SG002 Handheld Signal Generator & Loop Calibrator – 0-10V / 4-20mA Current & Voltage Simulator for PLC Testing

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.

Technical Specifications ⚙️

Who is this for?

• PLC Programmers: Test your analog input logic (scaling) without needing real sensors.
• Industrial Electricians: Troubleshoot faulty 4-20mA loops or check if a VFD (Variable Frequency Drive) responds to speed commands.
• University Labs: An affordable way to teach students about industrial signal standards.
