SunYuan SY series AD products (Adam module) can realize safe signal isolation and high-precision data acquisition, isolation conversion, monitoring and transmission between sensor and host. The products are widely used in RS-232/485 bus industrial automation control system, 4-20mA / 0-10V analog detection, monitoring and control, small signal measurement and industrial field sensor signal isolation transmission and other remote monitoring occasions. Through the configuration of the software, it can be accessed to a variety of sensor types, including current output type, voltage output type and so on.

      The product internally includes modules for power isolation, signal isolation, linearization, A/D conversion and RS-485 serial communication. Each serial port can be connected to a maximum of 256 SY AD series modules, the communication method adopts ASCII code character communication protocol or MODBUS RTU communication protocol, and its instruction set is compatible with ADAM module, the baud rate can be set by the user, and it can be hooked up with the control modules of other manufacturers on the same RS-485 bus, which is convenient for programming by the host.

     SY series AD products are intelligent monitoring and control system based on microcontroller, all the configuration information such as calibration value, address, baud rate, data format, calibration and status set by the user are stored in non-volatile memory EEPROM.

       SY series AD products are designed and manufactured according to industrial standards, signal input/output isolation, can withstand 3000VDC isolation voltage, strong anti-interference ability, high reliability. Operating temperature range - 45℃～+80℃.

Multi-channel Analog Signal Acquisition Control Isolation Transmitter Function Introduction

SYAD02/4A signal isolation acquisition module can be used to measure two (or four) current or voltage signals that can be common ground and will not interfere with each other. Analog signal input: 24-bit acquisition accuracy, all signal input ranges have been fully calibrated before the product leaves the factory. In use, the user can also easily program their own calibration. For specific current or voltage input ranges, please refer to the product selection, and when measuring two signals, both input selections must be the same.
