The relayCUE-8 is an eight-channel relay switching unit for loads up to
10 A per channel. The unit can be controlled by serial channel RS-485
and by potential free contact inputs. These contact inputs are intended to
be used mainly as “wall switches” for direct control of dedicated relay
circuits. To fulfil various tasks, the input operation can be assigned to
different functions by setting their functional parameters in the project
configuration. The programmable parameters are response on the input,
delayed on / off, pulse, and drapes and motor control sequence. Basic
parameters can be set using buttons on front panel, other parameters
are set by serial channel. Front panel includes LED indicators for power
supply, serial channel activity and status of all power relays. The unit can
be combined with all Power Express units. The enclosure allows simple
installation on a DIN rail.

The relay contacts are constructed for resistive load up to
230 V / 10 A. If these relays are used for the switching of inductive or
capacitive loads, voltage or power peaks can occur, which may exceed
these parameters even if the load has the stated take-off lower than
230 V / 10 A. We therefore do not recommend using relayCUE-8 for
switching inductive or capacitive loads with take-off higher than 400 W.
If you need to switch higher inductive or capacitive loads, use contactors.
Unlike relays, contactors are designed with features to control and
suppress the arc produced when interrupting inductive load currents. You
can then use the relay of the unit to control the coil of this contactor.
