VT-MRPA1-100-11/V0/0
The Bosch Rexroth Indramat VT-MRPA1-100-11/V0/0 proportional amplifier from the VT-VSPA Proportional Amplifiers series operates with an 8.5 V operating voltage and delivers a response voltage of 16.8 V, driving coils with 2150 Ω coil resistance. Housed on a 100 x 160 mm European format card with a 32-pin DIN 41612 Design D plug, it supports a clock frequency of 1.5 kHz and an oscillator frequency of 2.5 kHz ±10%. The module allows ±9 V adjustment voltage, output currents up to 1.8 A ±20% through 5.4 Ω resistance, and incorporates short-circuit safety. Rated for 0–50 °C operation (−25–85 °C storage), it enables fine-tuning of zero-point command and ramp times via integrated potentiometers, ensuring precise PID closed-loop control for industrial automation.
