Rockwell’s 1746 series of products, part of the SLC 500 series, is a small programmable logic controller (PLC) suitable for a variety of industrial automation and control applications. Products in the 1746 series include:
- The 1746 basic unit provides the basic functions of PLC, such as power supply, processor, memory, communication interface, etc.
- 1746 input/output module provides signal exchange between PLC and external equipment, supports input/output signals of various types and specifications, such as digital, analog, high-speed counter, temperature, position, etc.
- 1746 special function module provides special functions of PLC, such as data collection, motion control, PID control, mathematical operations, ASCII communication, etc.
The product application scenarios of the 1746 series include:
- Industrial automation control systems, such as PLC, HMI, SCADA, etc., can monitor and control the production process through 1746 series products, improving production efficiency and quality.
- Building automation control systems, such as BMS, EMS, etc., can monitor and adjust the building environment through 1746 series products, improving building comfort and energy saving.
- Other occasions where PLC is required, such as laboratories, teaching, testing, etc.
Selection considerations include:
- Select the appropriate basic unit and input/output module according to the application requirements, taking into account factors such as power supply type, processing capability, memory capacity, communication method, number of input/output points, and signal type.
- Select whether special function modules are needed based on application requirements, and consider whether functions such as data collection, motion control, and PID control are necessary.
- Select the appropriate chassis and backplane according to the installation environment, taking into account factors such as chassis size, protection level, and heat dissipation methods.
- Select the appropriate wiring method according to the installation location, taking into account factors such as wiring length, wiring direction, and wiring reliability.
