Product Description:

The Bosch Rexroth Indramat VT-MRPA1-2-10/V0/0, which is a part of the VT-VSPA Proportional Amplifiers line, offers precise control capabilities for automated factories.

To accommodate various power source types, this control system operates with a 24 VDC power supply within the 20% to 40% tolerance zone. The safe operating voltage range for this control system is 18 V to 35 V. This gadget operates as energy-efficiently as possible while using 50 VA or less of power and less than 2 A of current. A 2A fuse with a medium slow rating guards against overcurrent. Using M0 as the reference, the command value inputs (1–4) handle voltage signals between 0 and 10 V with impedances greater than 100 kΩ. For many control systems, the command input value 5 has an input resistance of more than 50 kΩ and operates with analog signals ranging from 0 to +10 volts. With a 100-ohm load resistance and 4 to 20 mA signals, the current input precisely measures values. The external ramp time function handles voltage signals from 0 to 10 volts, which are then boosted to 15 volts, using a 10 kΩ input.

For best results, you can select input levels between -30% and +30% using the zero-compensation range (zw). Users can adjust control parameters from 0% to 110% to suit their needs using the command values w1 through w4. Users may change the ramp time control from 20 ms to 5 seconds, however, for specific acceleration and deceleration speed management, they can utilize a range of 0.2 to 50 s. To customize the equipment used, the amplitude attenuation ranges from 0% to 110% and the step level control ranges from 0% to 50%. With dimensions of 100 by 160 mm and a weight of 0.17 kg, the VT-MRPA1-2-10/V0/0 complies with DIN 41494 requirements to function flawlessly with industrial systems.
