Product Description:
The VT-VPCD-1-16/V0/1-P-1 belongs to the VT-VPCD Drives series manufactured by Bosch Rexroth Indramat. It is a DIN-rail control module that links hydraulic or electro-proportional valves to a PLC network and supplies precisely scaled command signals for closed-loop motion or pressure regulation in automated machinery. Within an installation, it converts fieldbus messages into the analog voltages and currents required by the valve, allowing the master controller to set target positions or flow rates without separate analog wiring. This arrangement centralizes valve commands and operating data on the industrial communication network while retaining the analog interface required by the connected actuator.
The unit operates from a nominal supply of 24 VDC, with functional limits between 21 V and 30 V, and draws a steady 3.5 A during normal operation. Its galvanically isolated output stage refreshes every 2 ms, supporting motion sequences that require cycle times shorter than a standard PLC scan. Programmable analog channels deliver ±10 V with a granularity of 10 mV, providing 2,000 command increments across the full 20 V span. A single-node connection to PROFIBUS DPV0 exchanges setpoints and diagnostic data with the central controller. An internal 30 mA reference is available for current-controlled actuators. Hardware supervision monitors the lower and upper supply thresholds so that undervoltage or overvoltage conditions can be reported before signal quality deteriorates.
Sensor feedback enters through differential inputs with an impedance of 100 kΩ for voltage transmitters or 100 Ω for current loops. Current-loop signals are digitized in 5 µA steps to capture small variations from pressure transducers. The output driver can supply command signals to loads as low as 1 kΩ without clipping, supporting compatibility with typical valve electronics. Up to 280 m of local bus cabling can be routed between adjacent Rexroth modules, providing flexibility for connections across large control cabinets. The device weighs 0.2 kg, so it places little additional load on DIN rails and panel assemblies. Its compact format also allows installation near related control modules, reducing the length of analog wiring between the controller and valve electronics.
