Bosch Rexroth’s digital onboard electronics for hydraulics require no fieldbus

Bosch Rexroth has introduced newly developed digital onboard electronics for hydraulics that allow economical scaling between analog components and those with a fieldbus/Ethernet connection. They use no additional cabling and provide the open interfaces Bluetooth and IO-Link. In conjunction with a suitable app, commissioning engineers, operators, and service technicians can access components and change parameters directly using a smartphone, independent of the machine control system.

The first components to feature the digital onboard electronics are the new proportional pressure-regulating valves. They offer improvements such as volume flow-independent pressure regulation and a linear command value-pressure characteristic curve with four pressure levels. The valves have an integrated pressure sensor, as well as a connection for external pressure sensors.
