SCU print

The Starter Control Unit is a microprocessor controlled system provided with digital and analog I/O functions
and a serial bus for communication with DeviceNet.
The hardware is distributed over two prints:
• Main board
• Interface board
In order to comply with the EMC requirements (IEC 1000-4), the main board is designed as a 4 layer multi-layer
(Printed Circuit Boards). All inputs and outputs are adequately high-frequency decoupled against interference
signals. A combination of SMD components and conventional components is used for the main board.
The interface board includes varistors for the DeviceNet buses.
