VT 2000 Proportional Amplifiers
The VT 2000 Proportional Amplifier series provides Eurocard-format control electronics for proportional pressure valves that do not use electrical position feedback. These cards are used with direct-operated and pilot-operated pressure-control valves, driving the valve solenoid through a clocked current output stage. Command input can come from a 0 to +10 V differential signal or from an external potentiometer using the amplifier’s internal regulated +9 V reference. The amplifier combines the command sources, applies a maximum-command limit from the front panel, and then routes the signal through a ramp circuit with separate up-ramp and down-ramp adjustments. Selectable ramp ranges allow the response to be matched to the hydraulic system, while a short minimum ramp setting can be used when faster reaction is needed. A bias-current adjustment and selectable dither frequency help tune solenoid behavior and improve proportional valve response. For setup and service checks, the card includes test points for command value and actual current. The VT 2000 series operates from a 24 VDC supply and includes reverse-polarity protection for the supply connection and short-circuit protection for the solenoid wiring.
