The VT-VSPA1K-1-1X- SO43A-560-1 is a high-quality valve amplifier manufactured by Bosch Rexroth, for the regulation of direct and pilot-operated proportional directional pressure control valves lacking electrical position feedback. With its single solenoid actuating element, this unit utilizes a switched differential input from voltage to current. It comes with an independently adjustable ramp generator for upward and downward directions. The optimal nominal voltage rating sits at 24V DC within a +40% and -5% tolerance range, while the ramp time ranges from 30 ms to roughly 1 or 5 seconds. The device includes cable break detection for a 4 to 20 mA current input, circuit damage prevention from reverse polarity, short-circuit protection, and cable break detection for solenoid conductors. Its 16-pole terminal strip connection is housed in a Eurocard printed circuit board measuring 100mm by 160mm, compliant with DIN 41494. Under operation, the unit uses a maximum power of 50 VA and a current consumption of up to 1.8A, within a permissible ambient temperature range of 0°C to +50°C.
