dormakaba extension module 90 30

With the extension modules existing installations can be extended without the need for cost-intensive wiring. The extension modules can be used when the control unit requires more binary inputs or relay outputs than are available.


Product details

Extension is performed by simply plugging the extension modules into the control unit. This means that the number of inputs at the access point can be increased.
