JOHNSON CONTROLS控制模块PCX系列介绍
PCX 是具有集成 RS-485 MS/TP 通信功能的扩展 I/O 模块。
当安装在 PCA 控制器的传感器执行器 (SA) 总线上时，PCX 扩展了控制器的 I/O 接口。 当安装在现场控制器 (FC) 总线上时，PCX 可以用作 I/O 点多路复用器，以支持监控控制器的监视和控制。 点多路复用器还可用于使用点对点连接在 FC 总线上的其他 PC 控制器之间共享点。PCX 可以发挥两种功能之一的作用，具体取决于它们在控制系统中的安装位置。
全系列 PCA 模型与 PCX 模型相结合，可应用于各种建筑应用，从简单的风机盘管或热泵控制到中央工厂管理。
The PCXs are expansion I/O modules with integral RS-485 MS/TP communications.
When installed on the Sensor Actuator (SA) Bus of PCA controllers, the PCXs expand the I/O interfaces of the controllers. When installed on the Field Controller (FC) Bus, PCXs can be used as I/O point multiplexors to support monitoring and control from a supervisory controller. The point multiplexor can also be useful for sharing points between other PC controllers on the FC Bus using peer-to-peer connectivity. PCXs can serve in one of two capacities, depending on where they are installed in the control system.
A full range of PCA models combined with the PCX models can be applied to a wide variety of building applications ranging from simple fan coil or heat pump control to advanced central plant management.
