• I/O cards A11 and A12
Most smaller machines have only one card: A11. On some machines,
there is a greater need for outputs, in which case two I/O cards are
used.
The I/O cards are controlled by the CPU card via a serial interface. The
I/O cards feature outputs, which, via the communication cards in the rear
electric box, control various machine functions, such as the water
valves, heater connection and drain valve. On the input connection
blocks of the communication cards, it is possible to connect signals for
control of e.g. the detergent supply.
The cards also have inputs for emergency stop and door lock ACK.
