General Description:
JSD81 series products realize the signal acquisition between sensor and host, to measure analog signals. JSD81 products can be applied to RS-232/485 bus industrial automation control system,4-20mA/0-5V signal measurement, monitoring and control,0-75mV ,0-100mV and other small-signal measurement and signal 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 JSD81 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
JSD81 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.JSD81 products are according to industry standard design, isolation between signal input / output, can withstand voltage 3000VDC, high anti-interference ability and reliability. Operating temperature range is - 45 ~ +85 °C.
