2.1.1.2 Description
The 750-642 Radio Receiver module receives digital and analogue sensor
signals from the field area by radio link.
Danger
The radio receiver modules must not be used in any relation with equipment
that supports, directly or indirectly, human health or life or with applications
that can result in danger for people, animals or real value.
This results from the classification of the radio receiver module in class 2
Equipment according to ETSI EN 301 489-3 V1.4.1 (2202-08) "Specific
conditions for short-range devices (SRD)".
The module receives the radio transmitter data via an antenna with a carrier
frequency of 868.3 MHz situated outside the enclosure.
For this an antenna equipped with an SMA plug (WAGO RF ANTENNA
868 MHz/SMA, Item-no.: 758-910) is connecting to the SMA socket fitted to
the module.
Attention
The WAGO RF-ANTENNA 868MHz/SMA is not included in delivery of the
Radio Receiver module!
It is to order separately as accessories under the Item-No.: 758-910.
The module has two potential free CAGE CLAMP®connections (1 and 2)
without electrical function. These make the mechanical fixing of the antenna
line possible.
Attention
Mechanical stress such as vibration or shock may cause wire breakage. For
that reason, appropriate action needs to be taken to fix the antenna cable (see
chapter 2.1.1.9 "Installation in Case of mechanical Stress (Vibration,
Shock)".
The applications for this module are, for example, in operator, control and
signaling systems in building automation (office, exhibition halls, private
households...), in cabin automation on ships, and anywhere sensors (radio
transmitters) require intelligent controllers or gateways to other bus systems.
The revolutionary EnOcean radio technology offers the decisive advantage
that the specially developed sensors have very low power consumption.
They require no external power supply or batteries for radio transmission. This
means that the sensors need no servicing (battery replacement), can be
installed retrospectively without difficulty and, due to the wireless technology,
can be freely positioned, even on glass facades.
For the necessary electrical energy, the sensors use either mechanical energy
converted by piezo elements or solar energy. This provides sufficient energy
for the respective sensor to send a unidirectional radio signal.
The number of sensors can be chosen virtually at will, although the maximum
per module is around 100 sensors due to increasing density with growing
numbers.
