Product features:
1. This module is divided into two versions, the signal generator and the version with MODBUS function
2. Multi-function support PWM mode, pulse mode, signal source, signal source mode, sine wave mode, support RS485 Modbus communication
3. The module signal source mode has voltage and current calibration function
4. PWM mode voltage, frequency, duty cycle are adjustable
5. Signal source mode voltage source 0-10V adjustable, current source 0-20mA adjustable
The difference is that the power supply with MODBUS version has RS485 communication interface, which can be set up with the upper computer software or collect data, and can also communicate with computers, PLC, DCS, smart meters and other devices! In addition, other functions are the same!
Product parameters:
Power supply voltage: DC 7-24V
Product function: PWM mode, pulse mode, signal source mode, sine wave mode
PWM mode: voltage, frequency, duty cycle are adjustable, frequency accuracy up to 0.1%; voltage range: 1-24V adjustable, frequency range: 1Hz-150KHz adjustable, duty cycle range: 0.1-100% adjustable
Pulse mode: time accuracy 0.001S, start delay time T0:0.001-60S, high level time T1:0.001-60S, low level time T2:0.001-60S, pulse number PulseNun:1-60000 (unlimited output when number is set to 0)
Signal source mode: voltage source 0-10V adjustable, current source 0-20mA adjustable (Note: the load is not greater than 250R)
Sine wave mode: 1-1000Hz adjustable, note: voltage peak to peak for about 5V can not be adjusted
Signal load capacity: the maximum output current 30mA (Note: this product is the output is a signal source, can not directly drive high-power load. If you want to use the PWM signal to drive high-power loads, such as motors, LEDs, etc., can be connected externally to the driver module)
Ambient temperature: -10-+70℃
Module size: length 79mm width 43mm height 41mm
Opening size: 76mm long by 39mm wide
Restore factory settings: in case of power failure, press and hold P1, then power on and then release, it will be restored.
Calibration function: The module signal source mode has voltage and current calibration function, if the display is not allowed, the following method can be used to calibrate: first power off, press and hold the code switch to power up, it will enter the voltage and current mode, use a multimeter to measure the output voltage (amount GND and 2-10V) or current (amount GND and 4-20MA), rotate the adjustment to the display and multimeter, press the code switch to save, three seconds after power off. Three seconds after power off can be, the accuracy can be calibrated to within 0.1%!
PWM mode: press P1 once to enter, press SET key to switch to set voltage, frequency, duty cycle data in turn (duty cycle can also be adjusted directly rotary encoder, no need to enter SET mode), rotary encoder can adjust data (short press to switch coarse adjustment, fine adjustment), the signal is real-time output during the adjustment process, adjust data to complete press SET key to exit, short press encoder to exit SET state Turn on or off the output.
Pulse mode PULSE: Press P2 once to enter, press SET to switch the setting voltage, time T0\T1\T2, number of pulses, rotary encoder can adjust the data (short press to switch coarse and fine adjustment), the signal is output in real time during adjustment, press SET to exit when the adjustment data is finished, short press the encoder to turn on or off the output when exit SET state. Note: The voltage of pulse mode and PWM mode is the same, switch to PWM mode to adjust the voltage when you need to adjust it.
Voltage and current signal source mode: Press P3 once to enter, press SET key to switch to set voltage and current in turn, enter that is to start output signal, rotate the encoder to adjust the data (short press to switch coarse adjustment, fine adjustment), the signal is output in real time during the adjustment process, adjust the data to complete press SET key to exit. (Note: 4-20mA current source output when the load can not be greater than 250R)
Sine wave mode: press P3 twice to enter sine wave, enter that is to start output signal (peak to peak is about 5V, voltage is not adjustable), rotary encoder can adjust the frequency, the signal is output in real time during the adjustment process.
