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.

Largest flow on the market

Rexroth is raising the bar in performance and communication for hydraulic actuators with its new generation of WRC-4X directional cartridge valves. The valves are more dynamic and consistently achieve flows that could previously only be achieved with the next highest available size. Integrated electronics (OBE) allow the new valve series to be networked via open interfaces with higher-level control units and Industry 4.0 environments even when under analog control. This means that valves can already be integrated into forward-looking automation concepts today.

Rexroth offers digitalization of analog interfaces in hydraulics via IO-Link

Reduced connection costs at increased availability: Rexroth harnesses the advantages of the IO-Link open standard also for hydraulic actuators and sensors. As of now, 4WRPEH proportional control valves and HEDE10 pressure switches are available with IO-Link interfaces. Connection is realized via the decentralized and quick IP67 I/O system S67E IO-Link Master. This offers users direct access to the field bus and all data provided by the actuator/sensor.
