Riiai DC 0-10V 0/4-20mA Voltage Signal Generator with 4‑Digit Display

Description

Product Overview

The Riiai DC 0-10V 0/4-20mA signal generator is a compact, high‑precision instrument designed for engineers, technicians, and hobbyists who need reliable voltage and current simulation in a portable form factor. Measuring just 5.91 x 3.35 x 1.97 inches and weighing only 4.8 ounces, the device packs a powerful 1000 mAh lithium‑ion battery, a micro‑USB charging port, and a versatile DC input range of 15‑30 V. Its core functionality includes dual output modes: a bipolar voltage range from –10 V to +10 V with 0.01 V steps, and a current range from 0 mA to 22 mA with 0.01 mA resolution. The intuitive 4‑digit display can be toggled between voltage and current readouts, providing clear, real‑time feedback during testing. The unit also features short‑circuit protection, programmable output limits, and a robust metal enclosure that meets industrial durability standards.

Usage

Designed for a wide array of applications, this signal generator excels in PLC and HMI panel debugging, where precise analog signals are required to validate sensor inputs and actuator responses. It is equally effective for testing frequency converters, flow valves, servo motor speed controllers, and light dimmer circuits. The built‑in battery enables field work without reliance on external power, while the micro‑USB charging capability ensures quick recharging on the go. Users can connect the device to a PC or a handheld controller via the USB port for firmware updates or data logging, making it a flexible tool for both laboratory and on‑site environments. Its compact size allows it to be mounted on a test bench, carried in a tool bag, or integrated into a custom test rig.
