The Bosch Rexroth Indramat VT 15020-1X/HNC-CPU-Einschub from the VT 1600 Servo Amplifiers series is a robust amplifier card conforming to the DIN 41 494 Eurocard standard with dimensions of 100 x 160 mm, a 128 mm (3U) front panel height and 8 HP width. It draws less than 200 mA supply current and accommodates ±15 V regulated outputs (pins 12ac/22ac). Supply voltage is ±15 V without regulators or ±22 to ±28 V with regulators. The card supports a control voltage range of 0 to ±10 V and model-dependent output currents of ±60 mA or ±100 mA. An integrated dither current of 3 mApp at 340 Hz enhances valve response. Relay coil specifications are 22-28 V, 1 ms duty and 2000 Ω resistance. Rated for storage temperatures from -20 to 70 °C and weighing 0.15 kg, it is designed for reliable industrial automation integration.
