Gives you the variety
The OPTITEMP TT 51 series consists of 2 different versions. OPTITEMP TT 51 C is primarily intended to be mounted in DIN-B housing, whereas OPTITEMP TT 51 R is the rail-mounted version. The standard redundancy of both transmitters comes in 2-wire and 3-wire circuits with thermocouples and resistance thermometers. The rail-mounted device is the only temperature transmitter currently on the market to feature the option of a redundant 4-wire connection of RTDs.
