Universal input and output module for building control. The device offers 48 digital channels. Each channel can be used as a binary input, binary output or as a blind output. Input channels can be used to connect buttons. Output channels can directly control signal LEDs, external coupling relays or blind relays. The periphery (e.g., relay) is powered by an external power supply (24V).

Universal input and output module for KNX IP. The device offers 48 digital channels. Each channel can be used as a binary input, binary output or as a blind output. Input channels can be used to connect buttons. Output channels can directly control signal LEDs, external coupling relays or blind relays. The periphery (e.g., relay) is powered by an external power supply (24V). The device operates using the medium KNX IP and is connected via LAN / Ethernet to the KNX installation.

Relay extension / coupling relay with reduced holding current. The relay extension serves as a power-saving alternative for commercially available coupling relays. Bistable relay internal, external control like monostable relay.

Double relay especially for the control of blinds and shutters. The double relay is connected to only one output of a KNX Multi IO. Direction control of the relay outputs takes place by means of an encoding of the input voltage.
