4-way wireless transmitter module. With exchangeable antenna. If required, a FA250 or FAG55E wireless antenna can be connected. Standby loss only 0.1 watts. Modular device for mounting on DIN-EN 60715 TH35 mounting rail. 1 division unit = 18mm wide, 58mm deep. Connection to the Eltako RS485 bus. Cross-wiring of the power supply with a jumper. Alternatively, the power supply can be provided with a 12V DC switching power supply at the +12V/GND terminals. This wireless transmitter module has four channels and can therefore send radio telegrams to the Eltako building radio like a 4-channel wireless button. E1 initiates a radio telegram such as pressing the top rocker of a radio button with a rocker, E2 such as pressing the bottom rocker, E3 such as pressing the left top rocker of a radio button with a double rocker and E4 such as pressing the left bottom rocker of a radio button with a double rocker. The telegram when the control contacts open is identical to releasing the radio button. Several radio transmitter modules must not be controlled at the same time. The universal control voltage at +En/-E processes control commands from 8 to 253V AC or 10 to 230V DC with a length of at least 0.2 seconds. Maximum parallel capacity of the control lines at 230V 0.9 F. This corresponds to a length of approx. 3000 meters. If terminals E1 and E2 are connected with a bridge, a radio telegram is sent from E2 once per minute as long as the control voltage is present. E.g. for central commands with priority. The rotary switch is required to activate or deactivate the encryption and is set to AUTO during operation. Activate encryption: Turn the rotary switch to the right stop (key position) and press it once. Deactivate encryption: Turn the rotary switch to the left stop (position of crossed-out key) and press once.
