Product Description:
The VT 3000 S 30 is an analog amplifier card produced by Bosch Rexroth Indramat and belongs to the VT 3000 Analog Amplifiers series. The Eurocard-format module plugs into a 32-pin DIN backplane and provides closed-loop current control for proportional solenoid valves in industrial hydraulic drives. Within an automation rack, it converts set-point voltages from a PLC into precisely metered coil currents, allowing directional, pressure, or flow valves to respond linearly to electronic commands and helping stabilize motion or process variables across repeated machine cycles.
It operates from a stabilized supply of 24 VDC ±10%, and the internal circuitry can draw up to 30 W during maximum dynamic response. Control inputs span ±9 V, and the differential design minimizes common-mode noise picked up over field wiring. Primary overcurrent protection is provided by a 2.5 A time-lag fuse housed in a 5 × 20 mm glass cartridge, which is accessible from the front panel. In the cabinet, the card occupies eight faceplate grid divisions, seven component-side divisions, and one conductor-side division, which follows the Eurocard slot-spacing standard and preserves clearance for neighboring modules.
The power stage can source up to 800 mA of regulated current, enabling direct drive of pilot coils whose cold resistance is no higher than 19.5 Ω. A fixed bias of 20 mA reduces valve hysteresis when the command signal is near zero. The input section accepts commands only from sources presenting 500 Ω or greater, which helps protect low-power transmitters. Temperature stability is characterized by a drift of 0.5 ‰/K, so gain changes remain negligible over normal cabinet temperature swings. The compact Eurocard layout helps maintain orderly rack installation and leaves room for adjacent modules during dense control-cabinet assembly.
