FTR262

FTR262 is a wireless transmitter that has a universal input and can be powered by using batteries or an 8…30 VDC power supply. The wireless concept and tight enclosure (IP 65) enable easy commissioning, installation and system expansion even in difficult locations and installation sites.

The transmission interval of the FTR262 is programmable from five seconds to five minutes. The device supports the following inputs: Pt100, Ni, Cu, all thermocouples (mV + cold junction temperature), ohms, millivolts, milliamperes and volts (up to 100 V). FTR262 operates in the unlicensed 433.92 MHz frequency band, so it can be used freely in areas where this so-called ISM frequency band is in use, e.g. almost everywhere in Europe.

If you need a longer range or remote reading for transmitters where it is not possible to use mains power, then look at our Solid-Sky devices.
