Product introduction: The instrument is divided into three categories by thermocouple, thermal resistance and linear input. Each type of signal can be determined by the user configuration of the sensor type (or the upper and lower limit of the engineering unit).

High precision A/D conversion, SMT production process.

Open user menu form, English prompt, panel operation, easy to use.

Isolated output 4 ~ 20mA transmission function or isolated 24 vd.C power distribution function (optional).

With two relay alarm output, each can be arbitrarily set to the upper and lower limit alarm, alarm value can be set in the full range, at the same time can be set alarm insensitive area.

Adopt E2ROM memory, watchdog circuit. The instrument has strong anti-interference ability, and the parameters can be preserved for a long time after power failure.
