Omron CJ1W-ID261 CJ Series DC Input Unit

Description

Designed for high-density digital signal acquisition within industrial automation environments, the CJ1W-ID261 serves as a reliable 64-point DC input module for Omron CJ-series PLC systems. This high-density module optimizes panel space by consolidating 64 discrete inputs into a compact physical footprint. It interfaces directly with field sensors, switches, and other devices operating at 24 VDC, translating physical input signals into logic states for the CPU. To simplify high-density field wiring, the unit utilizes dual external Fujitsu connectors, dividing the inputs into four isolated groups of 16 points to support versatile circuit configurations.

Features

• High-density 64-point configuration significantly reduces overall rack and panel space requirements.
• Segmented circuit layout features 4 independent circuits (16 points per common) for electrical isolation and flexibility.
• Optimized internal power management with a low current consumption of only 0.09 A at 5 VDC from the backplane.
• Robust Fujitsu connector interfaces ensure secure, long-term connection stability under industrial vibration.
• Allocates 4 words in the PLC memory map for straightforward system configuration and programming.

Applications

• High-density digital signal processing in assembly and manufacturing lines.
• Packaging machinery and material handling conveyor systems.
• Automated sorting systems and warehouse distribution controls.
• Multi-point sensor integration in localized control panels.

Installation Guidelines

• Ensure the CJ-series PLC backplane and system power supply are completely powered down before mounting or removing the input module.
• Use designated CJ-series pre-assembled wiring cables or compatible Fujitsu connectors for quick and secure field termination.
• Keep input signal lines separated from high-voltage AC power lines to minimize electromagnetic interference (EMI) and signal noise.
• Verify that the total current draw of all mounted modules does not exceed the maximum current capacity of the rack's power supply module.
