SY AD Series Low Cost Multi-Channels Analog Signal to RS232/485 A/D Converters
SYAD02/04A A-D Converters 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), SYAD02/04A 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 may be associated with up to 256 PCS SYAD02/04A series modules. The communication methods use ASCII character communication protocol or MODBUS RTU 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. SY series 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.
SY series products are designed and manufactured according to industry standard. The signal output and communication interface are isolated, it can withstand 3000VDC isolation voltage and with anti-interference ability, high reliability. Operating temperature range: - 45 to +80 degree
