Description

The current-to-current transmitter TRT is designed to convert alternative current signal coming from current transformers into a standard 2-wire current signal, which is more suitable for transmitting. Together with a current transformer, the TRT unit forms an AC/DC current converter suitable to measure big AC currents up to more than 1000 A. The 4…20 mA output can be used for measuring, regulation, and registration in special control systems. The TRT transmitter is based on modern integrated circuits and is a fixed-range transmitter. Its input ranges cover most popular current transformer output signals (0…1 A, 0…5 A) and customer specified inputs as well. TRT is available in a casing for mounting inside a current transformer, in 2 casings for DIN-rail mounting as well as mounted into an IP65 protection box, as the latter 3 versions can be equipped with an optional input isolation. TRT is an easy-to-use, low-cost, and EMS- protected device. Its application area includes power stations, electrical equipment, and electricity production and distribution. This transmitter can also be used as sensor transducer in various industrial control systems and everywhere, where AC to DC current conversion is desirable.
