PDAA401 3BSE017234R1 I/O Module

PDAA401 3BSE017234R1 I/O Module

The controller of PDAA401 3BSE017234R1 controls the work of the CPU, which reads instructions, interprets them and executes them. However, the working rhythm is controlled by oscillating signals. Operators are used to perform digital or logical operations and work under the command of the controller. Registers are involved in the operations and store the intermediate results of the operations, which also work under the command of the controller.

The interface between the PDAA401 3BSE017234R1 and the electrical circuitry is accomplished through the Input/Output section (I/O).The I/O module integrates the PLC’s I/O circuitry with input staging registers that reflect the state of the input signals and output points that reflect the state of the output latches. The input module converts electrical signals into digital signals into the PLC system, and the output module is the opposite.I/O is divided into switching input (DI), switching output (DO), analog input (AI), analog output (AO) and other modules.
