Aposun CHDS4A Series Universal Input Digital Panel Meter

Product Information

The CHDS4A series Universal Input Digital Panel Meter is a versatile instrument that can accept various types of signals including 4-20mA, 0-10V, 0-75mV, TC/RTD, and load cell. It is widely used in different applications such as temperature, pressure, weighting, resistance, current, and voltage measurement. This digital panel meter also provides 20-stage programmable settings for non-linear input. The input, output, and power supply are isolated from each other which ensures safety and accuracy in measurements. The instrument has a model number CHDS4A and comes in a standard size of 48W*48H mm. It features a universal input type with default input options of 4-20mA, 0-10V, and 0-75mV. The user can choose other input options by specifying them during ordering. The instrument has two options for aux power supply, 12V DC or 24V DC. There are three options for the alarm function – relay, solid state (SS), or none. The instrument also has an analog output function that can be chosen along with the alarm function.

Product Usage

Before using the CHDS4A series Universal Input Digital Panel Meter, it is essential to read the user manual carefully to understand its  features and functions. Here are the steps to use the instrument:

1. Connect the power supply according to the specifications mentioned in the manual.
2. Select the input type that matches your signal source.
3. If your signal is non-linear, set up the 20-stage programmable settings as per your requirement.
4. Select the analog output or alarm function that suits your application.
5. Once all functions are set up correctly, start measuring the signal.

It is important to note that the input, output, and power supply are isolated from each other, ensuring safety and accuracy in measurements. If you face any issues or have any questions about the instrument’s usage, please refer to the user manual or contact the manufacturer for assistance.

First of all, thank you for using our qualified products. Please read this manual carefully before use so that you can fully understand and properly use the instrument
