These cards are designed to control pilot servo valves without inductive LVDT feedback. They are intended to be used for closed-loop applications. These electronic amplifier cards comprise 32 pins for installation in Euro card holders. The amplifier cards are often modified for power supply, application and valve type. They convert the input signal to a proportional current for the associated torque motor that regulates the pressure balance of the pilot valve.

VT-1600 electronic amplifier cards encompass three internal potentiometers that can be accessed through their front plates. They incorporate a proportional, integrator and derivative control circuit that supports the optimal tuning of constant velocity circuits and position control. These Rexroth amplifier cards have a few internally connected terminals to which external connections cannot be made. The cards are lightweight and weigh only around 0.15kg. These amplifier cards can be connected to a +/-15V regulated supply voltage with the voltage regulators removed. We can offer assistance in getting industrial automation lines up and running by maintaining normal operating standards.

• VT-1600 electronic amplifier cards have a power supply current of less than 200mA. They feature output current ratings of +/-60mA and +/-100mA.
• The Rexroth cards have a compact size of 100 x 160 mm that allows them to be used in confined spaces or where there is a space constraint.
• This series of amplifier cards have high quality and depict a power supply voltage of +/-22 V to +/-28 V with the voltage regulators installed.
• These electronic amplifier cards have a relay with a duty cycle of 1 ms, a nominal coil resistance of 2000 Ohms and a relay coil voltage of 22 V to 28 V.
• The amplifier cards have control inputs for use with UK 2 or VE 102 system cards that increase the control capabilities beyond the standard PID closed loop.

VT-1600 electronic amplifier cards have an ammeter mounted on their front plates for quick reference of the current to the valve. The cards also encompass a voltage stabilizer for providing clean voltage to ensure stable and consistent performance.

The amplifier cards support an ambient operating temperature ranging between 0 °C and 50 °C. They are meant to be stored between -20 °C and 70 °C. The front plate has a height of 5.05 inches, corresponding to three units, a width of 0.20 that is equivalent to one division on the solder side and a width of seven divisions on the component side.
