Supported Power Supply:
- DC15V-30V external power supply; can share the 24V power supply of PLC and other equipment.
- Support for Android (micro USB) universal interface; can be connected to power bank/charger/computer USB port, etc.
- As long as one power supply is connected, the signal generator can work. The device can also be connected to multiple power supplies at the same time.

New Functions (compared with the first generation):
- The voltage output range is increased from the original 0-10V to ±10V (settable), which is convenient for debugging CW and CCW
- It can output 0V, and its performance far exceeds that of single-power products. Control dimmer can be completely off, and motor speed can be completely static.
- The shell is made of ultra-thin frosted ABS. Its upper and lower covers are seamless, and the hand feel is good
- The software adds custom quick adjustment function. It can be set to output only a few values, which is convenient for quick debugging and production

Features:
- Default output range 0-10V/0-20mA. The output voltage can be set to 0-10V, 2-10V, 0-5V, 1-5V, 0-3.3V, 0-2.5V, 0-1V, ±10V, ±5V and -10V to 0V. The output current can be set to 0-20mA, 4-20mA and 0-22mA
- Settable display mode: actual voltage and current, 100.0% display, 50.0Hz display and other customized display methods
- Can be wired and output in passive and active modes. Support 2-wire, 3-wire and 4-wire connection. Can directly simulate passive 2-wire pressure sensor, temperature sensor, etc. Can be connected to active 3-wire, 4-wire PLC, inverter, servo driver and flow valve, etc.
- Output with short-circuit protection and 24V input reverse connection protection
- Support several power supply means
- One-key switch to adjust voltage and current; independent wiring and simultaneous output
- Coarse and fine adjustment modes; adjustable number of turns
- Custom quick adjust mode
- 0.4" 4-digit bright digital tube, 0.01 precision adjustment, output can be calibrated
- Ultra-thin matte non-slip shell with good touch feeling and elegant appearance. High-grade aluminum alloy knob and electroplated button
- Linear output; calibratable accuracy
- The encoder knob enables stepless adjustment, and its performance and service life are better than those of ordinary potentiometers
- Imported chips ensure long-term stability
- Power-on output value can be save when it is power-down. Press the knob to save the value
- Application: Can be used for continuous speed regulation of servo motor forward and reverse, the dimmer light cannot be turned off, and the motor jitters

Technical Parameters:
- External power supply DC15-30V and power 1W (not charging)
- External micro USB-5V 0.2A (not charging)
- Adjustable output voltage ±10V, accuracy 0.01V, and error 0.5% can be calibrated; maximum current 20mA, with short-circuit protection
- Adjustable output current 0-22mA, accuracy 0.01mA, and 0.5% error can be calibrated. The current sampling resistance is 10-500Ω, which can be short-circuited
- The digital tube displays 4 digits and two decimal places
- Encoder knob 20 pulses per turn
- Working environment: 0-40℃ and relative humidity < 80%

Package Included:
- 1 x Signal Generator

Note:
- It comes without battery.
