KNACRO signal generator is designed to simulate 0-10V voltage signal and 0/4-20mA current signal for PLC and panel Debugging, Device Testing, Frequency Converter, Flow Valve, ect. Very easy to use, it can be connected with micro USB-5V power supply or DC 15-30V external power. What's more, it can display 4 different types of digit, 0-10V voltage, 0-22mA current, 0-100 percent and 0-50HZ. It will play a important role in your electronics work.
Power Supply:
External micro USB-5V or external power DC 15-30V, each way makes the generator work; both ways can be connected at the same time.
How to judge whether the module device is active or passive? Common methods below:
1. Internal principle of the device, it is passive if "I+" is 24V+; it is active if “I-“ is 24VG;
2. Use a multimeter to measure the voltag between “I+” and “I-”, it is active if the vaule is 0V; it is passive if the vaule is 24V.
Encoder Knob:
Supports stepless adjustable ratation, better performance and longer service life than normal potentiometer.
Reliable:
Clear LED display.

No matter in PCL debugging or other electronics work, it always simulates the signal you need.
