Page 6: Characteristics
2 Characteristics This amplifier plug is used to control proportional valves with one solenoid. The compact and inexpensive so- lution will be mounted directly on the solenoid. A typical input signal of 0… 10 V (optional 4... 20 mA) can be used. The output current is closed loop con- trolled and therefore independent from the supply voltage and a varying solenoid resistance. -
