The VT-VSPA1-2-1X-V0-A4 is an industry-leading analog valve amplifier produced by Bosch Rexroth. This integral device allows for direct control of proportional pressure valves and features an innovative power supply unit with a current limiter. Protection measures include reverse polarity and short-circuit protection. The differential input is rated at 0 to +10 volts, and it has a current input rating of 4 to 20 milliamps. Operating optimally at 24 volts DC, it can tolerate input voltages between 18 and 35 volts. With a maximum power and current consumption of 24 VA and 2 Amps respectively, its clock frequency operates at a consistent 250 Hertz. The wide-ranging amplifier outputs can differ from 0 to +10 Volts, with the 'ready for operation' signals varying between 16 volts ('high') and less than 1 volt ('low'), a regulated voltage of +10 volts, and power output stage of 0 to 1.9 Amps. Its 48-pin male multipoint connector provides reliable operation. Weighing just 0.15 kilograms and measuring at 128 x 20 x 165 millimeters, the compact Euro-card formatted amplifier functions best within a temperature range of 0 to 50 degrees Celsius for operation and -25 to 85 degrees for storage.
