ABSOLUTE API4380-G是一种接受DC电压或电流输入，并提供光学隔离的DC电压或电流输出的变送器。
ABSOLUTE API4380-G具有以下特性：
1.线性化滤波，有源滤波除了运算放大器和晶体管等有源元件外，还使用无源元件。
2.数字滤波器是一种用来处理信号的数学滤波器，例如阻断或通过特定的频率。
3.输入和输出之间的光学隔离使得用于消除接地环路的模块，共模信号抑制和噪声拾取减少。
4.ABSOLUTE API4380-G电源被离，从而形成全3路（输入，输出，电源）隔离。5.输入和输出可通过以下方式进行现场配置外部旋转和滑动开关。
ABSOLUTE API4380-G使用详情如下：
常见的范围设置有在模块标签上，最常见的范围是内置的，可以从模块上的表格中选择，但是虚拟地无限的组合是可能的。
内置18VDC未调节回路励磁电源可用于为无源输入设备供电。

ABSOLUTE API4380-G has the following characteristics:
1. Linear filtering, active filtering uses passive components in addition to active components such as operational amplifiers and transistors.
2. A digital filter is a mathematical filter used to process signals, such as blocking or passing through specific frequencies.
3. The optical isolation between input and output enables modules used to eliminate ground loops, reduce common mode signal suppression, and reduce noise pickup.
4. The ABSOLUTE API4380-G power supply is disconnected, forming a complete 3-way (input, output, power supply) isolation.
5. The input and output can be configured on-site with external rotary and sliding switches through the following methods.
The usage details of ABSOLUTE API4380-G are as follows:
The ABSOLUTE API4380-G can accept DC voltage or current input and provide optically isolated DC voltage or current output in a linear relationship with the input.
The common range settings are on the module label, and the most common range is built-in, which can be selected from the table on the module, but virtual unlimited combinations are possible.
The built-in 18VDC unregulated circuit excitation power supply can be used to power passive input devices.
