The Bosch Rexroth VT-VSPA1K-1-1X/ SO43A-1668 (R978914789) is a sophisticated control card designed for precision management of proportional valves. This card belongs to the component series X and comes in an analog, Eurocard format, making it compatible with a range of valve types including DBEP AB ...X, DBEM ...X, DBEM ...X, DBEM ...X, ZDBE ...X, DREM ...X, DREM ...X, DREM ...X, and ZDRE VP ...X. This model features a ramp generator that can create a ramp-shaped output signal from stepped input signals. The time constants for this ramp signal can be adjusted separately for both upward and downward directions to achieve the desired response rate. The ramp generator's characteristics can be further modified through external Ramp Up/Down off contacts in type VT-VSPA or via an external Ramp off contact in type VTVSPAK. The VT-VSPA1K-1-1X/ SO43A-1668 provides multiple command value inputs: a differential input which can be switched between voltage and current modes, as well as an additional non-isolated command value input. Cable break detection is included for the current input ranging from 0 to 20 mA. Safety features are built into this control card with reverse polarity protection for the operating voltage and short-circuit protection along with cable break detection of the solenoid conductor. It also includes a clocked power output stage that ensures smooth operation of connected valves. The unit has ready-for-operation messaging which is indicated by an LED light on its front plate when there are no faults detected such as short circuits or cable breaks. In case of any discrepancies in operation or connection errors, this system provides clear diagnostic feedback through its various indicators. Overall, the Bosch Rexroth VT-VSPA1K-1-1X/ SO43A-1668 offers precise control and safety features making it an essential component for hydraulic systems requiring accurate valve actuation and monitoring.
