The TRN-1/400 transmitter allows to power a camera with thermostat and transmit video signal from the camera by twisted pair cable (UTP, FTP). Video signal from the camera is put to the TRN-1/400 transmitter input, and transmitted by twisted pair cable to the TRO-4/400 M1670 receiver or the TRO-1/400 M1669 receiver. Both he transmitter unit and the receiver unit adapt 75 ohm coaxial cable impedance to twisted pair cable impedance. It guarantees video signal transmission up to 400 meters.
The TRO-1/400 M1669 receiver supplies un-stabilized voltage (max. 40V DC) to twisted pair cable, and the TRN-1/400 transmitter converts it into 12V DC stabilized voltage. It allows to power the camera and the thermostat. Assuming that the power consumption of the camera is 250mA, and 500mA for the thermostat (TT-12E) , the voltage can be sent over the following distances:
