The JS-VISG-M-S is a versatile, high-precision voltage and current signal generator widely used for testing PLCs, industrial equipment, and valve adjustments. This pocket-sized simulator provides both 0-10V and 0-22mA signals, making it an essential tool for field engineers. Key Technical Specifications
Understanding the hardware capabilities is the first step in using the device effectively:
Power Input: Supports DC 15-30V (terminals) or 5V Micro-USB (power bank/PC).
Internal Battery: Often features a 3.7V 1000mAh lithium battery for portable use.
Voltage Output: Adjustable from 0-10V with a precision of 0.01V.
Current Output: Adjustable from 0-22mA with a precision of 0.01mA.
Display: A 4-digit LED screen that shows values with two decimal places. Wiring & Connection Guide
Proper wiring prevents damage to the simulator or your PLC control system:
Power: Connect external 24V power to the terminals labeled 24V+ and GND.
Voltage Output: Use the AVO (Voltage Output) and GND terminals.
Current Output: Use the AI+ and I-MODE (or COM) terminals for current loop simulation. Operational Instructions
The device is controlled via a single encoder knob with a 360-degree stepless rotation:
Adjusting Values: Rotate clockwise to increase and counter-clockwise to decrease.
Saving Output: Briefly press the knob to save the current value. The screen will display "..." to confirm, and the device will restart with this value next time. js-visg-m-s manual
Switching Modes: Use the small "MODE" button to toggle between voltage and current display modes. System Parameter Settings (F-Menu)
To access advanced settings like calibration or range adjustments, you must enter the parameter menu:
Enter Menu: Press and hold the knob for 2 seconds until "F001" appears.
Input Password: Many devices require the password + - - + (one clockwise pulse, two counter-clockwise, one clockwise) to unlock restricted parameters like F002. Common Parameters:
F001: Toggle between Coarse (0) and Fine (1) adjustment modes. F002: Set the output range (e.g., 0-10V, 4-20mA, or 2-10V).
F003: Change the display mode from real value to 0-100% percentage or 0-50Hz.
