The terminal expansion board CUD2 is mounted on the basic electronics assembly CUD1 and does not require any additional built-in components. This board provides a range of additional inputs and outputs.

Apart from these additional inputs and outputs, terminal expansion board CUD2 provides an additional RS 485 serial interface as well as a parallel interface for connecting up to 5 power supply modules in parallel.
