IS200VRTDH1D是Mark VI系统创建的PCB（印刷电路板）组件，也被称为电阻温度设备输入板。该板设计用于接受16个三线RTD输入，这些输入连接到RTD终端板，而不是直接连接到板，然后通过电缆连接到安装它的VME机架。
此外，IS200VRTDH1D具有一个面板，上面安装了三个LED指示灯，用于指示运行、故障和状态。这些LED灯有绿色、红色和橙色三种颜色。面板通过三个螺丝连接到主PCB上。
在电路板上，可以看到大量的电容器（超过200个）、电阻（数百个）和集成电路（超过200个），其中还包括现场可编程门阵列（FPGA）。此外，板上还装有两个背板连接器。
从功能上看，IS200VRTDH1D适用于紧凑型PLC不能应用的地方，因为它提供了多达30个I/O，并能通过串行通信传输数据。此外，它还具有定位和脉冲输出功能，可以同时输出2点100KHz脉冲，并配备有7条特殊的定位指令。
The IS200VRTDH1D is a PCB (printed circuit board) component created by the Mark VI system, also known as the Resistance temperature device input board. The board is designed to accept 16 three-wire RTD inputs that are connected to the RTD terminal board, rather than directly to the board, and then connected via cable to the VME rack where it is mounted.
In addition, the IS200VRTDH1D has a panel mounted with three LED indicators to indicate operation, failure and status. The leds come in green, red and orange. The panel is attached to the main PCB by three screws.
On the circuit board, you can see a large number of capacitors (more than 200), resistors (hundreds) and integrated circuits (more than 200), which also includes field programmable gate arrays (FPgas). In addition, the board is equipped with two backplane connectors.
Functionally, the IS200VRTDH1D is suitable where compact PLCS cannot be applied, as it provides up to 30 I/ OS and is capable of transmitting data via serial communication. In addition, it also has positioning and pulse output functions, can output 2 point 100KHz pulses at the same time, and is equipped with 7 special positioning instructions.
