I/O Expansion Modules

Expansions or modifications to machine functions must not be achieved by re-designing the machine. The preferred option is to use controllers, therefore, which enable quick and uncomplicated expansion of on-board electronics, based on their internal interfaces. This means that it must be possible to incorporate, with the minimum outlay, inputs and outputs which were not provided in the basic version of a machine, into the present machine control.

HYDAC I/O Expansion Modules meets this requirement for additional inputs and outputs with its simple-to-integrate I/O expansion modules. The manufacturers of machines using HYDAC control technology are therefore not restricted in terms of expanding the functions of their products in the future.

The communication and integration of the expansion modules takes place via CANopen. It enables their inputs and outputs to be configured and parameterized via the control configuration of the available controller in a simple and uncomplicated way.

HYDAC Expansion Modules for a variety of applications

The versions of the I/O expansion module provide additional varied PWM outputs with internal current measurement and an integrated PID control device, alongside numerous powerful switch outputs. These permit proportional controls to be implemented very simply.

The detection of digital switch and analog current/voltage signals is possible using digital and analog inputs which can be parameterized differently.

The HY-TTC 30X series of I/O expansion modules provides an outstanding power balance combined with extremely compact design. The particularly powerful PWM outputs offer the possibility of driving valves, such as PVG valves, using on-board electronics directly via proportional voltage outputs. Generally speaking, this series of instruments offers great flexibility and electrical power and can therefore provide the optimal solution for almost all common tasks. Of particular note are our I/O expansion modules with increased functional safety which include both the well-proven HT-TTC 48XS and HY-TTC 30XS series.

The 30XS-H version has been optimized for system expansion to include additional hydraulic functions. These modules combine the advantages of decentralization with simultaneously secure signal processing and control. This combination represents something entirely new in the mobile controller market
