GENERAL DESCRIPTION
1.1
Basic Functionality
The radio transmitter module PTM 330 from EnOcean
enables the implementation of wireless sensors and
switches without batteries.
Key applications are handheld remote controls or indus-
trial switches.
Functional Principle
When an energy pulse is supplied (e.g. by ECO 200 from
EnOcean) an RF telegram is transmitted including a
unique 32-bit module ID, the polarity of the energy
pulse, and the operating status of 4 digital inputs. The
RPS telegram content can be configured if other content is needed.
PTM 330 can be connected to ECO 200 via a contact spring. There are two meander struc-
tures on the PCB which allow usage of a rubber pad to set the level of two digital inputs.
Alternatively PTM 330 can be mounted as an SMD component onto a host PCB. In this case
energy supply pins and digital input pins are accessible via contact pads.
