关于 1794-IE12

Allen-Bradley 1794-IE12 是 Flex I/O 产品系列中的高密度模拟输入模块。

该模块主要用于连接模拟设备，如变送器、指示器、记录仪、单回路和多回路控制器以及其他设备。

1794-IE12 配有十二 （12） 个模拟输入通道，可配置为 0 至 20mA、4 至 20 mA、+/- 10VDC 和 0 至 10 VDC 输入信号类型。

模拟数据格式存储在16位左对齐寄存器中，所有通道的转换速率为8.0 ms。

对于电压和电流输入，1794-IE12 的绝 对精度为 0.1% 满量程 @ 25 °C，精度漂移为 0.004% 满量程/°C。

1794-IE12 设计用于 1794-TB3G 和 1794-TB3GS 终端底座。

每个模块只需要一个端子底座。将模块安装到适当的端子底座时，预期的钥匙开关位置为 3。

钥匙开关位置是一个万无一失的硬件安装钥匙，可防止将不正确的模块安装到错误的端子底座上。

1794-IE12 在标称电压为 24VDC 时工作，可接受的电源电压范围为 10 至 31.2 VDC。

它的物理尺寸为 3.7 x 3.7 x 2.1 英寸。模块的状态通过发光二极管（LED）绿色/红色电源/状态指示灯分组报告。

1794-IE12 具有开放式外壳。此模拟输入模块的兼容端子基座为 1794-TB3GS 和 1794-TB3G。

It has twelve (12) voltage/current single-ended input channels.

It is compatible with the Flex I/O communication adapter and is mounted on terminal mounts such as the 1794-TB3G or 1794-TB3GS.

About 1794-IE12

The Allen-Bradley 1794-IE12 is a high-density analog input module in the Flex I/O product family.

The module is mainly used to connect analog devices such as transmitters, indicators, recorders, single loop and multi-loop controllers, and other devices.

The 1794-IE12 features twelve (12) analog input channels that can be configured for 0 to 20mA, 4 to 20mA, +/- 10VDC, and 0 to 10VDC input signal types.

The analog data format is stored in a 16-bit left-justified register with a conversion rate of 8.0 ms across all channels.

For voltage and current inputs, the 1794-IE12 has an absolute accuracy of 0.1% full scale @ 25 °C and an accuracy drift of 0.004% full scale /°C.

The 1794-IE12 is designed for the 1794-TB3G and 1794-TB3GS terminal mounts.

Only one terminal base is required for each module. When the module is installed to the appropriate terminal base, the expected key switch position is 3.

The key switch position is a foolproof hardware installation key that prevents incorrect module installation to the wrong terminal base.

The 1794-IE12 operates at a nominal voltage of 24VDC, with an acceptable supply voltage range of 10 to 31.2 VDC.

Its physical dimensions are 3.7 x 3.7 x 2.1 inches. The status of the module is reported in groups with light emitting diode (LED) green/red power/status indicators.

1794-IE12 has an open housing. Compatible terminal bases for this analog input module are 1794-TB3GS and 1794-TB3G.
