【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 4mA~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 4mA~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.
