Générateur de Signaux Sg-004a, Simulateur Source Courant-Tension Analogique Réglable 4-20 Ma 0-24 V, Courbe en Temps Réel et Enregistrement

Key Features：
Engineering Unit Conversion & Linear Scaling – Displays physical or engineering values; easily map a 4-20mA signal to a 0-100% scale. Adjustable range lets you set 4mA = 0, 12mA = 50, and 20mA = 100 for intuitive readings.

Versatile Signal Conversion – Converts any input signal into a different output signal type across physical quantities. For example, transform a 0-1000Hz input into a proportional 4-20mA current output, ideal for system integration testing.

Programmable Auto-Ramp Output – Automatically varies the output signal according to your settings. Choose from monotonic rise, monotonic fall, or cyclic modes to simulate dynamic process conditions without manual adjustment.

Real-Time Curve & History Record – View input/output trends with a live curve display; sampling time is configurable. Built-in memory stores historical data for later analysis, helping you track performance over time.

USB-C Powered & Portable – Internal 3000mAh rechargeable battery provides up to 24 hours of standby. Supports USB emulated U-disk firmware upgrades, keeping your device current. Compact (82x28x112mm) and lightweight (66g) for field use.
