Relay expansion A00.12 consists of master and slave Relay modules, both of which have 8 relay outputs. The master is connected to the Relay card RS232-1 bus, and the slave is connected to the Master with a connecting cable. A key can simultaneously control 1-16 relay outputs of the Relay module.

The available relay modes are:

  • Toggle
  • Impulse
  • Key hold

In the impulse mode, the default length of the Relay module impulse is 8 seconds.

In this configuration, it is possible to specify the relay outputs that a particular access right has the right to control. A valid key can, therefore, activate 1-16 relays of the Relay module. In addition, a valid key always activates both relay outputs K1 and K2 of the Relay card.

When the relay mode is impulse, and if a valid key is read in the Key reader, while the previous impulse is still active, the Relay module’s relays will be set according to the relay combination of the last valid key. In other words if, for example, relay output 3 has been activated by key 1 when the control is still on, key 2, which only controls, for example, relays 4 and 5, will be read. In this case, relay 3 will stop activating, whereupon only the relay combination of the last key, that is, 4 and 5, will be activated.

The Relay card 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. The Relay module relays cannot be controlled with button input Button1.
