4-20mA/0-10V Signal Generator – High-Precision Handheld Current & Voltage Loop Simulator for PLC & Panel Debugging

Designed for automation professionals, control engineers, and maintenance technicians, the 4-20mA/0-10V Signal Generator is a compact, high-precision analog signal simulator used to generate and test current (0-20mA, 4-20mA) and voltage (0-10V) signals. Whether you're calibrating field devices, simulating transmitters, or debugging PLC input modules, this handheld loop simulator is the ultimate tool for fast, reliable signal verification in industrial environments.

This portable device streamlines troubleshooting in control systems, allowing users to manually adjust analog output signals and confirm real-time system responses without needing a live sensor or field input. Built for field and lab use, the generator offers both fine-tuned accuracy and rugged simplicity.

Key Features:
