Function
(//fashionua.net)
The active connector is used for controlling proportional valves without position control.It is directly attached to the solenoid plug of the valve. The connection cable on the control side (UB, command value)is led through a gland fitting and connected.An LED signals the available supply voltage. Depending on the type of the active connector, the command value isspecified as voltage 0...10 V or as current 4...20 mA.The command value can be adjusted with regard to zero point and sensitivity. In case of voltage specification, a differential input is available.Apart from that, the command value can be led via a ramp.In order to allow for adjustment to special applications, the dither amplitude was designed variably.Upon delivery, the dither amplitude has already been set toa perfect value so that another adjustment is only necessary in the above-mentioned special cases.

The amplifier is used to control proportional valves without electrical position control.

It is connected directly to the solenoid plug of the valve. The connection cable on the control side (UB, command value) is lead through a cable gland and connected.

An LED signals the available supply voltage. Depending on the type of the amplifier, the command value presetting is a voltage 0...10 V or a current 4...20 mA.

The command value can be adjusted with regard to zero point and sensitivity. With voltage presetting, a differential input is available.

In addition, the command value can be led over a ramp.

To allow for adjustment to special applications, the dither amplitude was designed variably.

Upon delivery, the dither amplitude has already been set to a perfect value so that another adjustment is only necessary in the above-mentioned special cases.
