Overview 📝
The SG002 Signal Generator is an essential diagnostic tool for anyone working in industrial automation. It allows you to simulate the analog signals used by industrial equipment (0-10V or 4-20mA. Instead of waiting for a temperature sensor or a flow meter to be installed, you can use the SG002 to send a “fake” signal to your PLC to ensure your code and wiring are correct.
Key Features ✨
Active & Passive Modes: Can simulate both 2-wire (passive) and 4-wire (active) current loops, making it compatible with almost any industrial input.
High Precision Display: Features a clear, backlit LCD that shows the exact voltage or current output down to two decimal places.
Step & Sweep Functions: Easily switch between common values 4mA, 8mA, 12mA, 20mA or use the smooth adjustment knob for fine-tuning.
USB-C Rechargeable: No need for 9V batteries. The built-in lithium battery ensures long-lasting operation in the field.
Pocket Size: Lightweight and durable, designed to live in an electrician’s tool pouch.
