VT-VRRA1-537-20/V0
VT-VRPA Electric Amplifiers
The VT-VRRA1-537-20/V0, from Bosch Rexroth Indramat, belongs to the VT-VRPA Electric Amplifiers series. This electric amplifier employs a PID with short actuation time dynamic behavior for rapid, precise control in position monitoring applications. A nominal 24V DC supply (2140V range) drives the unit, while onboard diagnostics manage status and safety in real time. Compact and robust, it weighs just Approx. 0.39 kg and occupies minimal panel space, making it ideal for space-constrained automation setups.
Engineered for demanding industrial environments, the amplifier meets IP 66 protection standards and runs continuously at 100% cyclic duration factor without derating. It draws just 55W of power while delivering a maximum solenoid current of 3.7 A and an output signal span of 0…±10 V. Signal-source compatibility includes a Potentiometer 10 kΩ or external transducer, and the unit supports inflected flow with its Linearization Feature. Precise control is maintained with a hysteresis tolerance of ±0.2% and an adjustable zero-point setting of ±15% for on-the-fly calibration.
Integration is streamlined by a standardized DIN 41612 F32 connector type and a shielded position-transducer input that minimizes electrical interference. Short-circuit-proof outputs and automated cable-break detection enhance reliability, quickly isolating faults to prevent system downtime. Broad ambient operation from 0°C to 70°C and a rugged enclosure ensure stable performance in harsh industrial automation applications, from valve control to proportional actuation in process plants.
