The intelligent isolated transmitter TRH is a programmable 2-wire HART device with 2000 V input/output isolation level. It is available in case prepared for mounting in 33 mm sensor heads, plastic protection box, and different Ex housings. The transmitter allows the user to program various input and output features including input signal type and range, output offset and calibration, reaction at sensor failure, fixed output current, digital filter, etc. TRH can be ordered with intrinsically safe option for Ex applications. The transmitter is easy to program via HART modem over the current loop using free configuration software "HartTemp". Thanks to its large capabilities and low price, TRH can be very useful in various industrial field applications requiring signal isolation and HART communication.
