VT-VSPA1-1-D10 Image 1


The VT-VSPA1-1-D10 is a valve amplifier in the VT-VSPA Series by Bosch Rexroth Indramat. Equipped with a ramp generator and a clocked power output edge, it assists in detecting cable breaks in the solenoid conductor while offering protection against short circuits. Also included in its design is an additional non-isolated command value input in 0 to 9V range. The unit is mountable on a 100 x 160mm Euro-card and connectivity is facilitated through a D-design male 32-pole multipoint connector. The ramp generator is built for adjustability in both downward and upward directions with a minimum ramp time of 30ms. To generate an output signal, the amplifier uses a stepped input signal, which is subsequently forwarded as a current command value to a summing amplifier, within a range of 0 to 6V. A readiness indicator, the H2 LED, illuminates upon a displayed "Ready-for-Operation" message if the output stage is not overloaded and will turn off in the event of a detected short circuit. Preferred applications for the VT-VSPA1-1-D10 include pilot and direct-operated proportional pressure valves with a single solenoid for the actuator. The unit has a maximum power consumption of 50VA. Depending on the settings of the DIL switch and potentiometer, the output stage's solenoid possesses either 19.5 or 5.4 Ohms of resistance, correlating to maximum current ratings of 800mA and 1,600mA respectively. Additionally, it can support a clock frequency of either 100Hz, 200Hz, 300Hz or 370Hz with a +/-10% in each case as per the switch's settings. However, proper functioning of the valve amplifier requires correct connection of the solenoid, external potentiometer, and differential input.

VT-VSPA1-1-D10 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-VSPA1-1-D10 offers a Component Series of 10, Additional Functions of Factory Assigned, and a Operating Voltage of +24 VDC + 40 % - 5 %. Other features include a 32-pole male multipoint connector and front plate of Connection Type and a Operation Control For pressure valves.
