• Conversion Of Engineering Quantity Display :Signals are displayed as physical or engineering (ie pure quantity) values,The physical quantity corresponds linearly with the engineering quantity.For example: the current signal of 4~20mA corresponds to 0~100, that is, 4mA corresponds to 0, 12mA corresponds to 50, and 20mA corresponds to 100. This range can be modified by parameters.
• Signal Conversion : The input signal is converted into an output signal, which can be converted between different physical quantities; for example: the input frequency signal is converted into a current signal, and the input range is 0-1000hz into 4-20mA.
• Programming Output : It has the output function of automatically and continuously changing the size according to the setting parameters, and can choose three modes: monotonous rise, monotonous fall and cycle.
• Real-time Curve : The change trend of input and output signals can be displayed by drawing a curve, and the sampling time of the curve can be set.It can also automatically adjust the display curve within the range of the maximum and minimum values within a certain period of time.
• History Record & Firmware Upgrade : Record and view a certain amount of historical data.Support USB emulated U disk for firmware upgrade.
• Preset Value : 4 groups of commonly used signal values can be preset to facilitate quick adjustment of output.
• Modbus Slave : SG-004A can communicate with configuration software or PLC via RS485, set the instrument.
