Interface Terminal - Fnirsi SG-003A Operating Manual

【 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
【 2.3 】 Interface Terminal
Output－
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
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
