The VT-VSPA1K-1-1X-002-60SEC is an innovative valve amplifier from Bosch Rexroth, designed for regulating proportional pressure control valves in hydraulic and electrical systems without electrical position feedback. This model allows for separate upwards and downwards adjustments thanks to its adaptable ramp generator and features a switchable, differential input from voltage to current. Functioning on a nominal 24V DC voltage, with a variance of +40% to -5%, it employs a single solenoid as the actuating element, and a ramp time setting of 30 ms to approximate 1 second or 5 seconds. The VT-VSPA1K-1-1X-002-60SEC is engineered as a robust Eurocard PCB, following DIN 41494 specifications, sporting a width of 100mm and length of 160mm. For user convenience, real-time operation feedback is provided by embedded LEDs, aiding in fault identification. The unit also includes protective features such as cable break detection for the 4 to 20 mA current input, reverse polarity protection for voltage supply, short-circuit protection, and cable break detection for the solenoid conductor. It's designed to operate at ambient temperatures between 0°C and +50°C.
