Product Overview
The CP2E-N40DT1-D is a 40 I/O transistor-type CPU unit within Omron CP2E series compact programmable logic controllers. It features 24 digital inputs and 16 transistor outputs, integrated Ethernet and RS485 communication ports, supporting high-speed pulse outputs for stepper and servo motion control. This controller consolidates logic sequencing, motion positioning and data communication functions, removing the requirement for separate motion control modules in mid-sized automated machinery. Machine builders, control panel engineers and maintenance teams leverage this CPU to build cost-effective automation solutions with flexible networking capability. The unit supports expansion analog and digital modules, enabling scalable system configuration to match evolving production requirements.
Application Scenarios
- Automated Assembly Machines: Executes sequential logic and high-speed positioning control for servo-driven slides, grippers and transfer mechanisms. Built-in Ethernet enables data exchange with HMIs and upper factory monitoring systems.
- Packaging & Labeling Equipment: Handles conveyor tracking, cutter positioning and batch counting. Multiple communication protocols allow seamless connection with variable frequency drives and peripheral sensor equipment.
- Material Handling & Small Conveyor Systems: Monitors safety interlocks, controls sorting diverters and processes photoelectric sensor signals. Expandable architecture supports future upgrades for additional analog process measurement functions.
