Analog Signal to Digital Signal RS232/485 Output A/D Data Acquisition Converters
Introduction: ISO 4021 series analog to digital converter realizes the signal acquisition between sensor and the host to test analog signal or control remote device.The configuration software can be used for a variety of sensors including analog input, analog output, and digital signal input / output (I / O), ISO 4021 series products can be used in industrial automation RS-232/485 bus system4-20mA / 0-5V signal measurement,monitoring and control, small-signal measurement, and industrial-site signal isolation and long-term transmission and so on. Through software configurationit can be connected various sensors including current output type,voltage output type and thermocouple etc.
The converters has the following features: power supply isolationsignal isolation linearization,A/D conversion and RS-485 serial communication. Each serial port can connect maximum is 256 pieces ISO 4021 modules. The method of communication used is character communication protocol ASClI or MODBUS RTU communication protocol, its command set is compatible with the ADAM modules, the baud rate is set by the user, it is able to operate in the same RS-485 bus with controlling module from other manufacturers to facilitate computer programming.
ISODA series converters are designed based on single chip of intelligent monitoring and control systems, all the calibration value,address,baud ratedata formatchecksum status and other configuration information set by users are stored in nonvolatile memory EEPROM.
ISODA series converters are in accordance with industry standards in design, manufacturing, isolation voltage between signal I/O is 3000VDC,it possesses excellent anti interference ability and high reliability. Operating temperature range:-25 to +70 degree.
Features: 1. Measurement accuracy is better than 0.05%. 2. Automatically select RS-485 or 232 output,programmable calibration of modules accuracy is available. 3. Isolation voltage between I/O:3000VDC. 4. Wide power supply range: 8~50VDC 5. High reliability, convenient to programme, install and wire 6. User can set object module's address and baud rate and other parameters by programming. 7. Support Modbus RTU communication protocol. 8. Analog signal acquisition,isolated conversion, RS-485/232 output.
Application: 1. PLC,DCS Signal testing,monitoring and control. 2. Intelligent building control,security system etc. 3. RS-232/485 industrial automation control system. 4. Industrial fields signal isolation and long-distance transmission. 5. Debugging and controlling of equipment operation. 6. Sensors signal measurement and acquisition. 7. Acquisition and record of industrial field data. 8. Development of medical,electric and industrial products,etc. 9. 4-20mA/0-10V signal acquisition and transmission.
