RS485 bus 1 and 2 level wireless repeater

1 and 2 level wireless repeater with small antenna. Only 0.6 watt standby loss. If required, a wireless antenna FA250 can be connected. Modular device for DIN-EN 60715 TH35 rail mounting. 1 module = 18mm wide, 58mm deep. This repeater is only needed if the building conditions prevent undisturbed reception or the ­distance between the wireless pushbutton and receiver is too great. Antenna FA250 with a 250cm cable or FAG55E- with a 100cm cable can be connected instead of the enclosed small antenna. When positioned in the optimal location, it can increase range considerably. The 1-level mode is activated ex works. Only the signals from sensors and actuators are received, tested and retransmitted at full transmit power. Wireless signals from other repeaters are ignored to reduce the data volume. In de-energized state it can be switched to 2-level mode with a rotary switch. After switching on the supply voltage, the wireless signals of another 1-level repeater are now being processed. A signal can then be received and amplified maximum 2 times. Wireless repeaters need not be taught-in. They receive and amplify signals from all wireless sensors within their reception area. The LEDs under the rotary switch indicate all the wireless signals detected by briefly flashing. The wireless repeater FRP14 can be installed either as a single device in a subdistributor panel. It then requires a 12V power supply from a switch mode power supply unit SNT12-230V/12V DC-1A. Or it is installed together with remote Series 14 wireless actuators and cross-wiring requires a jumper. There is no connection to the bus. It is only looped through.
