POINT I/O有4个主要组成部分:I/O模块提供现场接口和系统接口电路·通信接口模块提供网络接口电路

端子座单元为现场侧连接提供接线和信号端接，并为背板提供系统电源

电源分配模块提供POINT I/O系统的可扩展性以及混合各种信号类型的灵活性1734系列I/O模块每个模块提供1至8点。该V/O模块通过通信接口连接到网络，通信接口包括内置电源，可将输入的24V DC电源转换为5V DC背板电源。

每种类型的通信接口(网络适配器）多支持13至17个I/O模块，提供1-A电流。I/O模块从背板上获取电源供电。在使用外部电源的情况下，很好多可将POINTI/O组件扩展至63个I/O模块或5-4个通道。

1734系列POINTBlock I/O提供 DeviceNet通信接口，每个模块很好多集成16个IO点。

POINT I/O has four main components: The I/O module provides the field interface and the system interface circuit; the communication interface module provides the network interface circuit

The terminal block unit provides wiring and signal terminating for field side connections and provides system power to the backplane

Power distribution modules provide scalability for POINT I/O systems and flexibility to mix various signal types The 1734 Series I/O modules provide 1 to 8 points per module. The V/O module is connected to the network through a communication interface that includes a built-in power supply that converts input 24V DC power to 5V DC backplane power.

Each type of communication interface (network adapter) supports 13 to 17 I/O modules, providing 1-A current. The I/O module obtains power from the midplane. In the case of external power supply, many POINTI/O components can be expanded to 63 I/O modules or 5-4 channels.

The 1734 series POINTBlock I/O provides a DeviceNet communication interface, with many integrated 16 IO points per module.
