9.2.2 Digital outputs
A number of digital outputs are provided, to provide status signals for the customer. Note that
these outputs are electronic, rated at 24V 1A each. For remote signaling, suitable relays will
need to be fitted and their coils wired to the respective digital outputs.
Table 9-2 summarizes these digital outputs.
