Product introduction:
ISO AD series converter achieve the signal isolated acquisition between sensor and the host and can be used for a variety of sensors. ISO AD series A-D Converter can be used in industrial automation RS-232/485 bus system, 4-20mA / 0-5V signal measurement, monitoring and control, small-signal measurement, and industrial-site signal isolation and long-term transmission and so on.
The A-D Converters 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 A-D Converters are based on the 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.
The power supply and communication interface are isolated, it can withstand 3000VDC isolation voltage, anti-interference ability, high reliability.
Operating temperature range: - 45 ~ +80º C
