VT2000S/K-30

The VT2000S/K-30 proportional amplifier from Bosch Rexroth Indramat is part of the VT 2000 Proportional Amplifiers series, delivering precise and energy-efficient control for industrial automation systems. This amplifier operates at a nominal operating voltage of 24 VDC (+40%/-5%) with a permissible range of 22–35 V, while consuming less than 1 A of current and under 25 VA of power. Weighing only 0.1 kg, the compact unit measures 100 × 160 mm (Euro-card, DIN 41494) and fits a 3 HE (128.4 mm) front panel height by 4 TE (20.32 mm) width. A robust 32-pin male connector (DIN 41612 form D) ensures secure and standardized connections across diverse control architectures.

Featuring a versatile differential input voltage capability of 0–10 V with 100 kΩ input resistance alongside a command input voltage range of 0–9 V (ref. M0), the VT2000S/K-30 adapts to multiple control devices. Its output current range spans 0–800 mA at a 1 mV/mA ratio for fine-grained actuator control, complemented by a biasing current adjustment of 10–300 mA via potentiometer R130. Selectable clock frequencies of 100 or 200 Hz (±10%) through jumper S2 provide optimal response timing. The amplifier is safeguarded by a 2.5 A slow-blow fuse, preventing overcurrent events while maintaining uptime.

Operational flexibility is enhanced by an adjustable ramp time from 30 ms up to 1 or 5 s (jumper S1), allowing seamless acceleration profiles that reduce mechanical stress. The durable assembly withstands a permissible operating temperature of 0–50 °C, ensuring reliable performance in varied environments. With a slim form factor and Euro-card dimensions, integration into rack-mounted systems is straightforward, while the low weight minimizes installation effort. The low power draw and efficient thermal characteristics support energy-saving initiatives without compromising output stability.

Designed for seamless system integration, the VT2000S/K-30’s 32-pin male connector (DIN 41612) simplifies cabling in dense control cabinets. Its standard Euro-card format and front panel layout facilitate interoperability with existing racks and modules. Backed by a 1 year warranty, this amplifier is ideal for proportional valve control, motion systems, and precise pressure regulation across hydraulic and pneumatic applications. Bosch Rexroth Indramat’s proven reliability and the VT 2000 Proportional Amplifiers series deliver a versatile solution for advanced industrial automation challenges.
