Product Description:
The 075668-402-7 is a Board developed by Bosch for integration in advanced motion control assemblies. The board supports precision performance in systems that require stable power delivery and signal conversion. Bosch has designed the module with a focus on controlled energy handling and consistent electronic regulation.
The 075668-402-7 board has a number of 47µF electrolytic capacitors with a 50V rating. Additionally, it has WIMA film capacitors with markings of 2.2µF and 50V, which are utilized for steady signal conditioning. Both the DC-link and the filtering parts use large power capacitors, which can handle voltages between 400 and 450V. As power transistors or voltage regulators, the TO-220 packages are on the board. There are also operational amplifiers and logic integrated circuits (ICs), such as HP 9927 and LM324 counterparts. As a means of protecting and switching high-power regions, many diodes and MOSFETs are placed in close proximity to one another. In order to regulate the temperature of the voltage regulators, the board has black U-shaped heatsinks. Both the power isolation and signal transmission transformers, with the numbers H0N#V503 and H0N#V507, are part of the package. Without any built-in fans, the board may rely on natural convection. Ribbon cable connectors and IDC-style input/output connectors are available. The design includes X43-1 and X810 screw terminal connectors. DB-style connectors and yellow pin headers connect modular signals.
The 075668-402-7 board includes multiple fused input zones and clearly marked high-voltage insulation spacing for electrical safety. The PCB layout is labeled with versions such as V1.70 and V1.38, which support revision tracking. Extensive test points and silkscreen reference designators are marked for diagnostic access. The board includes grounding zones that maintain system safety and noise reduction. The board is compatible with industrial automation systems that require modular connectivity and reliable control. The integration of heat dissipation components ensures stable performance during continuous duty cycles.
