Omron CJ1W-DA041 4-Channel Analog Output Module for CJ Series PLCs

Product Overview

The CJ1W-DA041 module converts digital data received from the CPU unit into analog output signals suitable for controlling analog field instruments. Each of the four outputs can be independently configured for either voltage or current operation, with a comprehensive selection of industry-standard signal ranges. This flexibility allows a single module to accommodate mixed signal types within the same installation, reducing the number of modules required and simplifying system design. The module supports signal ranges including 0 to 5 V, 0 to 10 V, 1 to 5 V, -10 to +10 V for voltage outputs, and 4 to 20 mA for current outputs, covering the vast majority of analog control applications in industrial automation.

Key Features

• Independent Channel Configuration: Each output channel can be configured with a different signal range

• Removable Terminal Block: Facilitates easy wiring changes and module replacement without rewiring

• External Power Supply: Operates on 24 V DC external power with 200 mA maximum current requirement

• High Accuracy: Voltage output accuracy of ±0.3% of full scale at 25°C ambient temperature

• Current Output Accuracy: ±0.5% of full scale at 25°C ambient temperature

• Fast Update Rate: Conversion period of 1 ms per point for responsive control loops

• Compact Profile: Dimensions of 90 x 31 x 65 mm for space-efficient cabinet mounting

Technical Specifications

System Integration with CJ Series

The CJ1W-DA041 module is fully compatible with the complete Omron CJ series PLC line including CJ1G, CJ1H, and CJ2 CPU units. The module occupies a single unit number slot on the CJ series backplane and communicates with the CPU unit via the high-speed CJ system bus. Data exchange between the CPU and the analog output module occurs automatically during each system scan cycle, with the module reading output data from designated DM Area words and converting the values to analog output signals. The module‘s allocation of unit numbers can be configured through the CX-Programmer software, providing flexible addressing options for large systems with multiple analog modules.

Applications

• Process Control: Analog setpoint generation for temperature, pressure, and flow controllers

• Motion Control: Speed and torque reference signals for drive systems

• Test and Measurement: Signal generation for equipment testing and validation

• Machine Automation: Control of analog actuators and positioning systems

• Building Automation: HVAC damper and valve control applications
