It is suitable for switching electrical components, such as The outputs can be switched by means of standard objects motors, contactors, lamps, louvers, etc. via a BACnet client. The module is addressed and the bitrate is set by means of two address switches on the front. With strong inductive loads, we recommend protecting the relay contacts additionally with an RC element. Suitable for decentralized mounting on DIN TH35 rail according to IEC 60715 in electrical distribution cabinets.
