3. Main Functions
- Multi-Signal Range Support: Each output point can independently select a voltage range (e.g., 0-10V or ±10V).
- High resolution: Supports 12-bit (1/4000) or 13-bit (1/8000) resolution for precision control.
- Output Hold Function: Holds the last output value when the PLC is stopped or communication is interrupted.
- Offset/Gain Adjustment: Support manual calibration to improve output accuracy.
- High-speed D/A conversion: Some models support 250μs high-speed conversion (e.g., CJ1W-DA042V).

4. Typical Applications
- Industrial automation: used to control inverters, servo motors, proportional valves and other equipment.
- Process control: such as temperature, pressure, flow and other analog adjustments.
- Energy management: Combine A/D modules for energy consumption monitoring and optimization.
- Device condition monitoring: Output analog signals to drive the HMI or recorder.

5. Installation and maintenance
- Installation environment: It is recommended to use in the range of 5.6°C~60°C to avoid strong electromagnetic interference.
- Heat dissipation requirements: Reserve ≥5cm space around the module to ensure heat dissipation.
- Maintenance suggestion: Regularly check the connection status of the terminals to prevent abnormal signals caused by poor contact.

6. Compatibility
- Compatible with CJ series PLCs and can be combined with other I/O modules such as digital input/output, communication modules.
- Supports communication protocols such as Modbus TCP/IP for easy integration into industrial Ethernet systems.

summary
The CJ1W-DA08V is a high-precision, high-reliability analog output module suitable for various industrial automation applications. Its flexible configuration, high-speed conversion, and stable performance make it an important component in PLC control systems.
