## Features

- High-Precision 4-20mA Current Output: The two-wire current loop 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 current loop signal generator 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 two-wire current loop signal generator 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.

## Questions & Answers

**Q: Does anyone have a pdf of the datasheet that comes in the box? ours was damaged and i'd like to keep a record of it for future reference.**
A: I probably can find one, but it's worthless. I tried to figure it out (no dice) then took it to the local motor shop and they didn't understand it either. Typical chi-com gibberish with no explanation of what it does or how to hook it up. They said bring in the VFD and that thing and we can probably get it working...if it works at all.

**Q: Is the supply voltage (15v -30v) put in line with the current wires or are there separate terminals for that? The pictures dont show any?**
A: I use this to simulate a 4-20mA sensor(in my case a 24v current loop) 

I do not need a separate power supply as the 2 wire current loop is both the power supply and the signal path. 

I would consider a different device if you need to supply power to something. There are many other devices like this that use a power supply and send out voltage or current.

**Q: What is the display mode setting for the current loop simulator?**
A: This current loop simulator has 3 display modes: Actual Current/Percentage/Hertz.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Simple, Small and works great!
*by J***F on April 21, 2021*

This 4-20ma generator is live.You do not have to press the button to save the output.As you scroll up - so does the output.Is small form is great.I like that fact that this one is Loop Power!I will be buying more to add to my PLC Stand.

### ⭐⭐⭐⭐⭐ Works as expected. Simple as could be.
*by H***Y on February 14, 2024*

Works great for troubleshooting or building out loop receivers.

### ⭐ Buy a more expensive tester.
*by N***S on July 22, 2025*

Broken upon arrival. No matter the direction of voltage input screen will not light up, when in line with my current input voltage drops to 3.2v. I also tested with my other sensors to be sure the card was wired correctly, this device is none functional at best.
