The Omron CP1L-EL20DR-D PLC CPU Unit combines 12 digital inputs with 8 relay outputs for compact industrial machine-control applications. This Programmable Logic Controller provides a 5K-step program capacity together with 100 kHz high-speed counters across 4 axes for applications requiring fast input counting and sequence processing. The controller operates from a DC power supply and supports Ethernet expansion on the CP1L-EL platform, allowing additional network connectivity where required. Its relay outputs provide electrical switching for general-purpose machine and automation loads. The CP1L-EL20DR-D combines compact CPU processing with relay-based output control and belongs to the compact relay PLC range supporting Omron industrial automation.
