CP1E-N40S1DR-A | Omron | Automate programmable PLC

Description

The Omron CP1E-N40S1DR-A is an application-model CPU unit belonging to the highly versatile CP1E family of micro PLCs. Designed for cost-effective automation, this controller features 40 built-in digital I/O points (comprising 24 input points and 16 relay output points) to manage complex machine sequences. The unit is equipped with a built-in RS-485 communication port alongside a standard USB port, allowing direct integration into industrial networks, HMIs, and frequency inverters without requiring additional serial option boards.

Operating on an AC power supply, the CP1E-N40S1DR-A offers a robust design that excels in space-constrained control panels. It features high-speed processing capabilities, a generous program capacity of 8K steps, and support for CP1W expansion modules to scale the system as application requirements grow. This makes it an exceptional choice for small-to-medium-sized industrial machinery requiring reliable serial communications and rugged solid-state performance.

Features

• Integrated 40-point digital I/O layout with 24 VDC inputs and high-capacity relay outputs.
• Built-in RS-485 port supporting Modbus-RTU Easy Master for simple communication with peripheral devices.
• High-speed USB 2.0 peripheral port for programming, diagnostic monitoring, and system configuration.
• Supports up to three CP1W expansion I/O units or expansion units to scale capabilities.
• Equipped with high-speed counter inputs for rotary encoder interfacing and precise positioning tasks.
• Maintenance-free operational design with battery-free memory backup.

Applications

Installation Guidelines

• Ensure the unit is mounted in an IP54 or higher rated control enclosure to protect against dust, oil, and moisture.
• Install the PLC vertically on a 35mm DIN rail or securely using M4 mounting screws to promote passive convection cooling.
• Maintain a minimum clearance of 50 mm above and below the controller for ventilation.
• Use shielded twisted-pair cables for the RS-485 network and ground the shield at one end only to prevent ground loop interference.

Compliance and Certifications

• CE Mark
• UL Listed (cULus)
• RoHS Compliant
