The Bosch Rexroth Indramat VT 3013-37 analog amplifier, part of the VT 3000 Analog Amplifiers series, delivers robust signal processing capabilities for demanding industrial automation environments. Designed for precision control applications, it operates with a 24 VDC ±10% power supply voltage and supports a pulse frequency range of 160 to 180 Hz to accommodate rapid command-response cycles. Its compact form factor and a weight of 0.33 lb (0.15 kg) make it an ideal solution for installations with stringent space and weight constraints. The amplifier’s differential analog input capability accepts 0–10 V difference between pins 16a and 16c, ensuring high signal fidelity while rejecting common-mode noise. Integrated protection and reliability features provide uninterrupted performance under continuous operation.
In-depth technical specifications define the VT 3013-37’s operational envelope. It requires a power requirement of 30 W to maintain its output stages, while a 2.5 Ampere fuse rating (5 mm x 20 mm) safeguards against overcurrent events. The input control voltage of ±9 V allows for compatibility with a variety of control sources, and its minimum input load of ≥ 500 Ω prevents undue loading of the drive circuitry. For output stages, the device delivers up to 800 mA maximum output current into loads not exceeding 19.5 Ω coil resistance and maintains a minimum output (bias) current of 20 mA to ensure proper coil excitation. Space allocation within control cabinets is streamlined by the 0.200 in (5.08 mm) per TE (1 HP) space requirement, facilitating dense panel layouts.
Operational performance emphasizes accuracy and stability in industrial applications. Test points BU2 and BU3 provide real-time measurement of output signals ranging from 20 mA to 800 mA, enabling precise diagnostics and tuning during commissioning. The amplifier’s temperature drift of 0.5% per K (from Imax) ensures consistent current delivery over the specified ambient range, minimizing performance variation. The differential analog input system not only enhances signal precision but also rejects common-mode interference, resulting in dependable control outputs. With a robust fuse rating and comprehensive overload protection, the VT 3013-37 maintains continuous operation even in harsh electrical environments.
System integration is streamlined by the VT 3013-37’s compatibility with standard industrial automation frameworks and its compact footprint of 1 division = 0.200 inches (5.08 mm) per TE (1 HP). The amplifier’s design supports seamless retrofitting into existing Bosch Rexroth Indramat control cabinets, reducing engineering effort during upgrades. Target applications include servo valve control, proportional valve drivers, and precision motion control in packaging, metalworking, and mobile hydraulics systems. As a member of the VT 3000 Analog Amplifiers series, the VT 3013-37 offers proven reliability and consistent performance for modern industrial automation solutions.
