Outdoor radio repeater 1- and 2-level, 60 x 46 mm, 30 mm deep. Standby loss is only 0.7 watts. Supply voltage is 230 V. This repeater is only necessary if the structural conditions prevent uninterrupted reception or if the distance between the radio button and receiver is too great. The 1-level mode is activated by default. It only receives, checks, and retransmits signals from sensors and actuators at full transmission power. Radio signals from other repeaters are ignored to reduce data volume. By removing the cover (loosen the two screws on the front) and repositioning the jumper to the right, it switches to the 2-level mode. Now, the radio signals from another 1-level repeater are also processed. A signal can be received and amplified a maximum of 2 times. A red LED indicates all detected radio signals by briefly flashing. Radio repeaters do not need to be taught. They receive and amplify signals from all radio sensors within their reception range. For the waterproof power connection, there is an M12 screw connection on the underside. The protection class is IP54, and the permissible ambient temperature ranges from -20 °C to +55 °C. Installation is done by screwing it on.
