Product Description

The VT-VSPA1-2-10-V0-0 is viable for controlling proportional pressure values DBET-6X, and DBEM...-7X. This value amplifier has a required differential input that ranges from 0 to +10V and its range of current input are 4 to 20mA. The ramp generator comes with separately adjustable up/down ramp times. It enables input and external ramp time presetting. Bosch Rexroth AG has carefully designed it to ensure short-circuit protection and easy cable break detection of the solenoid conductor. The VT-VSPA1-2-10-V0-0 also has a reverse polarity protection of the supply voltage.

The VT-VSPA1-2-10-V0-0 has a power supply unit with making current limiter. It supplies the required negative and positive supply voltages. The internal command value signal is measured from a total number of 6 up signals or external command value signal which are available at differential input. Following specifications apply to the VT-VSPA1-2-10-V0-0. For the standard value 0% the current input, differential input and the command value socket are 4mA, 0V and 0V respectively. However for the standard value +100% the current input, differential input and the command value socket are 20mA, +10 V and +10V.

The VT-VSPA1-2-10-V0-0 has a four command value call-ups range from w1 to w4. The external voltages with command values 1 to 4 are either defined by external potentiometers or by the voltage output +10V. All the internal potentiometer will act as limiters or attenuators while using the external potentiometer. You can only operate one call-up at a time. In case of operating several call-ups simultaneously, call up w4 has the highest priority whereas the call-up w1 has the lowest priority. The VT-VSPA1-2-10-V0-0 can only be assembled when de-energized and it weighs 0.15 kg (net).
