HY-TTC 36X and HY-TTC 48X are CANopen-based, cost effective, modular and user-friendly solutions for extending the number of I/Os in mobile applications. This controllers are best suited for different kinds of control tasks in a vehicle and acts as slave unit in a CAN-based network architecture.

The intelligent I/O slave modules are used in combination with, and controlled by a master electronic control unit. The master control unit can be located at an entirely different place in the vehicle and communicates with the slave module via the standardized CANopen protocol. One or more I/O modules can be used in addition to the master control unit in a modular way. This distributed architecture makes the design and assembly of different vehicle variants possible and more cost and time effective. In addition cabling is simplified and more economic.

HY-TTC 36X and HY-TTC 48X are delivered with a ready-to-run software. The application has to be implemented for the master only and interfaces with the slave module via CANopen. This makes the setup user friendly and saves development time. Local current control on the PWM outputs of the I/O modules allow efficient control loops. The dither frequency for the valves can also be individually configured.
