AMP08D is amplifier for controls of hydraulic proportional valves with two solenoids. Depending on the polarity of the input reference is operated one of the two solenoids of the valve, and depending on the value of the reference is regulated current through the respective solenoid.
The main features of AMP08D are :
There are provided 5 multiturn trimmers :
–ramp - It adjusts the length of the leading/ trailing edge of the output current to reach the reference.
For each solenoid have two trimmers for setting the current:
- Z - It adjusts the current at the minimum value of the input reference
- G - It adjusts the current at the maximum value of the input reference.
These two trimmers allow adjusting the steering zone of the valve. The output current of the amplifier is given by:
y - is the output in percentages;
x - is the input in percentages;
G – is the value from trimmer G- number from 0,5 to 1
Z - is the value from trimmer Z- from 0% to 50%.
LEDs for status indication are 4:
-POW - lights when the power supply voltage is between working limits
-O1 – lights when is controlled output 1 of amplifier
-O2 – lights when is controlled output 2 of amplifier
-EN/ERR – lights green (when on terminal EN is applied voltage for enabling of the amplifier and input voltage is between ±0,1V and ±10V) or lights red (when on terminal EN the voltage is bellow min limit or input voltage is outside ±0,1V ± 10V).
AMP08D is for DIN mount and can be used to control valves up to 60W.
