One、Overview
XMZ / XMT series of intelligent instruments integrate display, control, transmission and other functions.
Input thermocouple, thermal resistance, standard current, standard voltage signal, can display and control
Temperature, pressure liquid level, speed, pH, PH and other physical quantities.
XMZ / XMT is widely used in thermal, chemical, mechanical and electrical equipment, municipal engineering,
Building automation and other industries are ideal products for forming various automatic control systems.
Two、Features
◆ Modular design, SMT process, high-performance switching power supply
◆ 19 kinds of signal compatible input, the range and decimal point can be set and corrected arbitrarily
◆ The input signal is selected arbitrarily. The thermocouple input comes with cold junction temperature compensation.
◆ Isolated current and voltage transmission output (12-bit resolution), the output range can be set arbitrarily
Three
Limit control, relay pull-in value and release value (with hysteresis) can be arbitrarily set
