L-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 circuit module. Each serial port can connect maximum 256 pcs of isoad series modules, means of communication using 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 host programming.
Iso ad series of products are based on single chip of intelligent monitoring and control systems, all the user sets such as the calibration value, address, baud rate, data format, checksum status and other configuration information is stored in nonvolatile memory eeprom inside.
Isoda series of products according to industry standard design, manufacture, signal output / communication interface isolation, can withstand 3000vdc isolation voltage, anti-interference ability, high reliability. Operating temperature range: - 45 ~ +80.
