Function Introduction

[ 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

[ 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-004A can communicate with configuration software or PLC via RS485, set the instrument

[ History Record ]: Record and view a certain amount of historical data[ Firmware Upgrade ]: USB emulated U disk for firmware upgrade

Interface Terminal

• 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

NOTE!!! The safety limit voltage of the input terminal cannot be greater than 30Vpp, and the over limit will damage the equipment

[ Range ]: Select the range of frequency output: 0~99.999Hz, 0~999.99Hz, 0~9999Hz, 0~200kHz

[ Method ]: Select level/open circuit according to the presence or absence of pull-up

[ Output Peak Value]: The level height of the output waveform, the highest is 24V

[ Input Counting Method ]: The rising edge means that the level rises from 0V to the peak value of the pulse, and the counter is incremented by 1. A falling edge indicates that the input level falls to the OV counter and increments by 1.Jump means that as long as the input level jumps up and down, the counter is incremented by 1. Long press [ IN ] to clear the count

[ Frequency Mode Operation Instructions ]: The input frequency range is 0~9999Hz, which cannot be selected, and the displayed decimal point is automatically shifted.The output frequency range can be switched by pressing [ oUt ] when the main interface [ FN ] is white

[ Operating Instructions In PWM Mode ]: PWM displays two parameters, the frequency value (that is, the period value) and the duty cycle.The frequency value will be displayed in the original engineering quantity position (no engineering quantity display).Note that the maximum frequency does not exceed 9999Hz.The frequency value/duty cycle parameters can be set when outputting.When the main interface [ FN ] is white, press [ OUT ] to switch, there is a yellow cursor indication

[ Operating Instructions For Speed Mode ]:

(1) The speed mode is used to calculate the speed of the motor or gear. One revolution of the motor or gear produces 1 pulse, one minute is 3000 revolutions, so 1 second is 50 pulses

(2)[ Time Unit ]: Frequency=RPS(per second)*number of pulses per revolution, RPM(per minute)=RPS*60, RPH(per hour)=RPS*3600.In the speed setting selection, note that the maximum frequency does not exceed 9999Hz

(3)[ Number Of Revolution Pulses ]: The number of pulses per revolution of the motor or gear, which can be selected in the speed setting

(4) [ Tooth Missing ]: It is mainly used to simulate the engine speed, select it in the speed setting

[ Quantitative/Counting Mode Operation Instructions ]: The main purpose of pulse quantitative is to simulate the quantitative control sensor of flow, and the pulse count is to simulate the flow of count.For inputs, the input frequency value will be displayed in the original quantity position.For output, the cycle is displayed at the original engineering position, and the unit is milliseconds.When the main interface [ FN ] is white, press [ OUT ] to switch between cycle and quantitative values, which are distinguished by cursors.

The period value can be modified during quantitative output.In this mode, when the cursor disappears after the output is turned on, the backlight of the up, down, left, and right keys will turn blue.The function of the up, down, left, and right buttons will also change, that is, the up is a single pulse sent.Down is program stop and reset, left is no function, right is start/pause

(1) Loop 1: After starting the output, 24V voltage is output between the (OUT) port and (COM) port, and the loop current is detected at the same time, and the current is displayed in the “output 24V loop” area.This function can be used to test, for example, pneumatic control valves or two-wire transmitters, supply them with 24V power supply and detect current

(2)Loop 2: After activating the independent 24V power supply.The (IN-) port outputs 24V voltage between the (24V) port and the (COM) port.It does not affect the detection type of the input signal by the (IN+) port.In this case, select mA for the input signal type.Then the (IN-) port can be combined with the (IN+) port to form a 24V output,And at the same time detect the current loop.The function is similar to the circuit one

(3)Port (IN-) can be switched to independent 24V power supply function.It outputs a single DC24V voltage, which is the (24V) port at this time.(24V) port used with (IN+) to test two-wire transmitters

©The difference between 24V loop detection and standalone 24V is:24V loop detection output signal port to measure feedback current.

©Independent 24V port and output port can form 24V power supply,It can also be combined with the input (+) to form a transmitter to supply power and measure the feedback current of the transmitter

[ Mode switch ] :When the main interface [ FN ] is white.Press [ OUT ] to switch the display position of output actual loop current value and engineering quantity [ Activate independent 24V ]: After this item is checked, the independent 24V
