VT-MRPA2-2-1X/V0/0

The VT-MRPA2-2-1X/V0/0 is a rail-mounted electronics unit produced by Bosch Rexroth Indramat within the VT-SWMA Modules series. It acts as a control interface between a PLC and hydraulic proportional directional valves, translating low-level command signals into drive currents while monitoring spool position. By integrating valve actuation and feedback in a single housing, the module simplifies installation in industrial automation systems that demand precise flow direction and repeatable cylinder positioning on assembly lines or press equipment.

Electrical power is derived from a stabilized 24 VDC bus, so the module can share a common control supply with sensors and relays already present in most machinery cabinets. Internally, it allocates current to two independent solenoid drivers, enabling simultaneous control of both sides of a bidirectional spool. The output stage is tuned for proportional directional valves, and its characteristic curve matches the magnet requirements of the Bosch Rexroth 4WRE 10-2X family. This compatibility eliminates the need for manual gain trimming. Maintenance access is simplified because the enclosure clips onto a DIN rail, supporting tool-free removal in crowded panels.

Field wiring enters through screw terminals, providing secure, vibration-resistant connections that can be retightened with a standard flat-blade screwdriver. A built-in circuit processes position feedback, enabling closed-loop spool centering without auxiliary cards and improving repeatability during small-signal movements. At only 0.22 kg, the housing adds minimal mass to light-duty racks and can be mounted adjacent to other cards without extra support. The overall arrangement uses a compact module format, so multiple units can be installed together to expand the channel count while keeping cabinet depth within the limits of typical industrial enclosures.
