870ITEC-AYFNZ-7   智能变送器   基于PC的配置器

870ITEC-AYFNZ-7

870ITEC-AYFNZ-7智能变送器将无电极电导率测量值转换为4至20mA和/或数字输出信号，具体取决于所选择的型号和实施的配置。

870ITEC-AYFNZ-7仅模拟输出版本(型号870ITEC-A)支持在前面板本地进行配置、校准和故障诊断。该变送器有一个4至20 mA直流输出，可通过软件配置(连接)到温度补偿测量、未补偿(绝对)测量或温度。

870ITEC-AYFNZ-7数字输出版本(型号870ITEC-F)支持通过信号线上任何位置的基于PC的配置器，或通过智能变送器现场总线模块从任何I/A系列工作站，在前面板本地进行配置、校准和故障诊断。数字输出版本支持纯数字通信或配置的4至20mA直流/数字混合通信。在这两种模式下工作时，变送器连续输出三个数字测量值:温度补偿测量值、未补偿(绝对)测量值和温度。在4到20mA模式下，您可以将输出分配给三个测量参数中的任何一个。

规格

传感器:

870ITEC-AYFNZ-7变送器可与任何871EC系列无电极电导率传感器或871FT系列流通式传感器一起使用。通过在配置过程中输入电池因子，它们也可以与其他电气兼容的传感器一起使用。

1000欧姆铂RTD

100千欧姆热敏电阻器

环境温度:-25至+55摄氏度

相对湿度:0至95%不凝结

电磁兼容性(EMC):当传感器电缆和I/0电缆封闭在刚性金属导管中时870ITEC型智能变送器符合欧洲EMC指令89/336/EEC的要求。

电源要求(4至20 mA输出):12.5至42V直流电压

你的870IT是2线制变送器。同样地，它通过接收功率的相同的两根线传输输出。如果您的发射机指定为模拟通信(870ITEC-A)，则必须为其提供电源。如果指定为数字通信(870ITEC-F)，则可通过I/A系列现场总线模块提供电源。将此电源/输出信号连接到电源端子，并将测量传感器的信号连接到外壳顶部附近的相应端子，如图1所示。

870ITEC-AYFNZ-7

The 870ITEC-AYFNZ-7 smart transmitter converts electrodeless conductivity measurements to 4 to 20mA and/or a digital output signal, depending on the model chosen and the configuration implemented.

The 870ITEC-AYFNZ-7 Analog output only version (Model 870ITEC-A) supports local configuration, calibration, and fault diagnosis on the front panel. The transmitter has a 4 to 20 mA DC output that can be configured (connected) by software to temperature compensated measurement, uncompensated (absolute) measurement, or temperature.

The 870ITEC-AYFNZ-7 Digital Output version (Model 870ITEC-F) supports configuration, calibration and fault diagnosis locally on the front panel from A PC-based configurator anywhere on the signal line, or from any I/A series workstation via the smart transmitter Fieldbus module. The digital output version supports pure digital communication or configured 4 to 20mA DC/digital hybrid communication. When operating in both modes, the transmitter continuously outputs three digital measurements: temperature compensated measurement, uncompensated (absolute) measurement, and temperature. In 4 to 20mA mode, you can assign the output to any of the three measurement parameters.

specification

Sensor:

The 870ITEC-AYFNZ-7 transmitter can be used with any 871EC series electrodeless conductivity sensor or 871FT series flow-type sensor. By inputting a battery factor during configuration, they can also be used with other electrically compatible sensors.

Maximum distance between sensor and transmitter :30.5 m (100 ft) Temperature compensation Input:

100 ohplatin RTD

1000 ohplatin RTD

100 kiloohms thermistor

Ambient temperature :-25 to +55 degrees Celsius

Relative humidity :0 to 95% non-condensing

Electromagnetic Compatibility (EMC): When the sensor cable and I/0 cable are enclosed in a rigid metal conduit, the 870ITEC smart transmitter complies with the requirements of the European EMC Directive 89/336/EEC.

Power requirements (4 to 20 mA output):12.5 to 42V DC voltage

Your 870IT is a 2-wire transmitter. Similarly, it transmits the output through the same two wires that receive the power. If your transmitter is designated for analog communication (870ITEC-A), it must be powered. If specified for digital communication (870ITEC-F), power can be supplied via the I/A series fieldbus module. Connect this power/output signal to the power terminal and connect the signal of the measurement sensor to the corresponding terminal near the top of the housing, as shown in Figure 1.
