Components of Allen-Bradley 1746

CPU modules

These modules, such as the 1746-L23, are the "brain" of the PLC, responsible for executing the programmed logic.


I/O modules

I/O modules handle the input and output signals to and from the PLC, allowing it to interact with the external world. Examples include relay output modules (e.g., 1746-OW16) and digital input modules.

Chassis

The 1746-A7 and 1746-A10 are examples of chassis, which are the housings that hold the various modules of the SLC 500.

Power supplies

Modules like the 1746-P4 and 1746-P3 provide the necessary power to the PLC system.

Communication modules

These modules enable communication between the PLC and other devices or systems, such as a HMI or a network.

 

Application of Allen-Bradley 1746

 

 

Allen-Bradley 1746-NI4 SLC 4-point analog input module is an analog input device for industrial automation control systems and belongs to the Allen-Bradley SLC 500 series. It has 4 analog input channels, and users can select voltage or current input mode for each channel.

It is mainly used to convert analog signals (such as voltage and current signals) at industrial sites into digital signals for processing by programmable logic controllers (PLCs), thereby realizing monitoring and control of industrial processes.

It can be used to connect pressure transmitters (4-20mA) and thermocouples (signal conditioners are required); adjust the inverter or valve opening according to analog feedback; and realize batch data storage through RSLogix 500 programming.
