4-20mA Two-Wire Current Loop Signal Generator with LCD Display, 3-21mA Extended Range 0.5% Accuracy Tester for Transducer Calibration, PLC & Industrial Control, Rotary Encoder, Memory Storage
Description
- High-Precision 4-20mA Current Output: The 4-20ma signal generator generates stable 4-20mA or extended 3-21mA signals with ±0.5% output accuracy and 0.01 display resolution; ideal for calibrating transmitters, sensors, PLCs and industrial control systems with reliable two-wire loop simulation.
- Clear LCD Display & Intuitive Rotary Encoder: This current loop signal generator has an easy-to-read LCD screen that shows current (mA), percentage (%) or frequency (Hz); adjust output smoothly and precisely using the rotary encoder.
- Flexible Output Settings & Calibration: The multifunctional signal generator 4-20ma supports linear output calibration to match your device’s actual response; set custom output values from 3-21mA; ensures the generated signal perfectly aligns with the connected instrument’s display for accurate testing and troubleshooting.
- Programmable Outputs & Memory Functions: The current loop signal generator can store up to 8 programmable output values (2-9) for quick recall; supports both automatic and manual storage modes—ideal for repetitive calibration tasks, maintenance checks or multi-point testing without re-entering values.
- Industrial-Grade Design & Wide Compatibility: Terminal design of the 4-20ma current signal generator module is polarity-free (no +/− required), simplifying connections; works with 15-30V DC supply and sampling resistance <500Ω; suitable for pressure sensors, temperature transmitters, flow meters and other 4-20mA loop-powered devices.
