VT 3000 S 32
The Bosch Rexroth Indramat VT 3000 S 32 proportional valve amplifier is a robust electronic control module designed for precision hydraulic applications. As part of the renowned VT 3000 Analog Amplifiers series, this amplifier (part_number: VT 3000 S 32; manufacturer: Bosch Rexroth Indramat) delivers a nominal Operating Voltage: 24 VDC ±10% and features a Connection Type: 32 pin plug-in Euro card design for streamlined integration into modular control racks. Constructed in a compact Euro card format, the Product: VT 3000 platform ensures consistent performance when paired with Model 4 WRZ proportional directional valves (sizes 10–52). Built-in voltage stabilization maintains a constant supply level under fluctuating input conditions, while the factory-assigned Ramp Time generators provide smooth control over acceleration and deceleration phases. The amplifier’s layout supports a 10 Volt differential amplifier input for direct interfacing with programmable logic controllers, computers, and microprocessors without additional signal conditioning.
Designed for demanding industrial environments, the VT 3000 S 32 incorporates a precision voltage stabilizer that compensates for supply variations and a configurable ramp generator with selectable 1 s or 5 s time constants to manage actuator movement profiles. A dedicated function generator actively eliminates valve deadband, enabling instantaneous reversal and minimizing hysteresis in high-speed positioning tasks. Front-panel diagnostics include four LED indicators that provide real-time status of input relays and fault conditions, simplifying troubleshooting and reducing downtime. The amplifier accepts an input control voltage: ±9 VDC and consumes Power Consumption: 30 W under nominal conditions, ensuring energy-efficient operation. Its plug-and-play design streamlines maintenance procedures, and the modular card architecture minimizes replacement time to maintain continuous production uptime.
Reliability is further enhanced by a wide operating range of Working Temperature: 0 to 50 °C (32 to 122 °F) and a lightweight construction weighing approximately Weight: 0.15 kg, facilitating installation in space-constrained control cabinets. The VT 3000 S 32 requires de-energized connections—operators must power off before plugging or unplugging cards—and the use of high-impedance meters when performing measurements to ensure safe handling. Proximity to radio transceivers or radar equipment is discouraged to prevent electromagnetic interference that could affect valve control accuracy. In case of instability, technicians are advised to bleed air from the solenoids with the electronics deactivated, following Bosch safety guidelines. Intended for integration with Rexroth’s range of proportional directional valves, this amplifier excels in mobile and stationary hydraulics, material handling, and automated manufacturing systems where precise flow and pressure control are critical.
