The Bosch Rexroth Indramat VT-VRPA2-1-10a/V0/T1 from the VT-VRPA Electric Amplifiers series by Bosch Rexroth Indramat is an industrial-grade electrical valve amplifier designed to deliver precise proportional control for directional valves. It operates on a 24 VDC supply voltage with an operating range of 18–35 VDC, consuming less than 24 VA and under 2 A of current, protected by a 2 A fuse. Inputs include analog potentiometer, differential and current channels with a range of ±10 V to ±20 mA and digital inputs at 6.5–8.5 V, while outputs provide command, actual value and measurement signals with ±2 % accuracy at up to 2 mA. The amplifier features short-circuit-proof power output stages and an integrated 5.6 kHz oscillator, offering adjustable zero point, ramp times and amplitude attenuation for optimized hydraulic system performance.
