Many engineers reviewing Omron CP1L-EL20DT1-D also explore Siemens PLC, Omron SMPS 24V 10A and Nx1P2 1040Dt1, ensuring they donβt miss strong alternatives before finalizing procurement decisions.
Omron CP1L-EL20DT1-D Programmable Logic Controller
The Omron CP1L-EL20DT1-D Programmable Logic Controller (PLC) is a compact and efficient CPU Unit featuring 20 I/O points with 12 inputs and 8 sourcing transistor outputs. Designed for small machine control, it offers a 5K-step program capacity, 100 kHz high-speed counters (4 axes), and 100 kHz pulse outputs for light positioning applications. Powered by DC, it supports Ethernet expansion and integrates smoothly with sensors, drives, and field devices. Manufactured by Omron, part of the Omron Programmable Logic Controller family under the Omron CP1L Series.
