Product Description:
The VT-MRMA1-1-1X/V0/0 is a rail-mounted proportional amplifier card produced by Bosch Rexroth Indramat for the VT-VSPA Proportional Amplifiers series. The module converts 24-volt control power into conditioned drive signals for proportional hydraulic valves, enabling closed-loop adjustment of flow or pressure from a PLC or machine controller. Its compact housing fits directly onto a standard TH 35-7.5 mounting rail, and the internal electronics are protected to IP20, making the unit suitable for installation inside electrical cabinets in general industrial automation systems.
The supply stage is designed for a nominal input of 24 VDC. Operation remains stable as long as the cabinet bus stays between 21 V and 35 V, so the board tolerates moderate line variations without losing reference accuracy. Internal conversion and solenoid drive circuits draw up to 50 VA under maximum load, a figure that helps with power supply and heat dissipation planning. A mini-blade fuse rated at 1.6 A sits on the input path to isolate the card if an overcurrent develops, preventing damage to upstream wiring. Four-by-four screw terminals simplify field connections for command, feedback, and power conductors, while a dedicated 10 V sensor rail and a 16 V ready output provide auxiliary voltages to external transducers and status lamps.
During operation, the solenoid output channel can deliver up to 1 A of actuating current for proportional valve coils, while idle consumption is limited to 120 mA, which minimizes continuous thermal loading on the control cabinet. A brief startup surge of 3.5 A is expected while the capacitors charge, so this demand should be considered when selecting circuit breakers. The output monitor path accepts feedback loads up to 50 mA. The entire device weighs only 0.15 kg, reducing the load on the mounting rail and helping accommodate the card inside densely packed enclosures.
