The VT-VSPA1-537-10/V0/QV-RTP from Bosch Rexroth Indramat features a supply voltage tolerance of +40%/-20% and consumes less than 2 A. Part of the VT-VSPA Proportional Amplifiers, it operates at Operating Voltage 18 to 35 V and limits Power Consumption less than 50 VA. It accepts analog inputs of ±10 V with >100 kΩ impedance and supports 4–20 mA current loops with 100 Ω load.
The adjustable Ramp Time Range 20 ms to 50 s ensures precise acceleration control and zero compensation of ±30% is provided by a Zw potentiometer. Digital inputs switch ON at ≥8.5 V and OFF at 0–6.5 V. An amplitude attenuator range of 0–110% allows fine signal adjustment.
