Electrical amplifier of EYB-D12-A-S-2X Series, ordering code:

-EYB: Electrical Yuken Double Coils Amplifier

-D24: 24VDC; D12: 12VDC; D36: 36VDC

-A: Voltage signal input 0 - 10V; B:0- 20mA current signal input; C: Pulse signal input

-S: Standard amp; G: Signal generator; F: Frequency input module; P: PWM input module

-2X: Design series

The EYB-D12-A-S-2X Amplifier for standard rail mount, used to drive a double solenoid proportional valve. Amplifier calibration valve adjustment, so that the input signal corresponds to the electromagnetic proportional valve to provide the required current. The amplifier is used for open-loop control system. Amplifier by switching current on the electromagnet, the valve to adjust the input signal (voltage or current) is proportional to, In order to guarantee the accuracy of the valve adjustment.

Installation and startup:
Recommended to pick up the order given to adjust the boot

The presetting may not satisfy the requirements of special applications in the field in turn to re-adjust the bias current, gain and slope four power but to improve its performance.
Double solenoid proportional valve, according to the diagram wiring. Must provide the voltage signal - 10V - +10 V or -5V - +5 V.

Enable:

when the EN (enable) the receipt of the enable signal (usually 24VDC ) power to the amplifier start working , the state of emergency, the enable signal set to 0 , the amplifier is cutoff .

Bias adjustment:
Input voltage 0.115V signal to the amplifier power supply, and gradually adjust the bias power , but the PT4 , until the control component movement so far.
The opposite direction to turn the potentiometer until the control component stops.

Gain adjustment:
Impose the maximum input current or voltage signal to detect whether the requirements of the maximum. Clockwise dynamic the PT3 gain increases. Counterclockwise rotation PT3 gain is reduced.

Ramp time adjustment:

Clockwise slope PT1 potentiometer, increase the ramp rise time, clockwise for slope potential PT2, increase the ramp decrease time; otherwise, shorten the time, this achieve system optimal performance.
