　　IS220PPROH1A接受三种速度信号。 这包括减速、加速和超速。该组件还具有超速实现的硬件。该套件通过一组全面的反馈信号监控所选绊板的状态和操作。该套件支持 TMR 和单工备份保护。

　　该IS220PPROH1A内置高速处理器和两个完全独立的 10/100 以太网端口。该套件具有硬件复位电路和看门狗定时器。温度由内部传感器监控。

　　IS220PPROH1A is a turbine dedicated! Module /0. It is designed to provide a direct interface to specific turbine site equipment. This setup eliminates or reduces the large number of instruments previously required to connect field equipment, and also improves operational reliability and reduces long-term maintenance. The 1S220PPROH1A is usually used in conjunction with the TREAH A terminal plate for emergency trip applications in aero modified steam turbines. The component can be connected to a barrier or box terminal plate. The IS220PPROH1A has field wiring limits for voltage detection, limiting cable length to 1,000 feet of 18 AWG wiring. It should be noted that the IS220PPROH1A cannot be automatically reconfigured when exchanging BPPB P-Pack with BPPC P-Pack.

　　The front panel of the IS220PPROH1A is marked with the component id number and several LED indicators. These 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.
