【 Preset Value 】 : 4 groups of commonly used signal values can be preset to
facilitate quick adjustment of output
【 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
【 Modbus Slave 】 : FNIRSI SG-003A can communicate with configuration software
or PLC via RS485, set the instrument
【 Firmware Upgrade 】 : USB emulated U disk for firmware upgrade
When the (IN-) port is an independent power supply, it can be called a (24V) port,
and it forms an output port pair with the (COM) port
The safety limit voltage of the input terminal cannot be greater
than 30Vpp, and the over limit will damage the equipment

【 Interface 】
There are 4 inner diameter 4mm wiring ports on the top surface, which are
represented by different color rings
The blue port (IN-) is an alternate function, and it is also an input-, which can be
switched to a 24V independent test power supply.The (IN-) port is internally
shorted with the black (COM) port in the input state.When the (IN-) port is an
independent power supply, there is a 24V voltage between the (COM) port
Red (OUT) port and black (COM) port form an output port
Yellow (IN+) and blue (IN-) form the input port
