Bpt KX4O16A, Manual

Page: 14 / 48

The KNX 4-channel 16 AX actuator with manual control - DIN rail mounting allows
up to 4 different electrical loads to be activated/deactivated separately by means of
4 x 16 AX relays, each one fitted with 1 NO output contact. The relay switchover
command can come from command devices or sensors of the Building Automation
system via the KNX bus or generated locally via the front push-buttons.
The device has an auxiliary 230Vac input that makes it possible to control connected
loads through the front push-buttons also without KNX BUS voltage (with 230Vac
mains voltage present).
The actuator is powered from the BUS line and is equipped with 4 front green LEDs
for signalling the output status. The device sends information to the bus about the
relay status (ON = contact closed, OFF = contact open) when switching on,
receiving a command and in the case of a command from a local push-button.
Each output channel of the actuator can be configured separately and allows the
ON/OFF command of the controlled loads, execution of timed commands, scene
management and execution of priority commands to force the output status. The
functioning modes can be used simultaneously by means of distinct communication
objects.
This means, for instance, that the device can switch a light on and off, or
automatically switch it on and off after a certain pre-established time, simply on
the basis of the command received.
The module is assembled on the DIN rail, inside the electric boards or junction
boxes.
