Product Description:
The VT-1600S3X-E servo amplifier card is produced by Bosch Rexroth Indramat within the VT 1600 Servo Amplifiers series. It is designed to regulate the current applied to proportional solenoid coils, allowing closed-loop control of hydraulic valve positions in industrial automation systems. Mounted in a Eurocard rack, the card interfaces between a motion controller and the field actuator, shaping low-level command signals into the precise coil currents required for repeatable valve movement.
It draws a maximum supply current of < 200 mA, so the rack power bus experiences minimal loading even when several cards are installed. The output stage is matched to solenoids presenting a coil resistance near 2000 Ω, which keeps heat dissipation low while still allowing fast magnetic response. To overcome static friction in the hydraulic spool, the onboard oscillator injects a dither signal of 3 mAPP at a carrier frequency of 340 Hz; this superimposed ripple widens the control resolution without causing audible noise. The amplifier’s logic synchronizes pulse generation on a 1 ms duty-cycle window, ensuring consistent averaging of the modulated current. Physically, the card occupies a standard Eurocard footprint measuring 100 x 160 mm, enabling direct insertion into DIN 41612 back-plane connectors without additional adapters.
The mechanical outline supports orderly panel layout. Its aluminum front plate rises to 128 mm and spans 8 HP, giving adequate space for diagnostic LEDs and the zero-adjust potentiometer. Behind the plate, component placement is limited to seven grid divisions on the component side, while the solder side maintains a clearance width of 5.08 mm to simplify airflow between adjacent cards. Reliable operation is specified for ambient temperatures from 0–50 °C; when the machine is idle, the module tolerates storage conditions between –20 and 70 °C without performance drift.
