Relay

You can configure the switching behavior of the relay output. Relay action can be

specified either as open switch (normally closed contact) or closed switch

(normally open contact).

It is also possible to specify whether the output signal should be bistable or

monostable. With bistable operation, the relay remains in the activated state.

With monostable operation, the delay time can be selected after which the relay

reverts to its idle state.

You can choose various events that activate the output automatically. Thus, for

example, it is possible to switch on a spotlight in response to a motion alarm and

switch it off again when the alarm situation is no longer active.

Idle state:

Select Open if the relay is to operate as a normally open contact or Closed if it

is to operate as a normally closed contact.

Operating mode:

Select an operating mode for the relay.

If, for example, a light switched on by an alarm is to remain lit when the alarm has

ended, select Bistable. If an audible signal activated by an alarm is to sound for

a period of ten seconds for example, select 10 sec.
