PTM 230
Radio transmitter module
The radio transmitter module PTM 230 from
EnOcean enables the implementation of battery-less radio switches for applications in
e.g. building technology or industrial automation. Power is provided by an external
electro-dynamic power generator such as
ECO 100 or a short energy pulse.
Functional Principle
When a short energy pulse is supplied to the
PTM 230 module an RF telegram is transmitted
including a 32-bit module ID and the polarity of
the supply voltage. In addition the information of
2 inputs is transmitted. With these 2 inputs one
rocker of a PTM 200 can be simulated.
