Omron CJ1W-AD081-V1 CJ Series Analog Input Module

Description

Designed for precise process automation within the Omron Sysmac CJ1 and CJ2 system architectures, the CJ1W-AD081-V1 serves as a high-density analog input module processing up to 8 independent industrial signals. This unit allows configurable range selection for each input channel, facilitating seamless integration of standard voltage and current signals from field transmitters directly into PLC memory.

This module features an advanced analog-to-digital converter core where speed and resolution can be tailored to application requirements. For standard operations, a resolution of 1/4,000 operates at a conversion period of 1 ms per point. For highly dynamic processes, users can select a high-resolution mode of 1/8,000 with an ultra-fast conversion period of 250 microseconds per point. These parameters are linked configuration profiles to ensure conversion stability and hardware reliability.

Features

• 8 high-density analog input channels with individual signal range configuration.
• Supports multiple standard industrial signal inputs, including 1 to 5 V, 0 to 5 V, 0 to 10 V, -10 to 10 V, and 4 to 20 mA.
• Configurable analog resolution settings of 1/4,000 or 1/8,000 depending on processing speed needs.
• Selectable conversion periods of 1 ms/point or 250 microseconds/point.
• Removable terminal block interface facilitates pre-wiring and minimizes system downtime during maintenance.
• Allocates a single unit number within the PLC CPU rack configuration for efficient memory usage.

Applications

• Process monitoring (temperature, pressure, flow, and level transmitter integration).
• Industrial waste and clean water treatment control plants.
• Multi-axis machine tool automation and general manufacturing equipment.
• HVAC, environmental chambers, and building automation setups.

Installation Guidelines

• Mount the module securely to the CJ-series backplane, ensuring the top and bottom interlocking sliders are completely locked.
• Always disconnect the PLC power supply before inserting, removing, or wiring the module.
• Route analog signal wires separately from high-voltage AC cables and motor drive lines to prevent electromagnetic noise coupling.
• Utilize shielded twisted-pair cables for all field sensor signals, connecting the shield only to the system ground terminal on the PLC side.
• Ensure the removable terminal block is seated flush and the retention screws are tightened before putting the unit into active service.
