VT-VSPA1K-1-10C Image 1


The VT-VSPA1K-1-10C is a valve amplifier in the VT-VSPA Series by Bosch Rexroth Indramat. This device features a differential input that can be switched between voltage and current input. The command value is regulated through an external command value potentiometer at 9 V, and an internal potentiometer helps maintain the desired maximum pressure. The device also features a secondary command value input with voltage ranges of 0 to +10V, and current ranges of +4 to +20 mA or 0 to +20 mA, which can be configured with DIL switches. Furthermore, the VT-VSPA1K-1-10C has a ramp generator that transforms stepped inputs into distinctive ramp-shaped outputs. Its ramp times can be reduced to their minimum value through an external ramp off contact. Finally, the output signal from the generator is transported to a summing amplifier as a current command value.

VT-VSPA1K-1-10C by Rexroth, Indramat, Bosch in the VT-VSPA1 Series. The VT-VSPA1 Proportional Valve Amplifier controls solenoid current to Rexroth proportional valves without LVDT position feedback. This VT-VSPA1K-1-10C offers a Component Series of 10, Additional Functions of Factory Assigned, and a Operating Voltage of +24 VDC + 40 % - 5 %. Other features include a 16-pole terminal strip; out front plate of Connection Type and a Operation Control For pressure valves.
