Features: This signal can use 4-20mA to generate voltage and control the current in the circuit. Accuracy up to 0.01; Liquid crystal display; Rotary encoder adjustment Two connection terminals are non polarity. Output range can be set; 4-20mA (device control) / -21mA (signal debugging) Display mode can be set, it is convenient for you to see the value Linear output can be calibrated; The actual output can be consistent with the display of customer device. Output storage: automatic storage & manual storage. 2-9 programmable outputs: just rotate the encoder to set. Specification: Item Model: JS-420ISG-V2 Supply Voltage: 15 - 30V Output Range: 4 - 20mA / 3 - 21mA Display: Actual Current / Percentage / Hz Sampling Resistance: ＜500 Ω Output Accuracy: 0.5% Display Accuracy: 0.01 Color: Shown As Pictures Size: Approx. 8 * 4.2 * 4.5cm / 3.14 * 1.65 * 1.77inch Weight: 44g Type: Signal Package List: 1 * Signal 1 * Manual

• 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.
