Local Control Network - building controls in perfection
Sensor technology
The red sensor connecting plugs are protected only in a low extent against overvoltage. A
contact with 230V will destroy the module. The sensor terminals are on the N potential,
which means they are not decoupled from the electrical isolation. That´s why you must
make sure, that a protection against contact for the user in every operating condition is
ensured. The push-buttons from all of the approved switch panel systems ensure this
protection.
The module has three sensor connections, which can be used as additional switchings, if
necessary as actuator. The functions can be programmed with the setup programme LCN-
P or LCN-PRO:
T-connection:
Over a LCN-T8 or push-button converter (LCN-BT4H/BU4L), max. 8 conventional push-
buttons can be evaluated. Apart from that, there are a selection of sensors that can be
connected here alternatively. The module has the required analogue value processing with
up to 12bit accuracy.
I-connection:
Here the IR-receiver for the remote control can be connected, additionally the binary
sensor LCN-B3I, the motion detector LCN-BMI, the transponder reader LCN-UT and the
temperature sensor LCN-TS. These components can be operated parallel on the I-
connection by using the LCN-IV.
The I-connection can alternatively be served as a counter for pulses up to 1kHz, when no
further periphery is connected.
