CJ1W-DA08C 8-Channel Analog Output Module for PLC Systems

Product Overview

The Omron CJ1W-DA08C is a premium 16-bit analog output module engineered for industrial automation systems requiring uncompromising precision and reliability. As part of the CJ Series programmable logic controller (PLC) ecosystem, this DIN rail-mounted unit delivers eight fully isolated channels for converting digital control signals into analog voltage or current outputs. Designed for harsh industrial environments, it features advanced noise immunity and ±0.3% voltage accuracy to maintain signal integrity in applications ranging from precision manufacturing to critical process control. With Omron's proven CJ-series architecture, this module enables seamless integration with existing PLC racks while meeting ISO 9001 quality standards for industrial components.

Key Features

• Multi-Format Output Capability: Independently configure each of 8 channels for voltage (0-10V, ±10V, 1-5V) or current (0-20mA, 4-20mA) output without external signal conditioners
• Industrial-Grade Precision: 16-bit resolution (1/4000) with ±0.3% F.S. voltage accuracy (±0.5% F.S. current) ensures stable control of sensitive actuators and process variables
• Synchronized Output Refresh: Simultaneous update of all channels within 1ms eliminates timing skew in multi-axis motion control systems
• Enhanced Electrical Protection: Built-in photocoupler isolation (2,300V AC for 1min) safeguards PLC backplane from ground loops and transient spikes
• High-Density Design: Space-optimized 31mm width (3 slots) accommodates complex I/O configurations in control panels
• Rugged Construction: Operates reliably in 0-55°C environments with 90% non-condensing humidity and 147m/s² shock resistance
• Energy-Efficient Operation: 1W power consumption (5VDC @ 0.2A) via PLC backplane reduces thermal load in enclosed cabinets
• Omron Quality Assurance: Includes 1-year manufacturer warranty with traceable calibration certificate

Industrial Applications

Optimized for Industry 4.0 implementations, the CJ1W-DA08C enables precise analog control across multiple sectors:

• Advanced Manufacturing: Closed-loop control of servo presses, CNC machine tools, and robotic welding systems
• Process Industries: Continuous regulation of pH levels, viscosity, and pressure in chemical reactors and pharmaceutical batch processes
• Energy Systems: Output scaling for turbine governor controls, solar tracker positioning, and battery formation equipment
• Building Automation: Analog signal generation for VAV damper controls, chiller plant optimization, and fire suppression systems
• Test & Validation: Precision signal output for automotive ECU testing, aerospace component burn-in, and medical device calibration
