Product Description:
The Bosch Rexroth Indramat VT 2000-51 proportional amplifier belongs to the VT 2000 Proportional Amplifiers series. It is a plug-in Eurocard that interfaces between a motion controller and a hydraulic proportional valve, shaping command voltages into controlled solenoid current so that flow, pressure, or cylinder position can be set precisely in industrial automation cells. By occupying a 3U rack slot next to PLC or NC hardware, the card minimizes wiring runs and keeps the power stage inside the protected cabinet.
The board size is 100 × 160 mm, matching IEC 60297 subracks, and its connector is a 32-pin male, DIN 41612 form D plug that mates with backplane power and signal buses. Supply power is taken from a nominal 24 VDC (+40%/-5%) rail, and overall dissipation stays under <25 VA, so forced cooling is normally unnecessary. When a control system outputs the full reference of +6 V = 100%, the amplifier drives the valve to its maximum rated stroke. Diagnostic test points follow a scale of 1 mV = 1 mA, allowing coil current to be read directly with a multimeter. A time-lag 2.5 A fuse protects the card, and the bias network can add up to 300 mA for valve offset trimming.
For dynamic operation, the unit regulates load current within ±25 mA and can supply a peak of 800 mA (+10%/-5%) to fast-acting solenoids that measure 19.5 Ω at 20 °C. Internal reference rails are held at ±9 V (±1%) to keep analog circuitry stable over temperature. Continuous service is rated to 50 °C ambient, letting machines run in typical factory enclosures without extra climate control. Despite these electrical capabilities, the card weighs only 0.1 kg, which reduces mechanical load on the backplane connectors during handling.
