The Omron CP1E series is a compact, cost-effective panel-mount programmable logic controller (PLC) designed for small-scale automation applications. It offers a balance of performance, expandability, and ease of use, making it an ideal choice for machine builders and system integrators seeking an economical yet powerful control solution.

Key Features & Specifications

• Flexible I/O Configuration: Available in CPU units with 10, 14, 20, 30, 40, or 60 built-in I/O points. The NA20 model features 2 built-in analog inputs (0-10V, 4-20mA) and 1 analog output. Supports up to 3 expansion I/O units and expansion units for adding analog I/O, temperature inputs (thermocouple, RTD), and additional digital I/O.
• High-Speed Positioning & Counting: Transistor output models (N14/20/30/40/60/NA20) feature 2 axes of 100 kHz pulse outputs for precise positioning control (e.g., stepper motors, servo drives). All models include high-speed counters: N/NA models offer 4 axes of 100 kHz single-phase counters; E models offer 6 axes of 10 kHz single-phase counters. Supports input interrupts for high-speed response to external signals.
• Versatile Communication: Standard USB port on all CPU units for easy connection to CX-Programmer software. N/NA-type CPU units include a built-in RS-232C port. Select models (N30/40/60S1) include a built-in RS-485 port. Optional boards (RS-232C, RS-422A/485, Ethernet) can be mounted to N30/40/60 or NA20 CPU units. Supports Modbus-RTU Master, Host Link, NT Link, FINS, and Socket Services (Ethernet option board).
• Expandability for Analog & Temperature Control: With E30/40/60(S), N30/40/60(S@) or NA20 CPU units, analog I/O and temperature inputs can be added by connecting expansion units. This provides a cost-effective way to integrate process control capabilities into a compact PLC system.
• User-Friendly Programming: Programmed using Omron's CX-Programmer software (version 9.12 or higher), which supports ladder diagram programming, function blocks (FB), and structured text (ST for CP1L/CP1H). Features include intuitive instruction entry, automatic address assignment, and offline simulation.
• Built-in Real-Time Clock (Select Models): N/NA-type CPU units include a real-time clock for time-stamped data logging and scheduled operations. Battery backup (CP1W-BAT01) ensures data retention during power loss.
• Compact, Space-Saving Design: All CPU units share a uniform 90 mm width, with depth ranging from 86 mm to 195 mm depending on I/O count. Models with RS-232C connectors (N30/40/60S1) feature a 20 mm depth reduction, enabling installation in shallow control cabinets. DIN rail or direct panel mounting options.
• Robust Environmental Ratings: Operating temperature range of 0°C to 55°C, storage temperature from -20°C to 75°C, and IP20 protection rating for control cabinet installation. Compliant with CE, UL, cUL, NK (Nippon Kaiji Kyokai), Lloyd's Register (LR), and KC certifications.
