Technical data
The unit switches four independent electrical
loads (alternating current or three-phase
current) by means of one switching contact
each and is particularly suitable for the
switching of loads with a high inrush making
current, e.g.: with compensation capacitors
connected in parallel. Bus connection is
realized via the bus connection terminal on
the front side.
Messages from the bus are routed to the
outputs depending on the selected appli-
cation software and on the parameter setting.
The outputs switch in accordance with a set
preferred state in the event of a bus failure.
