The intelligent isolated transmitter TRBI, 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:
TRBI is easy to program using the specialized “TraCon” software. Thanks to its large capabilities and low price, TRBI can be very useful in various industrial field applications requiring signal isolation. Technical specifications
