The 750-642 Module receives radio telegrams from maintenance-free, self-powered and wireless switches/sensors based on EnOcean radio technology. This module can be operated with any controller within the WAGO I/O System 750. Preprogrammed function blocks make integration easy. The energy required for switch or sensor operation is produced by converting one type of energy (heat, solar or mechanical energy) into usable electrical energy. The radiated energy from the transmitter modules is approximately one million times smaller than mobile phones. Almost any number of sensors is possible. However, the maximum number is around 100 transmitters per module due to the increasing density of switches/sensors. Four billion code numbers provide for clear transmitter/receiver assignment. Repeated, time-shifted transmission of the radio telegrams, at very short transmission times, results in a high level of protection against external interference. The maximum transmission range is 300 meters in open field. Depending on building materials and spatial geometry, the range may be reduced to typically 30 meters (see manual for more information). To assess the transmission path, the LED (RSSI) indicates a sufficient input level. *Documentation available in German and English. An SMA socket is used to connect an external antenna to the housing. The external magnetic-mount antenna (758-910) features a 2.5 m long coaxial cable and SMA plug (available as an accessory).
