Yokogawa  PW301 输入输出模块

是一款脉冲输入/模拟输出模块，兼容横河品牌。它主要用于接收触点开/关、电压脉冲和电流脉冲信号，并可配置在各通道之间，采用双冗余配置。此外，该模块还具有隔离通道，可提供发射机电源等功能。

The Yokogawa AAI143-H53 is a pulse input/analogue output module compatible with the Yokogawa brand. It is mainly used to receive contact open/close, voltage pulse and current pulse signals and can be configured between channels in a dual redundant configuration. In addition, the module has an isolated channel for transmitter power supply and other features.
