current/voltage signal to RS485/RS232 A/D converter General Description:
JSD AD11 series products realize the signal acquisition between sensor and host, to measure analog signals. JSD AD11 series products can be applied to RS-232/485 bus industrial automation control system, 4-20mA / 0-5V signal measurement, monitoring and controlling, 0-75mV, 0-100mV and other small-signals measurement and signals isolation and long-term industrial transmission and so on. Products include power supply isolation, signal isolation, linearization, A/D conversion and RS-485 serial communication. Each serial interface can connect up to 255 pieces JSD AD11 Series modules, communication using ASCII code or MODBUS RTU communication protocol, and its instruction set compatible with the ADAM modules, baud rate can be set by the code, with other manufacturers control module hang in the same RS-485 bus for easy programming
JSD AD11 series is based on SCM intelligent monitoring and control system, all of the users set configuration information such as Calibration value, address, baud rate, data format, checksum and status are stored in non-volatile memory EEPROM.
JSD AD11 series products according to industry standard design and manufacture .They are three-port isolation(input, output and power supply),and the isolation voltage between them is up to 3000 VDC, JSD AD11 series products have better Anti-interference ability, high reliability and wide operating Temperature Range (- 45℃～+85℃.)
