Product Description:

The VT-MRPA1-151-1X/V0/0 is a pressure-control interface from Bosch Rexroth Indramat in the VT-SWMA Modules series. It converts low-level electrical commands into proportional current for a matched hydraulic valve, allowing a PLC to regulate line pressure without manual adjustment at the valve. By combining signal conditioning and driver electronics in one housing, the unit occupies little cabinet space and provides a direct interface between electronic control hardware and hydraulic actuation. This arrangement helps maintain stable pressure response in automated hydraulic circuits that need repeatable control.

For valve compatibility, the module is calibrated for 2FRE10-4X / 2FRE16-4X pilot-operated pressure valves, which helps preserve a linear relationship between the command signal and hydraulic output. Control power is supplied from a stabilized 24 VDC source, so the unit can operate from common machine-level power rails. The coil drive circuitry controls 1 solenoid, which keeps the output path limited to a single valve channel. Closed-loop regulation is supported by integrated position feedback, which returns actual spool travel to the electronics for correction. Field wiring terminates on screw terminals, a connection method that holds conductors securely in vibrating industrial environments and accepts common ferruled wire ends.

The housing mounts on standardized DIN rails, so it can be installed on 35 mm carrier sections without separate mounting screws. With a mass of 0.23 kg, the unit adds very little load to the rail and supports dense panel layouts. The compact package uses a self-contained Module design that keeps the driver electronics close to the valve connection and helps reduce electrical interference on longer wiring runs. Its narrow format also allows orderly placement beside other hydraulic control components in a cabinet.
