• Universal in use, controlled via CAN bus 
  • Inputs and outputs with diagnostic capabilities
  • Automatic connection port detection
  • Configurable using software

I/O modules form the logical extension of control units. They increase the number of inputs and outputs or provide special functions.
They also simplify the wiring inside a mobile machine through the connection and control using the CAN bus. I/O modules are positioned close to the appropriate actuators and sensors. The position in the machine can be identified via hardware encoding; the modules can be configured using software.



We are proud of our products and solutions, but they really reveal their true colors when used by our customers. Whether digitalized, automated or electrified – mobile machines repeatedly delight with new innovations, in particular in terms of their user-friendliness, reliability and ability to integrate into work processes. Thanks to our customers, we are delighted to present a small selection here.


Our objective is to support our customers in all aspects concerning the digitalization, automation and electrification of their mobile machines. We consider the entire machine lifecycle and develop our STW product and service portfolio in alignment with this lifecycle. The ECO system, an open and holistic approach, facilitates the cross-topic integration of STW solutions. Furthermore, our product approach facilitates functional expansion through partner offers and hybrid, integrated products based on our system module.


The STW "ECO System" is characterized through the integration of systems and products which transcend the borders between solution areas. Our partners also supplement the STW product and services portfolio for the benefit of our customers. The open nature of the product portfolio permits easy integration of the products into third-party systems or the supplementation of our system through further products by third party providers.
