SmartDraw helps you make block diagrams easily with built-in automation and block diagram templates. As you add shapes, they will connect and remain connected even if you need to move or delete items.

Feb 6, 2020 · In the following block diagram, input and output modules are connected through the brain of PLC i.e. Central Processing Unit (CPU). The input device provides a signal to an input module. This input module is connected with the CPU for the initial automated processes.

Figure 3 reflects the conceptual block diagram. Figure 3. HSDO Module Block Diagram. Table 1 lists the target specifications for the HSDO module. This design targets a single-ended output. See TI Design TIDA-00766 for a counterpart in differential-ended output implementation.

Figure 4 shows the block diagram for one output of a typical discrete output module. Like the input module, it is composed of two basic sections: the power section and the logic section, coupled by an isolation circuit.

Apr 24, 2017 · The block diagram of programming logic controller (PLC) is shown in above figure. The PLC has following basic sections are, The processor section is brain of PLC which consists of RAM, ROM, logic solver and user memory. The central processing unit is heart of PLC. CPU controls monitors and supervises all operation within PLC.
