Product Details

Wireless Transmitter Module PTM 330

The PTM 330 is a compact low-power ISM-band transmitter module which when used in conjunction with the ECO 200 energy harvester, can be a batteryless wirefree transmitter or alternatively a battery powered transmitter consuming very small amounts of power. When a short energy pulse is supplied to the PTM 330 module an RF 'telegram' is transmitted including a 32-bit module ID and the polarity of the supply voltage. Status of the four digital inputs is also transmitted.

Unique encoding and pairing is interference resistant with a unique 32-bit identifier
Pre-installed whip antenna

Batteryless Wireless Applications

EnOcean manufacture a range of transmitter and receiver products that operate in the 868MHz area of the ISM band. These devices are typically very efficient in terms of the power supply requirements and are used to send short messages.,The advantages of EnOcean technology are clearly illustrated through applications such as electrical control which eliminates the need for external wired connections and batteries.,Suitable for limitless applications where maintenance free and flexible switching needs to be installed without drilling, cabling and reconstruction costs.,Power in the transmitters is also created for "FREE" using energy harvesting techniques to create energy from the push button switches or solar power for its sensors transmitters.,Radio systems based around EnOcean technology can be formed into star, mesh, or hybrid topology networks, and are a good complement to ZigBee systems, typically in building automation and remote sensor applications.
