WFSG-06 Sine Wave Signal Generator 4-20mA 2-10V PWM Adjustable Module with Function For Modbus RS485

WFSG-06 Sine Wave Signal Generator 4-20mA 2-10V PWM Adjustable Module with Function For Modbus RS485

Version Description:
This module is divided into two versions, signal generator without function for MODBUS and the version with function for MODBUS.

The difference is that the power supply with function for MODBUS has RS485 communication interface, which can be set or collected by a host computer software, and it can also communicate with computers, PLC, DCS, smart meters and other devices! In addition, the other functions of the two versions are the same!

The multifunctional adjustable signal generator supports PWM mode, pulse mode, signal source mode, and sine wave mode.

Reset:
In the case of power failure, press and hold P1 button without releasing it. Then power on and release the button to restore factory settings.

Calibration Function:
The signal source mode of the module has a voltage and current calibration function. If the display is inaccurate, you can use the following method to calibrate: first power off, press and hold the code switch to power on, it will enter calibration voltage and current mode. Use a multimeter to measure output voltage (measure GND and 2-10V) or current (measure GND and 4-20MA), turn the knob to adjust the display to make the display consistent with the multimeter, press the code switch to save, and power off after three seconds. The accuracy can be adjusted to within 0.1%!

PWM Mode:
Press P1 button once to enter. Press SET key to switch and set voltage, frequency, and duty cycle data in turn (you can also directly rotate the encoder to adjust the duty cycle without entering SET mode). Rotary encoder can adjust data (short press to switch between coarse and fine adjustment). Signal is output in real time during the adjustment process. After adjusting the data, press SET key to exit. When exiting the SET state, short press the encoder to start or close output.


Pulse Mode:
Press P2 button once to enter. Press SET key to switch setting voltage, time T0/T1/T2, pulse number in turn, and the rotary encoder can adjust data (short press to switch between coarse and fine adjustment). Signal is output in real time during the adjustment process. After adjusting the data, press SET to exit. When exiting the SET state, short press the encoder to start or close the output.


Voltage & Current Signal Source Modes:
Press P3 button once to enter. Press SET key to switch and set voltage and current in turn, and start to output the signal when it is entered. Rotary encoder can adjust data (short press to switch between coarse and fine adjustment). Signal is output in real time during the adjustment process. After adjusting the data, press SET to exit.

Sine Wave Mode:
Press P3 button twice to enter the sine wave mode. After entering, it starts to output signal (the peak is 5V, the voltage is not adjustable). Press SET key to adjust frequency. Rotary encoder can adjust data (short press to switch between coarse and fine adjustment). Signal is output in real time during the adjustment process. After adjusting the data, press SET to exit.

Communication Function:
- Signal generation module version for Modbus: Support for RS485 interface Modbus RTU communication protocol
