functionality to the RapidPro units. The SC modules can be installed in the RapidPro SC Unit and the RapidPro Control Unit. The PS modules are installed in the RapidPro Power Unit.

Key Benefits

A wide choice of hardware- and software-configurable modules is available that provide standard solutions in many different applications. Installing and removing the modules is easy, so the RapidPro units can be reused efficiently in different projects. Customer-specific modules will also be available on request. All the modules used with the RapidPro units are automotive-protected and can be locked safely on the carrier boards with coulter clips. This makes them suitable for in-vehicle applications. Modules are not limited in size. If complex electronic circuits require more space or pins than a single-slot module offers, modules with other form factors can be used.

Standard Modules and Custom Modules

Besides the standard modules described in the following tables, dSPACE also offers you engineering services to develop individual signal conditioning and power stage modules for your specific application scenario.
