IS220PPROH1A是一种专用的 ，专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，从而提高了运行可靠性并减少了长期维护的需求。该模块通常与TREAH_A端子板配合使用，用于航改型涡轮机紧急跳闸应用，并可以连接到屏障式或箱式接线端子。
IS220PPROH1A具有电压检测的现场布线限制，将电缆长度限制为1000英尺的18 AWG接线。此外，它接受三个速度信号，包括减速、加速和超速，并实现了超速的硬件。
该模块采用前面板，上面标有组件ID号和多个LED指示灯，这些指示灯成对放置，用于指示不同的状态和操作。同时，IS220PPROH1A使用高速处理器和两个完全独立的10/100以太网端口，并配备了硬件复位电路和看门狗定时器。
The IS220PPROH1A is a dedicated I/O module 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, thereby increasing operational reliability and reducing the need for long-term maintenance. This module is typically used in conjunction with TREAH_A terminal boards for emergency trip applications in aero-modified turbines and can be connected to screen or box terminals.
The IS220PPROH1A has field wiring limits for voltage detection, limiting cable length to 1,000 feet of 18 AWG wiring. In addition, it accepts three speed signals, including deceleration, acceleration, and overspeed, and implements hardware for overspeed.
The module features a front panel marked with a component ID number and multiple LED indicators, which are placed in pairs to indicate different states and operations. Meanwhile, the IS220PPROH1A uses a high-speed processor and two fully independent 10/100 Ethernet ports, and is equipped with a hardware reset circuit and a watchdog timer.
