The intelligent non-isolated transmitter TRB, manufactured by COMECO, is available in case prepared for mounting in Ex housings, in casing for in-head mounting, and in another for DIN-rail mounting, as well as mounted into an IP65 protection box. This transmitter allows the user to:
The TRB transmitter is easy to program via the specialized configuration software “TraCon”. Thanks to its large capabilities and low price, TRB can be very useful in various industrial applications requiring temperature conversion before subsequent measurement and control.
