The amplifier modules are suitable for the control of a proportional solenoid. They are snapped onto top hat rails according to EN 60715. The electrical connection is established via screw terminals. The modules are operated at 24 V direct voltage.
The solenoid current (actual value) is measured and compared to the externally provided command value. Any occurring differences between actual value and command value, e. g. caused by a change of the solenoid temperature or the operating voltage, are compensated.
The activation of the solenoid control is indicated by LED “H3”; its brightness is proportional to the solenoid current.
Using one trimming potentiometer each, the following can be set from the outside:
a separate ramp time for upwards and downwards ramp (via R11, R12 → tmax approx. 5 s)
the incline of the output characteristic curve (via R1, R2)
