IS200TPROS1CBB-IS230TSPRH1C-MRP680538 GE 紧急保护（TPRO）终端板

IS200TPROH1C是GE开发的紧急保护（TPRO）终端板。三个 PPRO I/O 包安装在紧急保护 （TPRO） 端子板上。它具有一对用于总线和发电机电压输入的电位变压器 （PT），并为 PPRO 调节速度信号输入。上面有三个 DC-37 针连接器，PPRO 组连接器的每一侧一个。每个 DC-37 都接受通向 Mark* VIe 后备跳闸继电器端子板的电缆。TPROH1C 有两个可插拔模块，每个模块有 24 个屏障端子。

不要无意中交叉连接 240 V 交流和 240 V 交流应用中的直流电压。峰值电压将高于 MOV 额定值，导致 MOV 失效。大多数交流电源具有接地零线，因此，如果在 125 V 直流和交流电压之间建立意外连接，则交流峰值电压和 125 V 直流之和将应用于直流和接地之间连接的 MOV。另一方面，在 120 V 交流应用中，MOV 额定值可以承受峰值电压而不会失效。

IS200TPROH1C 兼容性
TPROH1C 是一个单工和 TMR 应用程序，可与 PPRO I/O 包配合使用。TPROH#C 链接到 TMR 系统中的三个 PPRO I/O 包。TPROH1CD 和 H12C 都接受三个 PPROH1A 用于直接连接，并包括用于三根电缆到备用跳闸继电器端子板的 DC-37 连接。

IS200TPROH1C 安装
TPROH1C 和塑料绝缘体安装在安装在 DIN 导轨安装的钣金载体上。TPRO 和绝缘体也可以安装在直接用螺栓固定在面板上的钣金组件上。典型的 #18 AWG 电线用于将速度信号和 PT 输入连接到接线端子。可以拆下 TPROH1C 阻隔接线端子以更换电路板。TPROH2C 是一种可插入的可拆卸欧式接线端子。

IS200TPROH1C 操作
在 31-48 号航站楼上，显示九速输入。消费者可以从 24、5 和 9 号航站楼获得 P11 输出。P24 输出的返回路径是端子 8 （MARET）。I/O 组 R、S 和 T 的 28 V 电源产生 P24 输出。即使任何 I/O 包关闭，也可以访问 P24 V 输出。端子 6、10 和 12 是 4-20 mA 输入，扇形连接到 R、S 和 T PPRO 连接，并分配给将来的控制扩展。对于 4-20 mA 输入，端子 8 （MARET） 用作返回路径。

The IS200TPROH1C is an Emergency Protection (TPRO) terminal board developed by GE. Three PPRO I/O packages are installed on the Emergency Protection (TPRO) terminal board. It has a pair of potential transformers (PT) for the bus and generator voltage input and regulates the speed signal input for the PPRO. There are three DC-37-pin connectors on it, one on each side of the PPRO group connector. Each DC-37 accepts a cable to the Mark* VIe backup trip relay terminal board. TPROH1C has two pluggable modules, each with 24 barrier terminals.

Do not unintentionally cross-connect the DC voltage in 240 V AC and 240 V AC applications. The peak voltage will be higher than the MOV rating, resulting in MOV failure. Most AC power supplies have ground neutral wires, so if an accidental connection is established between 125 V DC and AC voltage, the sum of the peak AC voltage and 125 V DC will be applied to the MOV connected between DC and ground. On the other hand, in 120 V AC applications, MOV ratings can withstand peak voltages without failure.

IS200TPROH1C Compatibility
TPROH1C is a simplex and TMR application that works with PPRO I/O packages. TPROH#C links to the three PPRO I/O packages in the TMR system. Both the TPROH1CD and H12C accept three PPROH1As for direct connections and include a DC-37 connection for the three cables to the spare trip relay terminal board.

IS200TPROH1C Installation
The TPROH1C and plastic insulators are mounted on a sheet metal carrier mounted on a DIN rail mount. TPRO and insulators can also be mounted on sheet metal assemblies bolted directly to the panel. A typical #18 AWG wire is used to connect the speed signal and PT input to the terminal. The TPROH1C block terminal can be removed to replace the circuit board. TPROH2C is a removable European terminal that can be inserted.

IS200TPROH1C operation
On Terminal 31-48, a nine-speed input is displayed. Consumers can get P11 output from Terminals 24, 5 and 9. The return path of the P24 output is Terminal 8 (MARET). 28 V power supplies for I/O groups R, S, and T produce P24 outputs. P24V output can be accessed even if any I/O packets are closed. Terminals 6, 10, and 12 are 4-20 mA inputs, fanned to R, S, and T PPRO connections, and assigned for future control extensions. For 4-20 mA inputs, terminal 8 (MARET) is used as the return path.
