With the Relay card, you can control one or two devices through the relay outputs K1 and K2.
The available relay modes are:
- Key hold
- Roller door
In this configuration, a valid key always activates both relay outputs K1 and K2, except in the roller door mode, which is a special connection (see Roller Door). Relay outputs can also be activated with a potential-free contact signal (for example, a push button) to input Button1. In this case, relays K1 and K2 will behave according to the selected relay mode in the same way as with a key.
A practical example for the impulse mode with default delay times: a motorised lock is controlled with an 8 second impulse of the K1 relay, and the K2 relay is used to bypass the magnetic switch of the door, for 30 seconds. When exiting the premises, the user presses a push button, whereupon the motorised lock is opened and the door’s magnetic switch is bypassed for 30 seconds.
