>>>>>型号:IS220PPROH1A 涡轮机专用的 I/O 模块 提供直接接口
【功能描述】
IS220PPROH1A是涡轮机专用的 I/O 模块。它旨在为特定的涡轮机现场设备提供直接接口。这种设置消除或减少了以前连接到现场设备所需的大部分仪器，还提高了运行可靠性并减少了长期维护。该IS220PPROH1A通常与TREAH_A端子板配合使用，用于航改型涡轮机紧急跳闸应用。该组件可以连接到栅栏式或箱式接线端子。该IS220PPROH1A具有电压检测的现场接线限制，将电缆长度限制为 1,000 英尺的 18 AWG 接线。需要注意的是，将 BPPB P-Pack 与 BPPC P-Pack 交换时，无法自动重新配置IS220PPROH1A。
IS220PPROH1A内置一个前面板，上面标有组件 ID 号和几个 LED 指示灯。它们成对放置在前面板上。第一对标记为 PWR/ATTN，第二对标记为 LINK/TxRx 和 ENET 1，第三对标记为 LINK/TxRx 和 ENET2。最后一个组件位于面板底部;这被标记为 IR 端口。
IS220PPROH1A接受三个速度信号。 这包括减速、加速和超速。该组件还具有实现超速的硬件。该套件通过一组全面的反馈信号监控所选脱扣板的状态和运行。该套件支持 TMR 和单工备份保护。

【英文介绍】
The IS220PPROH1A is an I/O module for turbines. It is designed to provide a direct interface to specific turbine site equipment. This setup eliminates or reduces much of the instrumentation previously required to connect to field equipment, and also improves operational reliability and reduces long-term maintenance. The IS220PPROH1A is usually used in conjunction with the TREAH_A terminal board for emergency trip applications in aircraft modification turbines. The assembly can be connected to fence or box terminals. The IS220PPROH1A has field wiring limits for voltage detection, limiting cable length to 1,000 feet of 18 AWG wiring. Note that the IS220PPROH1A cannot be automatically reconfigured when swapping BPPB P-Pack with BPPC P-Pack.
The IS220PPROH1A has a built-in front panel marked with the component ID number and several LED indicators. They are placed in pairs on the front panel. The first pair is labeled PWR/ATTN, the second pair is labeled LINK/TxRx and ENET 1, and the third pair is labeled LINK/TxRx and ENET2. The last component is located at the bottom of the panel; This is labeled as an IR port.
The IS220PPROH1A accepts three speed signals. This includes deceleration, acceleration and speeding. The component also has hardware to enable overspeed. The kit monitors the status and operation of the selected trip plate through a comprehensive set of feedback signals. The suite supports TMR and simplex backup protection.
