Product Description:

The VT-VRPA1-527-10/V0/QV-RTP is a constructive module of Amplifier Card by Rexroth for precise control of hydraulic directional spool valves. Rexroth has set an impressive standard in the world of industrial automation. Their dedication to quality truly stands out by making them a trusted partner for companies around the globe.

This VT-VRPA1-527-10/V0/QV-RTP amplifier card consists of position feedback at the analog side using a potentiometer that operates from 0 to 10 V. This helps in ensuring accurate valve positioning and reliable operation in industrial applications. This module operates with a signal range of 0 to 10 V which helps in making it compatible with standards. The amplifier card provides highly sturdy iron housing that enhances its longevity. The VT-VRPA series amplifier card is IP65-rated by providing protection against dust and water droplets. It has a higher shock resistance of 15 g per 6 ms and vibration resistance of 5 g that lies between a frequency of 10-500 Hz by ensuring stable performance. This module functions at a high operating pressure that is up to 315 bar by supporting a high flow rate at 60 L per min by enabling efficient fluid control.

This VT-VRPA1-527-10/V0/QV-RTP amplifier card needs a supply voltage of 24 volts at DC and is designed for subplate mounting. The module is capable of providing connections at screw terminals type. It meets CE and UL approvals by demonstrating international safety. This amplifier is an essential component for precise valve control in hydraulic machinery. It requires a specified temperature operation that ranges from -20 to +50 °C and can tolerate 90% humidity with low moisture without disturbing its overall working.
