Product Description

The VT-VSPA1-2-1X-V0-0 is a Bosch Rexroth valve amplifier. It is designed for use with the following direct operated proportional pressure valves: DBET-6X, and DBEM...-7X. The VT-VSPA1-2-1X-V0-0 is an analog amplifier in Euro-card format. The front panel of the amplifier measures 128 x 20 millimeters. The default value for the characteristic curve and command-value dependent frequency is active. The default value for the ramp time is 5 seconds. The default value for the pilot current is 100 milliamps. The default value for the maximum output current is 1.6 Amps. Bosch recommends amplifier assembly only when it is de-energized. Connectors with freewheeling diodes or LED displays must not be used for the solenoid connection. The command value lines must be shielded. The shielding should be connected to earth on the card-side. If system earth is not present, Bosch recommends connecting the shielding to 0 Volts operating voltage.

Bosch also recommends providing appropriate separation between power lines and solenoid conductor / signal lines. The minimum distance between the VT-VSPA1-2-1X-V0-0 and radar or aerial lines should exceed 1 meter. The VT-VSPA1-2-1X-V0-0 operates at 24 Volts DC input. The permitted input tolerance is +40% (35 Volts DC) and -20% (18 Volts DC). The maximum power consumption of the amplifier is 24 VA and maximum current draw of the valve amplifier is 2 Amps. Specifications for the analog inputs are as follows: 0 to +10 Volts for the command value 1 to 4 (potentiometer inputs), 0 to +10 Volts for the different input, 4 to 20 milliamps for the current input and 0 to +5 Volts for ramp time external. Shipping weight of the VT-VSPA1-2-1X-V0-0 amplifier is approximately 0.15 kilograms.
