Bosch Rexroth 1M45-0.8A Amplifier Card

Bosch Rexroth Indramat 1M45-0.8A Amplifier Card is a plug‑in part of the 1M servo amplifier family that drives coil actuators in hydraulic and motion‑control systems. This variant provides an 0.8 A (20 VA) solenoid output suitable for smaller valve coils, with other 1M cards offering higher ratings such as 2.5 A (25 W) depending on the exact model. The amplifier card is designed to integrate with Rexroth/Indramat control architectures to translate control signals into precise valve actuation, enabling repeatable valve response and controlled hydraulic or pneumatic actuation in automated machinery. For installation and commissioning, confirm the exact variant number to ensure the correct output capability and electrical interfaces, as the 1M family includes multiple configurations. Typical use cases include proportional valve control and servo valve actuation in compact motion systems, where reliable on/off or modulated coil drive is required. When selecting a unit, verify the rated current (0.8 A) and coil power (20 VA) for compatibility with your valve or actuator, and check that the card’s form factor and connector layout match your enclosure and backplane. The 1M45‑0.8A card is part of Bosch Rexroth Indramat’s legacy line of modular amplifier cards, known for rugged industrial performance in demanding environments.
