The R43HCNAR2NSVSOO PACIFIC SCIENTIFIC module has an isolated 24 DC power interface. The input power supply voltage range is 19.2-30V DC, and the power module can use SD821ISD822/SD823. At the same time, the power status signal provided by the SS822 power switching unit can be used to achieve automatic monitoring of power module status and automatic switching of redundant power supplies. Redundant connection is achieved through the matching TU846ITU847 base, including a power interface and two standard D-type 9-pin Profibus connection interfaces. There are also two service interfaces and two address setting rotary switches.

CI840 is connected to the fiber optic Modulebus through TB8O6TB842 or TB846TB842. ClRO1 and CI840 support runtime hot configuration (HCIR) and HART pass through functions. The FCI front panel provides a series of module status display and diagnostic indicator lights. Switching value 1/0 module All l0 modules have a function of isolating from the ground current of the rack. All modules have indicator lights indicating channel status and module status. Some output modules and intrinsic safety modules also have channel error status indication.

PLC内的I/O模板，除一般的DI/DO、AD/DA模板外，还发展了一系列特殊功能的I/O模板，这为PLC用于各行各业打开了出路，如用于条形码识别的ASCII/BASIC模板，用于反馈控制的PID模板，用于运行控制、机械加工的高速计数模板、单轴位置控制模板、双轴位置控制模板、凸轮定位器模板、射频识别接口模板等，这在以后还会有很大发展。另外在输入、输出的相关元件、强干扰场合的输入、输出电隔离、地隔离等方面也会更加完善。
