Current signal generators and signal source manufacturers are widely used in industrial settings for debugging PLCs and process instruments. They offer simple operation, long standby time, compact size, lightweight design, and high precision. The device is charged via a T-type USB port, allowing it to be powered by a mobile phone or computer. It features two output modes: one for current and voltage signals, and another for sensor simulation. Each output has dual functionality, making it versatile for various applications.
Key features of the current signal generator include:
First, it supports sensor analog output, simulating 4~20mA two-wire power distribution commonly found in devices like pressure transmitters. The positive and negative terminals of the device mimic those of a two-wire sensor, making it ideal for testing and calibration.
Second, it offers a passive output function that can act as a 0~24mA input, providing flexibility in different system configurations. The input and output ranges can be easily set and displayed, such as mapping 0~50 to 4~20mA for better visibility and control.
Technical specifications of the signal generator include:
Active current output: 0~24mA with a resolution of 0.01mA. The maximum load is 500 ohms (750 ohms is possible but may reduce battery life, so 500 ohms is recommended for most applications). Passive current output also provides 0~24mA with the same resolution, and can operate with a maximum negative supply voltage of 25V. It can also function as a current input.
The device also includes a 0~11V voltage output with a resolution of 0.01V. The overall accuracy is ±0.01%.
It is powered by a single 3.7V lithium battery, offering approximately 10 hours of continuous use at 20mA. The operating temperature range is from -10°C to 50°C, ensuring reliable performance in various environments.
The device uses a USB port for both power and charging, making it convenient and portable. The display backlight is white, enhancing readability in low-light conditions.
Whether you're working on industrial automation, process control, or field instrumentation, this signal generator is a powerful and flexible tool designed for efficiency, accuracy, and ease of use in real-world applications.
