This series of instruments uses standard Modbus protocol (RTU mode) can be directly connected to all domestic and foreign manufacturers of configuration software, without having to create a driver, excellent versatility. This series of instruments with multiple types of input, an instrument can be connected with different input signal (thermocouple / RTD / Linear voltage / linear current / linear resistance), greatly reducing the number of backup table. Can be used with various types of sensors, transmitters used in conjunction to achieve the temperature, pressure, level, flow and other physical measurement and display, and with a variety of actuators, electrical and electromagnetic heating equipment, electric valves PID regulation and control . This series of instruments up to four optional relay alarm output, one control signal output, also matching the current transmission or a standard communication interface (RS485 or RS232C) output. This series of instruments is very powerful and has many types of input, zero and full-scale correction, thermocouple cold junction compensation digital, digital filtering, communication or transmission, dual-column display, setpoint limit, external input switching dual setpoint , key lock, slow start, heated power segment limit, heating circuit break alarm, valve stroke time is free to set other functions; in addition, there are four instruments with alarm output delay function, and each alarm can be independently set upper and lower limits, positive deviation, negative deviation, etc., the first and second alarm output can also be set for the event output can directly control their start and stop by parameter setting (or communication settings).
