Riiai DC 0-10V 0 /4-20mA Current Voltage Signal Generator, Built-in Battery Power Supply Interface Analog Simulator, Adjustable 4-Digit Display, for PLC, Panel Debugging, Device Testing

Features

• 2-in-1 Voltage & Current Generator Voltage Output: -10V~+10V, precision is 0.01V, current output: 0-22mA, precision is 0.01mA, rotate the encoder knob to adjust the output voltage and current, switchable and adjustable, can be calibrated. The encoder knob rotates one circle and has 20 pulses
• Multiple 4-Digit Display With 4 different types of digit displays and two decimal points, you can press the "Mode" button to switch the display mode between voltage and current. You can also follow the instructions to switch the 0-100 percent or 0-50 HZ display
• Different Power Supply Modes With a 1000mAh, 3.7V, built-in rechargeable battery embedded inside (charged via a micro USB port), it can be powered in various ways: micro USB-5V or external power DC 15-30V, each of which can make the signal generator work
• Safe to Use Output range: passive or active 0-22 mA, -10~+10V, the voltage output can be exactly 0.00V; output range and precision are programmable and adjustable. Output with short circuit protection, power supply has reverse connection protection, which is safe for you to use. The user can set 9 x fast signal output points, making it more convenient to do debugging
• Wide Application It can be used for PLC and panel debugging, device testing, frequency converters, flow valves, servo motor speed regulation, light dimmers, etc. With its small size, it is easy and convenient for you to carry it
