2 Characteristics

This power amplifier is used to control proportional valves with one solenoid. The compact solution is imple-
mented in an inexpensive IP-65 housing.
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.
The parameterization can be done via the PC interface and the ULA-310 adapter or internally via the UP and
DOWN buttons.
By the free parameterization of the power amplifier all typical proportional valves of the different manufactures
can be optimal adapted.
Typical applications: Controlling of the solenoid of proportional throttle or pressure valves.
