GE IS200TSVOH2B 伺服控制板的操作：LVDT 位置反馈、LVDT 激励、双向伺服电流输出和脉冲率流量输入均包含在 VSVO 的四个通道中。TSVO 最多可以提供六个 LVDT 阀位输入的激励，TSVO 也接受来自这些输入的输入。对于每个伺服控制环路，可以选择一个、两个、三个或四个 LVDT。对于测量燃气轮机流量的应用，提供了三个输入。这些信号通过 TSVO 并直接发送到 VSVO 板正面的 J5。断电时，每个伺服输出都有一个专用自杀继电器，在由固件控制时，会将 VSVO 输出信号短接到公共信号，然后根据手动复位指令返回正常操作。每个伺服系统的输出电压、电流和自杀继电器均通过诊断进行监控。

The operation of the GE IS200TSVOH2B servo control board includes LVDT position feedback, LVDT excitation, bidirectional servo current output, and pulse rate flow input in the four channels of the VSVO. TSVO can provide excitation for up to six LVDT valve position inputs, and TSVO also accepts inputs from these inputs. For each servo control loop, one, two, three, or four LVDTs can be selected. For the application of measuring gas turbine flow, three inputs are provided. These signals are sent directly to J5 on the front of the VSVO board through the TSVO. When power is off, each servo output has a dedicated suicide relay that, when controlled by firmware, shortens the VSVO output signal to a common signal and returns to normal operation according to a manual reset command. The output voltage, current, and suicide relay of each servo system are monitored through diagnosis.

IS200TSVOH2B is a servo control board manufactured by General Electric and is part of the Mark VI series used in gas turbine control systems. The four electro-hydraulic servo valves that operate the steam/fuel valve are guided by the servo control board. Usually, two servo terminal boards are used to separate these four channels (TSVO or DSVO). Use a linear variable differential transformer to determine valve position (LVDT). Execute loop control algorithm. Connect three cables to the J5 plug on the front panel and the J3/J4 connector on the VME rack. The JR1 connector is used for TSVO to provide simplex signals, while the JR1, JS1, and JT1 connectors are used for fanout TMR signals. Insert the external trip of the protection module into JD1 or JD2.

PLC内的I/O模板，除一般的DI/DO、AD/DA模板外，还发展了一系列特殊功能的I/O模板，这为PLC用于各行各业打开了出路，如用于条形码识别的ASCII/BASIC模板，用于反馈控制的PID模板，用于运行控制、机械加工的高速计数模板、单轴位置控制模板、双轴位置控制模板、凸轮定位器模板、射频识别接口模板等，这在以后还会有很大发展。另外在输入、输出的相关元件、强干扰场合的输入、输出电隔离、地隔离等方面也会更加完善。
