D/A converter General Description:
JSD DA-A02 series realize host RS-485/232 interface signal isolation converted into a standard analog signal, to control the remote device. JSD DA-A02 products can be applied to RS-232/485 bus industrial automation control system,4-20mA /0-5V/0-10V standard signal output, to control industrial site execution set equipment, control equipment and display instrument. Products include power supply isolation, signal isolation, linearization, D/A conversion and RS-485 serial communication. Each serial interface can connect up to 256 pieces JSD DA-A02 Series modules, communication using ASCII code or MODBUS RTU communication protocol, and its instruction set compatible with the ADAM modules, baud rate can been set by the code, with other manufacturers control module hang in the same RS-485 bus for easy programming.
JSD DA-A02 series products are based on SCM's intelligent monitoring and control system, users set the calibration value, address, baud rate, data format, checksum status, and configuration information are all stored in nonvolatile memory EEPROM.
JSD DA-A02 products are according to industry standard design, isolation between signal output / communication interface, can withstand voltage 3000VDC, high anti-interference ability and reliability. Operating temperature range is - 45 ~ +85°C.
