Selection Summary and Engineering Suggestions

Step 1: Determine the number of I/O points

Calculate the required input and output points, with a 20% margin reserved. The 10/14/20 point model cannot be expanded, while the 30/40/60 point model can expand up to 3 units (see the table above for the maximum I/O points).

Step 2: Select power supply and output type

AC power supply: suitable for occasions with mains power, some models provide 24VDC/300mA external power supply to drive sensors.

DC power supply: suitable for batteries or DC power supply systems, with lower power consumption.

Relay output: suitable for AC loads and low frequency switches.

Transistor output: suitable for DC loads, high-speed pulse output, and PWM output.

Step 3: Determine if advanced features need to be built-in

High speed counting (100kHz): Choose N-type

Pulse output (100kHz, 2-axis): Choose N-type transistor output

Analog input/output: choose NA type (2 inputs/1 output) or install expansion units such as CP1W-AD041/MAD42

Ethernet communication: Choose N30/40/60/NA20 model and install CP1W-CIF41

RS-485 communication: Choose N □ S1 type or install CP1W-CIF11/CIF12-V1

Step 4: Calculate current consumption

Calculate the total current of the 5V and 24V groups to ensure that it does not exceed the power supply capacity. When using a DC power supply, the power consumption calculation formula is:

DC power consumption=(5V current x 5V/70%+24V current) x 1.1

Step 5: Select programming software

CX Programmer (part of CX One) or Micro PLC Edition CX Programmer. Pay attention to the software versions required for different CPU models.
