The OMRON CJ1W-CTL41-E

The OMRON CJ1W-CTL41-E is a high-performance, four-channel counter unit designed for the CJ-series PLC systems. This versatile unit supports both incremental encoders and line drivers, allowing for a maximum input frequency of 100 kHz. It is ideal for applications requiring precise control over fast motions, with bi-directional counting capabilities to detect movement in either direction.

Key Features:

• Flexible Configuration: Each counter can be configured independently, allowing you to tailor the unit to your specific application needs. Choose from circular or linear counter types and configure output control modes in either range or comparison mode.
• Robust Output Control: The unit supports up to 32 software outputs per counter, each linked to specific counter events. Outputs can be controlled based on configurable ranges or comparison values, ensuring precise control over your system.
• Interrupt Capabilities: The CJ1W-CTL41-E can generate interrupts to the PLC CPU, enabling immediate action upon counter events when mounted in a CPU rack.
• Noise Filtering and Hysteresis: Integrated noise filters help suppress signal noise, while configurable hysteresis prevents output toggling due to oscillations.
• Runtime Configuration: Settings can be adjusted at runtime using the IOWR instruction, allowing for seamless adaptation to changing application needs without halting operations.

Technical Specifications:

• Input Type: Supports incremental encoders with phase differential inputs, up/down pulse inputs, and pulse & direction inputs.
• Maximum Input Frequency: 100 kHz.
• Number of Encoder Input Channels: 4.
• Dimensions: 95.4 mm (height), 31 mm (width), and 83.6 mm (depth).
• Weight: 160 g.

Safety and Compatibility:

The CJ1W-CTL41-E is designed for use with CJ-series CPU racks and expansion racks, ensuring compatibility within OMRON’s PLC ecosystem. Always follow the operation manual and safety guidelines to ensure safe and effective use.
