Product Description:

The VT 1610-3X/E0/VT8-4366/U150 servo amplifier is produced by Bosch Rexroth Indramat as part of the VT 1600 Servo Amplifiers series. Used inside hydraulic proportional-valve controls, it converts low-level command signals from a PLC or analog source into a conditioned current that actuates the valve spool. By integrating signal conditioning, dither generation, and protective monitoring on a single Eurocard, the VT 1610-3X/E0/VT8-4366/U150 helps maintain stable flow or pressure regulation in industrial automation systems.

Laid out as a compact rack module, the amplifier draws less than 200 mA from the control cabinet power rail, yet it can deliver up to ±60 mA of controlled output current to a valve coil. The output is modulated by an internally generated dither fixed at 340 Hz with an amplitude of 3 mAss; this combination minimizes static friction in directional or pressure valves. Power for the analog stages is supplied by a symmetrical bus of ±22 to 28 V, allowing direct operation from common 24 V control supplies. The card occupies only a 1/7-division slot width, so adjacent modules can be packed tightly in the same sub-rack.

The input stage accepts command references from 0 to ±10 V and routes them through an onboard relay coil, eliminating external switching components. Coil current accuracy is assisted by a 2000 Ω sensing network and a card edge that mates with a DIN 41612 Form D, 32-pole connector. The board follows a 5.08 mm pin pitch and weighs just 0.20 kg, which eases handling during cabinet assembly. A separate ±15 V monitor supply supports onboard electronics, and because there is no voltage regulator on the card, the system power supply must maintain stable rails.
