Input/ Output Connector Board (Optional)
The input/ output connector (article no. 02-0128, figure 1) serves as the input for indicator or counting
contacts as well as for the activation of electrical control elements and external systems.
Relay 1 (Figure 2)
Relay 1 is exclusively used for the activation of an electrical access control element.
Switching power of the contacts: 30V 2A
Relays 2 and 3
The relays 2 and 3 are provided for custom-specific applications. Depending on the programming of
the host software, these relays are switched on, off or timed.
Switching power of the contacts: 30V 1A
All of the relays are equipped with floating NO and NC contacts. The adjustment of the desired contact
type is carried out by means of jumpers.
Input Contacts (Figure 3)
Input contacts serve to scan the status of indicating sensors: Two contact inputs can also be used as
counting contacts, if required.
Input Contacts 1 and 2
These two input contacts are exclusively reserved for the connection of door indicator contacts.
Contact Inputs 3 and 4
The input contacts 3 and 4 are provided for custom-specific applications. Depending on the
parameterization, they can be used as counting or indicator/ status contacts.
