Tianxing Zhilian CDL-8DA conversion module RS485 to voltage and current analog signal product introduction

          The TS CDL-8DA module is a suitable product for use in industrial environments, which can realize the isolation of the host RS485 or 232 interface signal into standard analog signals

(At the same time, it can collect switching signals), to control remote equipment, this module can be applied to RS485, RS232 bus bus industrial automation control system, will be computer

The serial communication signal is converted into a standard analog signal output of 4-20mA or 0-5V, which is used to control the execution equipment, instrumentation, PLC/DCS/FCS/PCC/etc.

The CDL-8DA module includes power isolation, signal isolation, DA conversion, RS485 serial communication and more configuration; The serial port communication mode adopts Modbus communication protocol, which can be set

The wave rate can be hung on the same RS485 bus with the control module of other manufacturers, which is convenient for computer programming. This product is based on the intelligent monitoring and control system of single-chip microcomputer

All user-defined calibration values, addresses, baud rates, data formats, checksum status, and other configuration information can be stored.

Advantages of Tianxing Zhilian CDL-8DA conversion module RS485 to voltage and current analog signal products

          The shell integrates a rail interface for easy industrial field installation, which can convert 8 current analog outputs at the same time, and can also collect data on the switching quantity at the same time

Adopt industrial integrated design, special design in temperature range, vibration, electromagnetic compatibility and interface diversity, etc., to ensure the stability of work in harsh environments.

It provides a reliable guarantee for the accuracy and stability of the data.

Tianxing Zhilian CDL-8DA conversion module RS485 to voltage and current analog signal product features

◆ Strong anti-interference ability

           ◆ The output signal is linear

           ◆ -45°C~+85°C working range

           ◆ High reliability: Simple to set up and easy to install

           ◆ The voltage isolation between the signal output and the communication interface can withstand 3000VDC

Tianxing Zhilian CDL-8DA conversion module RS485 to voltage and current analog signal product function

             Communication protocol: standard modbus protocol

Communication interface: 1 standard RS485 communication interface optional RS232 interface

Communication interface: High anti-interference design: ±15KV ESD protection, communication response time< 100ms

Analog signal: 8 signal outputs, all signal output ranges are calibrated before the product leaves the factory. It can also be easily calibrated by the user when in use

Anti-interference: There is a transient suppression diode inside the module, which effectively suppresses the surge pulse, protects the digital inside the module and also suppresses the power frequency interference from the power grid
