Logic from the construction kit: Digital and analog position monitoring can now be combined for the first time

The logic valve LC2A-1X from Bosch Rexroth allows precise position monitoring.

Active logic LC2A-1X from Bosch Rexroth with new functions

With its actively controllable 2/2 directional cartridge valves LC2A-1X in conjunction with logic covers from the standard program, Bosch Rexroth opens up a virtually unlimited variety of functions in hydraulics. Thanks to the integration of an analog sensor in addition to digital position monitoring, users can exactly sense and evaluate the valve position. The modular structure reduces the engineering and assembly effort as well as cost of circuit modifications and repairs.

Analog position sensing not only allows the switching behavior to be evaluated during operation or when optimization tasks are carried out. Also position-controlled tasks can be realized with a proportional adjustment element.

Compared with position monitoring of the former variant with damping nose (option "D"), the new spool with overlap nose (option “F”) reduces the delta p Compared with position monitoring of the former variant with damping nose (option "D"), the new spool with overlap nose (option “F”) reduces the delta p by up to 60 percent depending on the size. Apart from a reduction of power losses, this allows smaller sizes to be used.

A novelty is versions for an unrestricted operating pressure of 450 bar. Due to the compatibility with standard logic inserts, series LC2A-1X is predestined for conversions – for example in the case of more stringent requirements with regard to freedom from leakage, closing time, pressure range or position monitoring. The valve series covers a size range from 16 to 100 and is designed for flow rates up to 12,500 l/min.

Economical, precise, safe, and energy efficient: drive and control technology from Bosch Rexroth moves machines and systems of any size. The company bundles global application experience in the market segments of Mobile Applications, Machinery Applications and Engineering, Factory Automation, and Renewable Energies to develop innovative components as well as tailored system solutions and services. Bosch Rexroth offers its customers hydraulics, electric drives and controls, gear technology, and linear motion and assembly technology all from one source. With locations in over 80 countries, more than 33,700 associates generated sales revenue of approximately 5.6 billion euros in 2014.

Steel, rubber and oil – digital?! Industrial hydraulics must pick up the pace on the way to the digital future

Industrial hydraulics – today, this largely amounts to standard hydraulics consisting of iron, rubber, oil and, maybe, 24V connection sockets. At the same time, Industry 4.0 and the Internet of Things are changing the face of the factory floor: Decentralized intelligence, integrated sensor technology and connectivity have already become key requirements for many industrial applications. Nonetheless, hardware-intensive industrial hydraulics is in a position from which it can smoothly glide into this new digital environment. The requirement: Hydraulic manufacturers must accept the challenge of intensively advancing digitalization.

Software of the future: Freed from …

…the restraints of hardware – the software of the future. In the factory of the future, machine modules and processing stations will be regularly reorganized, flexibly take on new tasks and retrieve the appropriate software function. This change has already begun: Machine manufacturers are already able to install identical control functions on various device platforms without any extra effort. Here is an overview of concepts for today and tomorrow:
