CT-5800 Terminal module Terminal modules are used to stabilize the internal bus communication. When the number of adapter extension IO modules reaches 16 or more and terminal modules should be required. When the number of adapter extending IO modules is less than 16, and the terminal module CT-5810 only for dustproof could be selected. The dustproof terminal could cover the internal bus and field power supply hardware of the last IO module. And terminal modules have no process data and configuration parameters.
