Rs485 / Rs232 Data Acquisition Conversion With 8-Channel, 4-20ma Isolated Signal Acquisition Module

8-Channel Analog Signal Isolated Converter, High Precision Remote Rs232 Data Acquisition Module

SYAD08Series 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. SYAD08 Series products can also be used in industrial automation RS232/485-bus system, 4-20mA/0-10Vsignal 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 SYAD08 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.

    SYAD08 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.

SYAD08 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.
