This electronic module was designed to control hydraulic proportional valves. 16 programmable demand values and relating ramp times are selectable by four digital switching inputs (binary coded). Additionally, a scalable analog command input with own ramp function is available, too. Alternatively, a 4Q-ramp can be parameterized. The ramp generator is realized with optional jerk limitation which allows flexible adjustments depending on the applications and soft behavior. A programmable function allows linking the analog input signal and the internal demand values together by different mathematical operations. This module is adaptable to nearly all proportional valves by deadband compensation as step function for characteristic linearization. Proportional valves with integrated or external electronics can be controlled by the universal analog output of the standard device. For controlling valves without electronics, the extended version with power stage is provided.

DSG-112

Freely configurable control module, alternatively with power output stage

Typical applications:

  • Rapid/creep speed controls
  • recallable speed or pressure setpoints
  • characteristic curve adjustments and signal range monitoring
  • time-controlled motion sequences
  • setpoint presets
  • general control functions

This electronic module was developed as a universal control module. Its fast signal processing makes it ideal for hydraulic drive technology, but it can also be used universally in other industries and technologies.

The script-based programming is much easier to handle than a PLC programming language and allows typical requirements to be realised in the most compact way.

Further advantages are:

– Extremely fast processing in a 1 ms cycle
– Very simple structure of the commands, fast learning process
– Possibility of offline simulation of scripts even without hardware
– Closed loop control functions are possible, PI controller integrated

DSG-164

Demand signal module

Typical applications:

  • analog generating of demand values by digital inputs

Via four digital inputs, four by potentiometer adjustable demand values can be selected. For the supply of external potentiometers a reference voltage (10 V) is available. Another digital input allows switching the polarity of the output signal. Only one value can be active at the same time. If more than one input is activated, the highest priority is selected. If there is no input activated, an external voltage signal can be connected through to the output. This feature enables cascading of those modules.
