Power Amplifier f. Pressure-/Flow Valves  
Installation Manual  
Series EC106  
Electronic module for the control of proportional  
pressure or flow valves.The pressure-/ flow values  
are given by externally supplied command signals  
and internal ramp potentiometers.  
Features  
Processing and amplification of externally sup-  
plied positive commands into output signals for  
the control solenoid.  
Up to 6 independent channels for the control of  
up to 6 valves.  
Each channel is equipped with a slide switch for  
selection of pressure or flow valve operation.  
Ramp function  
Pulsed low loss amplifier power stages with  
supportingconstantcurrentcontrolforconstant,  
temperature independent solenoid forces.  
Dither generator with applied frequency to  
improve static characteristics.
