Technical data – Bus Coupler housing

The Beckhoff Bus Coupler electronics can be mounted in a variety of housings. A housing has 3 power contacts, which, if the application requires, automatically implement a continued connection, carrying the potential of the power circuit to the next Bus Terminal. The supply voltage that is connected to the Bus Coupler spring-loaded terminals is 24 V DC. If a different voltage is required for the power contacts, the appropriate power feed terminal must be inserted after the Bus Coupler.
