Remote Rs232 Data Acquisition With Temperature Detection For Signal Testing / Monitoring / Control

Sunyuan SY AD series achieve the signal acquisition between sensor and the host to test analog signal or control remote device. The configuration software can be used for a variety of sensors including analog input, analog output, and digital signal input / output (I / O), ISO SYAD series of products can be used in industrial automation RS-232/485 bus system,4-20mA / 0-10V signal measurement, monitoring and control, small-signal measurement, and industrial-site signal isolation and long-term transmission and so on.

Products include power supply isolation, signal isolation, linearization, A/D conversion and RS-485 serial communication. Each serial port of the maximum 256 ISO SYAD series of modules, means of communication using ASCII character communication protocol or MODBUS RTU communication protocol communication protocol, its instruction set compatible with the ADAM modules, the baud rate is set by the user, with other manufacturers control module hanging in the same RS-485 bus, to facilitate computer programming.

SYAD series of products are based on single chip of intelligent monitoring and control systems, all the user to set the calibration value, address, baud rate, data format, checksum status and other configuration information is stored in nonvolatile memory EEPROM inside.

SYAD series of products according to industry standard design, manufacture, signal output / communication interface isolation, can withstand 3000VDC isolation voltage, anti-interference ability, high reliability. Operating temperature range: - 45℃ ~ +80℃.

   U7:0-±100mV    A7:0-±20mA

   U8:Customized   A8:Customized

Note:SY AD 02C can support RS232 and RS485 communication port, user can choose the communication port according the application environment. But at the same time, only one communication port can work, or will have interference.

E.g.:

1, SY AD 02C A4 Means 4-20ma signal output, and support one channel DS18B20 temperature signal input

2, SY AD 02C A7 Means 0-5V signal output,  and support one channel DS18B20 temperature signal input

3, SY AD 02C U1   Means 0-±5V signal output, and support one channel DS18B20 temperature signal input

Note:SYAD02C module supports both RS232 and RS485 communication interface, the user can select the corresponding communication interface based on the use of the environment, but at the same time can have only one of the two interfaces work, or will cause interference.

E.g.

1: SYAD02B-A4      Two channel 4-20ma signal output

2: SYAD04B- A7      Four channel 0-±20mA signal output

3: SYAD02B- U1      Two Channel 0-5V signal output
