FUNCTION

The BASI intelligent isolated transmitter BTT786, is available in casings for in-head and for DIN-rail mounting as well as mounted into an IP65 protection box. This transmitter allows the user to: select sensor and input signal type; select and adjust input range; perform offset correction and device calibration; specify input ranges and output type (4 to 20 mA or 20 to 4 mA); select decimal point position and measurement unit; select output reaction at sensor break; adjust the digital filter. The BTT786 transmitter is easy to program via the specialized configuration software "TraCon". Thanks to its large capabilities and low price, BTT786 can be very useful in various industrial field applications requiring signal isolation.
