Art.-No.: KIO3 • Techn. Drawing: Power-Adapter KIO3


The Kentix I/O Power-Adapter KIO3 is used to extend your Kentix solution with the following functions:

  • Connection of up to two external alarms via potential-free contacts for a MultiSensor
  • Control or switching of up to 2 external devices via relay from one MultiSensor

The adapter is connected directly to the Kentix system socket (1). The power supply for the relays is generated via the system socket and does not require an external power source. The cable length between MultiSensor and KIO3 adapter should not exceed 10 meters. The relays (3) are equipped with changeover contacts and can be loaded with up to 60VDC/3A.

KIO3 Connections

External devices, which are triggered via the relays of the KIO3 at an assigned event, have to be supplied with power independently! E.g. if a lamp is to be switched in case of an alarm, the power supply to the lamp must be guaranteed. The relay only opens or closes the circuit at the respective event!


  1. Kentix system socket for connection to device system socket of e.g. AlarmManager, MultiSensor-LAN or AccessManager. (system port1)
  2. Kentix system socket for connection to device system socket of e.g., AlarmManager, MultiSensor-LAN or AccessManager. (system port2)

Circuit diagram with external alarms


On all Kentix devices, the digital inputs must always be connected potential-free. This means that no external voltage must be applied. The wiring is typically done passively by normally closed or normally open contacts without voltage potential. The contact logic can be freely set in the software. The application of an external voltage can lead to a device defect.
