Operation
71 Relay assignment
5-28
In the basic unit, six programmable relays are available. Their reversible
output contacts (max. 24 V / 1 A) can be used for signaling, controlling
valves, and so on.
Should these six relays be insufficient it is possible to obtain a further
eight relays by installing an additional electronics module (option).
One of the functions listed in Table 5.4 can be assigned to each relay but
each function may only be assigned once. What this means is that a fault
signal, for example, cannot be sent to two relays.
Pin assignments for the individual relays in the non-energized state can
be seen in the assignments diagram "Electrical connections" on page 3-5.
The unit is shipped with the relays preset.
Up to four inputs can be configured in a menu screen. Switching to further
menu screens – and thus to more binary inputs – is always done by
pressing the fifth soft key ("...more").
