Transmitter Module PTM330C

The radio transmitter module family PTM 330 from EnOcean enables the implementation of wireless sensors and switches without batteries. Functional Principle When an energy pulse is supplied (e.g. by the motion energy harvester 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 structures 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. There are three frequency variants – PTM 33x in 868 MHz, PTM 33xC in 315 MHz and PTM 330U using 902.875MHz.
