VT-VSPA1-10-1X-V0-0

Product Description

The Bosch VT-VSPA1-10-1X-V0-0 is an analog valve amplifier. It is available in a euro-card format. The amplifier is suitable for controlling proportional pressure valves. The differential input on the amplifier accepts 0 to 10 Volts DC. The current input on the amplifier is rated for 0 to 20 milliamps. The amplifier also feature a ramp generator with separately adjustable up/down ramp times. Short-circuit protection and cable break detection are supported for the solenoid conductor. The VT-VSPA1-10-1X-V0-0 amplifier has a power supply unit with a making current limiter. This unit supplies all internally required positive and negative supply voltages. LED lamps are available on the front panel for the following indications: “ready for operation”, enable, ramp activated, zero point calibration, amplitude attenuator, ramp up and ramp down. A 2-Amps rated safety fuse with medium time-lag is provided as a safety device.

Operating voltage for the VT-VSPA1-10-1X-V0-0 amplifier is 24 Volts DC. The upper voltage limit is +35 Volts DC, and the lower voltage limit is 18 Volts DC. Power consumption of the VT-VSPA1-10-1X-V0-0 does not exceed 24 VA. The current consumption does not exceed 2 Amps. The type of connection on the VT-VSPA1-10-1X-V0-0 is a 48-pin male multipoint connector compliant with DIN 41612 design F. The Euro-card dimensions of the VT-VSPA1-10-1X-V0-0 are 100 x 160 millimeters. The working temperature range is 0 to 50 degrees Celsius. The storage temperature range is -25 to 85 degrees Celsius. The net weight of the VT-VSPA1-10-1X-V0-0 is 0.15 kilograms. Operators should only handle and assemble the amplifier when it is powered-off. Only instruments with input resistance exceeding 100 kiloohms should be used for making measurements. Distance between the VT-VSPA1-10-1X-V0-0 and radar or aerial systems should be more than 1 meter.
