Internal Product Review
The VT 3017-37 is a Bosch Rexroth Indramat analog amplifier that delivers dependable control performance with a 24 VDC ±10% supply and 800 mA max output current. Signal handling is especially capable thanks to 4 × ±9 V command inputs and a 10 V differential input, which supports clean integration in analog control circuits. Low 0.5‰/K temperature drift is a standout advantage for consistent amplifier behavior.

Product Description:
The VT 3017-37 is an analog amplifier card engineered by Bosch Rexroth Indramat for installation in a VT 3000 Analog Amplifiers series rack. Within an automation cabinet, it translates voltage references from a motion controller into regulated coil current. This operation allows proportional hydraulic or pneumatic actuators to follow a commanded position or force profile with predictable dynamics.
The module accepts four command channels, each operating over an input range of ±9 V, so individual axes can be driven from standard ±10 V motion cards without scaling. A differential stage tolerates up to 10 V between its noninverting and inverting inputs, helping preserve signal integrity in the presence of common-mode noise. Connected sources see a minimum load of 500 Ω, which prevents excessive current draw from PLC analog outputs. The power stage can deliver up to 800 mA to field coils and remains linear when the connected load is at least 19.5 Ω. All circuitry is energized from a single control supply of 24 VDC ±10%. This tolerance allows the card to operate from unregulated machine supplies while maintaining output accuracy.
Circuit protection is provided by a panel-mounted fuse rated at 2.5 A, which isolates the card if coil shorts or wiring faults occur. Internal power loss can reach 30 W, a value that can be used when determining enclosure ventilation requirements. For baseline excitation, the driver maintains a minimum bias current of 20 mA. An auxiliary command port accepts override signals up to ±6 V for fine trimming or feed-forward control. The card measures 14 mm wide, 170 mm deep, and 185 mm high, allowing compact installation within the rack. Temperature drift remains limited to 0.5 ‰/K, helping keep zero offsets stable as the cabinet temperature changes. The assembly weighs 0.15 kg, minimizing the mechanical load placed on light-duty card guides.
