monitor equipment operation Sensor Signal measurement industrial data acquisition and recording medical, Industrial Product Development 4-20mA signal acquisition Product Overview: ISOAD A08 achieve Sensor And between the host signal acquisition, to detect the analog signal or control a remote device. Passive isolation using advanced technology to achieve mutual isolation between each channel, so that the family greatly improved anti-jamming, in industrial applications more convenient. RS-232/485 bus products can be used in industrial automation control systems ,4-20mA signal acquisition and so on. Products include power supply isolation, signal isolation per channel, A / D converter and RS-485 serial Communicate . Each serial port can access up to 255 ISOADA08 series of modules, supports two communication protocols, the command set of characters defined protocol and MODBUSRTU communication protocols, its instruction set compatible with the ADAM modules, the baud rate set by the code, can control other manufacturers module linked to the same RS-485 bus, the convenience of computer programming.
ISOADA08 is based of an intelligent monitoring and control system, all users set the calibration value, address, baud rate, check and status, communication protocols, channel status, and configuration information are stored in non-trade volatile EEPROM memory inside.
ISOAD A08 series products according to industry standard design, manufacture, each signal input channel / output / auxiliary power supply isolation between, can withstand 3000VDC isolation voltage, anti-interference ability, high reliability. Operating temperature range -45 ~ +80 .

ISOAD A08 Features: ISOAD A08 8 way signal isolation acquisition module, used to measure the 4-20mA/0-20mA current signal.
1, analog signal input 8 channel 4-20mA signal input, mutual isolation between each channel, the product of all signals have been factory calibrated. In use, the user can easily program their own calibration.
2, the communication protocol Communication Interface: 1 channel standard RS-485 communication interface or a road standard RS-232 communication interface, when the state order selection.
Protocol: support two protocols, the command set of characters defined protocol and MODBUS RTU communication protocol. Can be programmed using the communication protocol that can be achieved with multiple brands of PLC, RTU or computer monitoring system for network communication.
Data format: 10. A start bit, 8 data bits, 1 stop bit. Mailing address (0 ~ 255) and the baud rate (300,600,1200,2400,4800,9600,19200,38400 bps) can be set; the most long-distance communications network up to 1200 meters, through the twisted-pair shielded cable. Communication interface with high anti-interference design, ± 15KV ESD protection, communications, response time is less than 100mS.
3, interference may be necessary to set the checksum. Module internal transient suppression diodes, can inhibit a variety of surge pulse protection module, the internal digital filter can also be very good suppression frequency interference from the power grid.
