VT 3015-S-1X/E by Bosch Rexroth Indramat

The Bosch Rexroth Indramat VT 3015-S-1X/E is a high-performance analog amplifier card within the VT 3000 Analog Amplifiers series, designed for demanding industrial automation environments. This Proportional/Drive Control Card supports a 24 VDC input voltage and offers robust galvanic isolation between I/O sections to safeguard sensitive electronics. Housed in a versatile Eurocard or custom mounting style format, the VT 3015-S-1X/E provides a compact footprint requiring only 7 divisions on the component side. With integrated digital/analog I/O interfaces and a dedicated differential input, this amplifier delivers precise control of proportional valves without electrical position feedback.

Technical capabilities of the VT 3015-S-1X/E include a Fieldbus or proprietary REXROTH protocol communication protocol, enabling seamless integration into existing control networks. The unit’s low power consumption design minimizes thermal stress, while the Operating Temperature Range of approximately -10 °C to +55 °C ensures reliable performance across a broad range of conditions. A robust rem anufacturing status of repair/refurbished per manufacturer specifications and clear revision information printed on the PCB facilitate lifecycle management and traceability. The amplifier’s signal interface supports both digital and analog signals, and its polarity protection on the 24 VDC power supply prevents damage from incorrect connections.

Operational features include four adjustable command values, each set via dedicated potentiometers and monitored through a front-panel LED display for immediate status feedback. The preset ramp time of 5 seconds ensures smooth transitions and prevents hydraulic shock during valve actuation. Two pulsed current output stages deliver proportional current to pilot-operated directional or direct-operated pressure valves, while the absence of free wheel diodes on associated solenoids avoids unwanted feedback paths. Screening of solenoid lines is recommended to reduce electromagnetic interference, and the upright-only mounting orientation preserves proper heat dissipation and mechanical stability.

Integration of the VT 3015-S-1X/E is straightforward in applications requiring high-precision hydraulic control, such as machine tools, injection molding presses, and mobile hydraulics. The amplifier mates directly with the VT 3002-2X/32 card holder without a power pack, simplifying cabinet design and reducing wiring complexity. Its reliable galvanic isolation, versatile signal interfaces, and rugged industrial construction make it ideal for demanding fieldbus architectures and proprietary Rexroth control systems. With full compatibility across the VT 3000 series, the VT 3015-S-1X/E enhances system modularity, serviceability, and overall operational efficiency.
