New Original Omron CP1L-EM40DR-D Compact PLC Controller
1. Product Overview
The CP1L-EM40DR-D is a compact, cost-effective programmable logic controller (PLC) developed by Omron, belonging to the classic CP1L compact PLC series with built-in Ethernet communication function. This unit is a relay output type CPU integrated controller, equipped with 24 digital input points and 16 digital relay output points, targeted at small-scale automation applications including packaging machinery, conveyor lines, injection molding auxiliary equipment, food processing machines, and small assembly stations.
It adopts a DC 24V power supply design, supports standard industrial communication protocols, and reserves expansion interfaces for additional I/O modules, analog modules and special function boards. As an original factory new unit, it undergoes full factory testing for stability, anti-interference performance and long service life, suitable for factory floor harsh industrial environments with vibration, dust and electromagnetic interference. The embedded Ethernet port enables direct connection to HMI, upper computer SCADA systems and other PLCs to realize data upload, remote monitoring and program download without external communication adapters.
