60 Control unit

Default I/O diagram of the brake control unit

The diagram below shows the default I/O connections on the brake control unit, and describes
the use of the signals/connections.See also example circuit diagrams.
The wire size accepted by all screw terminals (for both stranded and solid wire) is 0.5 ...
