OMRON CP1W-DA041 Analog Output Expansion Unit – CP1W Series
When a production line loses precise analog output control, the consequences cascade instantly: variable-frequency drives receive no speed reference signal, proportional control valves freeze in position, and temperature regulators go blind. A missing or failed analog output module doesn’t just pause a machine — it can halt an entire process cell, trigger emergency shutdowns, and cost thousands of dollars per hour in unplanned downtime. In precision-driven industries such as chemical dosing, food processing, and semiconductor fabrication, analog signal integrity is not optional — it is the backbone of closed-loop control.
The OMRON CP1W-DA041 is a 4-channel analog output expansion unit purpose-built for the CP1W modular expansion ecosystem, compatible with OMRON’s CP1L and CP1H series PLCs. Within the CP1W family, the DA041 occupies the role of high-density analog output — delivering four independent channels of voltage or current output with 1/4000 resolution, making it the preferred choice for engineers who need fine-grained process control without stepping up to a larger PLC platform. Globally, OMRON’s CP1 series is deployed across millions of machine automation nodes, and the CP1W-DA041 is a cornerstone module wherever multi-channel analog output is required in a compact footprint.

- High Resolution (1/4000): Fine-grained 12-bit resolution ensures smooth, precise analog signal delivery — critical for proportional valve control, speed regulation, and process setpoint transmission.
- Fast Conversion Speed: 1 ms per channel conversion time supports responsive closed-loop control without introducing latency into the control loop.
- Seamless CP1W Bus Integration: Plug-and-play expansion onto CP1L/CP1H PLCs via the CP1W side bus connector — no additional wiring harness or communication configuration required.
- Compact DIN-Rail Form Factor: Minimizes panel space consumption while delivering full industrial-grade analog output capability.
- Wide Operating Temperature Range: Rated 0–55°C for reliable operation in factory floor environments without additional thermal management.
