JS-420ISG-V2 Precision 4-20mA Signal Generator – Accurate, Programmable, Easy to Use
The JS-420ISG-V2 is a two-wire current loop signal generator designed for electronics enthusiasts, educators, students, and makers who need precise current source for testing and experimentation. It delivers stable output with ±0.5% accuracy and 0.01 display resolution—ideal for hobby workshops, university labs, and electronics repair benches.
Flexible Output & Real-Time Display
Switch between 4-20mA and 3-21mA output ranges. The LCD screen clearly shows current value in mA, percentage, or Hz. The rotary encoder allows smooth, continuous adjustment without the stepping limitations of push-button devices.
Linear Output Alignment
The built-in linear output adjustment function lets you match the generator’s output to the reading of your test meter or display module. This ensures accurate signal simulation for component characterization and circuit debugging.
Smart Memory & Programmable Presets
Save time with 2 to 9 programmable output presets. Choose between automatic storage (last used value) or manual storage (user-defined presets). Recall them instantly via the rotary encoder—perfect for repeated experiments and multi-point testing.
Simple Wiring, Wide Compatibility
No need to worry about polarity. The terminals are non-polarized, making connections quick and error-free. Operating voltage: 15-30V DC. Sampling resistance:
