As the exclusive representative of W.E.S.T. Elektronik GmbH on the Czech and Slovak markets, we sell, provide technical support, customers training and commissioning of amplifiers and controllers for hydraulic proportional and servo valves
W.E.St. Elektronik GmbH is German company developing and producing amplifiers, positioning modules, pressure and pump control modules for proportional and servo hydraulic valves.
for all types of proportional valves of different manufacturers. Amplifiers are available either as a plug for direct mounting on the valve for both single- or two solenoid version or as a DIN-Rail modules for installation in control cabinet. Please refer to the catalogue below.
Compact amplifier for control directional valves with two magnets. Amplifier in connector housing is mounted directly on the valves.
● Input signal 0..10V (optionally 4 .. 20 mA)
● The output current is regulated independent of supply voltage and solenoid resistance
● Parameters can be se via PC and ULA-310 programming adapter or optionally via USB 2.0 mini, which is integrated in housing.
● RAMP, MIN, MAX, Dither frequency and amplitude, PWM frequency can be programmed. In addition, the valve characteristic curve can be linearized using 10 corner points
For controlling of single solenoid proportional valves as well as general inductive loads.
● inexpensive IP 65 housing
● input signal 0..10V (optional 4..20mA)
● Output current is closed loop controlled independent of supply voltage and solenoid resistance.
● Parameters can be se via PC and ULA-310 programming adapter or via UP and DOWN buttons
Control of directional throttle and pressure valves, which need a flexible adaptation of the solenoid control. Suitable for all typical proportional valves of different manufacturers REXROTH, BUCHER, DUPLOMATIC, PARKER etc.)
● Control of one directional valve with two solenoid or one/two independent pressure or throttle valves with one solenoid each.
● Setting via WPC-300 programm
Module prepared output signal for amplifier stage. Input signal can be provided as digital signals or analog signal (event. by potentiometer). Advantage against common PLC programm is extremely fast processing in a1ms cycle. Module can be equipped with amplifier stage.
● DSG-111, 16 values selectable by 4 DI with relating ramp times, 1AI signal with own ramp can be also used.
● DSG-112 universal programmable with simple structure script. Closed loop control functions possible, PI controller integrated.
● DSG-164 analog signal generating of demand values by digital inputs. Setting via potentiometer.
● MDR-339-P-IO pressure control modules for general use with pressure valves and integrated power stage. Sensor signals, parameterisation or diagnostic data possible via IO link. Automatic commissioning assistant.
● MDR-337-P pressure control with integrated power amplifier and automatic commissioning
● PID-131-U standard PID controller designed as PID compensator. Ouput signal as differential signal for direct connection of OBE valves with integrated electronics.
● PQ-132-U p/Q controller, pressure limitation controller for hydraulic axes
● MDR-133 pressure control with pressure relief valves or reducing valves
● SCU-138-P speed control unit with integrated power stage
offer solution for both closed and open loop displacement control with additional pressure control. Load limit control is also possible.
● PQP-171-P universal pump control module
● PQP-176-P universal pump control module for swivel angel, pressure and power control
● PQP-179-P-PFN universal pump and valve control module for controlling of pressure, swivel angle, power and valve positions via PROFINET
● PQP-179-P pump control module for the open or closed circuit with integrated power stage
From bypass control to multi-axis synchronizing and positioning control with Profibus and CAN Bus
● CSC-158-U-SSIC Axis control system with synchronisation
● UHC-126-U-S2 Axis control module with universal positioning, pressure limitation and fieldbus interface.
● CSC-151 synchronization control module of two cylinders in bypass.
● POS-124-U two axis positioning with ProfiNet IO, Profibus DP and SSI sensor interface
● CSC-156-U-SSIC+PCK-306 synchronization with pressure limitation, SSI, Profibus interface for 2 to 4 axes.
