R901439036
The Bosch Rexroth Indramat's R901439036 (VT-MSPA1-2X-F5-000-000) is a valve amplifier developed for proportional valves and pump controls, lacking electrical position feedback. Belonging to the 2X components series, the amplifier possesses adjustable valve parameters with a command value current range of 40 to 20 milliamps. The stored characteristic curves can be optimized through push buttons. Assembly is designed for top hat rails, and the electrical connection is via three tension spring plug-in connectors. The acceptable supply voltage ranges from 18 to 36 Volts DC, with a regular operational voltage of 24 volts DC. The amplifier limits current peaks with its making current limiter and protects against inverse polarity.
R901439036 (VT-MSPA1-2X-F5-000-000)'s maximum power and current draw do not exceed 48 Watts and 2 Amps respectively, with the switch-on current capped at 4 Amps. It includes a delay fuse rated at 3.5 Amps, powers up in under a second, and is classified as IP20 protection as per EN 60529. Optimum operation is within 0 to 60 degrees Celsius, and storage in -40 to 70 degrees Celsius, or with UV protection, between 5 to 40 degrees Celsius. Note that the part UV-resistant housing may discolor with prolonged radiation exposure. The amplifier should be installed vertically and measures 99 x 22.5 x 114 millimeters.
