IS200TPROH1C是GE開(kāi)發(fā)的緊急保護(hù)（TPRO）終端板。三個(gè) PPRO I/O 包安裝在緊急保護(hù) （TPRO） 端子板上。它具有一對(duì)用于總線和發(fā)電機(jī)電壓輸入的電位變壓器 （PT），并為 PPRO 調(diào)節(jié)速度信號(hào)輸入。上面有三個(gè) DC-37 針連接器，PPRO 組連接器的每一側(cè)一個(gè)。每個(gè) DC-37 都接受通向 Mark* VIe 后備跳閘繼電器端子板的電纜。TPROH1C 有兩個(gè)可插拔模塊，每個(gè)模塊有 24 個(gè)屏障端子。

不要無(wú)意中交叉連接 240 V 交流和 240 V 交流應(yīng)用中的直流電壓。峰值電壓將高于 MOV 額定值，導(dǎo)致 MOV 失效。大多數(shù)交流電源具有接地零線，因此，如果在 125 V 直流和交流電壓之間建立意外連接，則交流峰值電壓和 125 V 直流之和將應(yīng)用于直流和接地之間連接的 MOV。另一方面，在 120 V 交流應(yīng)用中，MOV 額定值可以承受峰值電壓而不會(huì)失效。

IS200TPROH1C 兼容性
TPROH1C 是一個(gè)單工和 TMR 應(yīng)用程序，可與 PPRO I/O 包配合使用。TPROH#C 鏈接到 TMR 系統(tǒng)中的三個(gè) PPRO I/O 包。TPROH1CD 和 H12C 都接受三個(gè) PPROH1A 用于直接連接，并包括用于三根電纜到備用跳閘繼電器端子板的 DC-37 連接。

IS200TPROH1C 安裝
TPROH1C 和塑料絕緣體安裝在安裝在 DIN 導(dǎo)軌安裝的鈑金載體上。TPRO 和絕緣體也可以安裝在直接用螺栓固定在面板上的鈑金組件上。典型的 #18 AWG 電線用于將速度信號(hào)和 PT 輸入連接到接線端子?？梢圆鹣?TPROH1C 阻隔接線端子以更換電路板。TPROH2C 是一種可插入的可拆卸歐式接線端子。

IS200TPROH1C 操作

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.
