Chopper amplifier (for mounting in control cabinet), 24 V DC, for proportional control valve »posiflow«, Temp. range -10°C to 60°C
For converting the 0 to 10 V, 0 to 20 mA or 4 to 20 mA standard signal (settable) to an impressed current (0 to 1 A).
The impressed current is pulse width modulated to ensure low-hysteresis, thermally stable control.
With settable time ramp (ON/OFF, 0.1 to 3 s).
The minimum and maximum supply current for the solenoid can be set according to the control signals.
