The VT 2000-52-A is a proportional amplifier card in the VT-2000 Series by Bosch Rexroth Indramat. This sophisticated device functions by converting the input voltage signal evenly into an output current, allowing it to power a proportional solenoid. The force exerted on the valve's pilot poppet will fluctuate depending on the current supplied to the solenoid, which consequently results in a variable pressure. The amplifier card relies on the input voltage supplied by the power source on its 18ac & 24ac pins. This voltage is then regulated, filtered, and smoothed. The card also has a voltage output of 18 V which is divided on pin 16ac & pin 10ac. Pin 14ac has a zero reference potential measurement. By manipulating the +9 volts from pins 10ac & 14ac using a potentiometer, simple relays, or reed switches, the voltage can be controlled externally. Pin 12ac serves as command input for the amplifier. Moreover, the VT 2000-52-A can process a differential analog input through pins 30ac & 28ac, which is then compared in a differential amplifier. To regulate the pressure, trim pots 'R1' and 'R2' can be adjusted, with 'R1' controlling the lowest pressure or bias current, and 'R2' controlling the highest pressure or uppermost current. It should be emphasized that the 'R1' adjustment should be made prior to adjusting 'R2'.

VT 2000-52-A by Rexroth, Indramat, Bosch in the VT-2000 Series. The VT-2000 is a proportional amplifier suitable for controlling single solenoid pressure control valves without electrical position feedback. This VT 2000-52-A offers a Name Plate of Factory Assigned, Pulse Frequency of 100 Hz or 200 Hz; + or - 10 % each, a Operating Voltage of 24 VDC + 40 % - 5 % and a Connection Type of 32-pin male connector, DIN 41 612, form D.
