Product Description:
Bosch Rexroth Indramat manufactures the VT1600S31 1, a plug-in servo amplifier card in the VT 1600 Servo Amplifiers series. The board uses the 3U Eurocard format, weighs 0.15 kg, and fits into system racks where it conditions command signals for proportional or servo-controlled actuators on production equipment. By providing regulated current drive, the card links the machine controller to field devices and supports closed-loop positioning and force regulation. This type of module is used where stable current control is required for accurate actuator response in hydraulic or electrohydraulic systems. Its compact format helps conserve cabinet space while still allowing integration into modular rack-based control systems.
The card operates from a nominal bus of ±24 V and accepts differential control inputs up to ±10 V. Internal circuitry draws less than 200 mA, so several amplifier cards can share the same low-capacity supply without placing a heavy load on it. The output stages have a coil resistance of 2000 Ω, which suits common pilot valves, and the DIN 41612 backplane connector provides 32 signal and power pins. The differential input arrangement also helps reduce the effect of electrical noise that may be present on command wiring inside a control cabinet. A fixed dither of 340 Hz with a 3 mAPP amplitude reduces stiction in hydraulic spools, and the 1 ms duty cycle keeps the modulation fast and consistent during valve control.
The board footprint is 100 × 160 mm, and the front bezel spans 8 HP, which leaves room for labeling and test-point access on the rack front. Continuous operation is intended between 0 °C and 50 °C, while stored equipment can tolerate -20 °C to 70 °C without damage to normal operating function. The mechanical format matches standard sub-racks, which supports straightforward installation in compatible rack systems. That layout keeps the card aligned with neighboring modules and preserves access to the rack backplane connections. The specified clearances also support organized airflow around neighboring modules in cabinets that use forced-air cooling.
