High Precision Thermocouple Signal Isolated RS232 Data Acquisition Module With Multi-Range

High Precision Thermocouple Signal Isolated RS232 Data Acquisition Module with Multi-Range

SY AD 08TSeries products achieve the signal data acquisition between sensor and host which are used to measure analog signal or control remote equipments. And through the configuration of software, they can be used in various types of sensors including: analog signal input, analog signal output and digital signal input and output.SY AD 08T Series products can also be used in industrial automation RS232/485-bus system, thermocouple signal measurement, monitoring and control, small signal measurement and industrial-site signal isolation and long-term transmission.

The products include power supply isolation, signal isolation between input and output, A/D conversion and RS485 series communication circuit module. Each port can connect maximum 256 pieces of SYAD08T series modules, and adopts ASCII character communication protocol or MODBUS RTU communication protocol in communication whose instructions set compatible with ADAM module, the baud rate set by user. And the product can hang in the same RS-485 bus with control model from other manufactures to facilitate host programming.

SYAD08T Series products are the intelligent monitoring and control system based on MCU. All the configuration information set by user includes calibration value, address, baud rate, data format, calibration and status are all deposit in nonvolatile storage device--EEPROM.

SYAD08T Series products can be used to measure varies models of sensor signal  includes thermocouple, thermal resistance, strain gauge and others, the specific model selection should be done by reference to the model code supported by different models of  products.

SYAD08T Series products are designed on the industrial standard, there is isolation between input and output, the isolation is 3000VDC, high reliability and strong resistance to interference. Industrial operating temperature:  - 45℃～+85℃

Applications:

● Application in medical, industrial products development

Specifications:

● Support MODBUS RTU communication protocol

Thermocouple Types

J: J type          R: R type

K: K type         S: S type

        T: T type         B: B type

        E: E type

Remarks:

① The model selection of SYAD08T series is just initial type of thermocouple which supports by the module. User can change the types of thermocouple by re-configurating the module through ASCII character command, then calibrate it.

② SYAD08T series modules support both RS232 and RS485 communication interface. User can choose the communication interface according to the application environment, and at the same time only one interface works, otherwise it may interference with each other.
