OMRON CS1W-ADO41-V1 Analog Output Unit – CS1 Series Programmable Controller
In a modern industrial production line, the precise control of analog signals is the lifeline of process automation. When an analog output module fails or is unavailable, variable-frequency drives lose their speed reference, control valves freeze in position, and the entire process loop collapses — resulting in unplanned downtime, product quality failures, and costly emergency shutdowns. The OMRON CS1W-ADO41-V1 Analog Output Unit is the critical bridge between your PLC logic and the physical world of actuators, drives, and process controllers.
The CS1W-ADO41-V1 is a 4-channel analog output module designed specifically for the OMRON CS1 Series Programmable Controller platform — one of the most widely deployed mid-to-large scale PLC architectures in global industrial automation. Within the CS1W I/O expansion lineup, the ADO41-V1 variant delivers enhanced resolution and signal stability, making it the preferred choice for precision process control applications in industries ranging from chemical processing to semiconductor manufacturing. Its proven reliability and seamless integration with CX-Programmer and Sysmac Studio environments have made it a standard specification in automation projects across Asia, Europe, and the Americas.

Frequently Asked Questions
- Q: Is the CS1W-ADO41-V1 compatible with the CS1G and CS1H CPU series?
- A: Yes. The CS1W-ADO41-V1 is compatible with all CS1G and CS1H CPU units when mounted on a CS1W series backplane. It occupies one I/O slot and is recognized automatically by CX-Programmer during I/O table generation.
- Q: What is the difference between CS1W-ADO41 and CS1W-ADO41-V1?
- A: The V1 revision incorporates improved EMC performance and enhanced output stability compared to the original ADO41. For new installations, the V1 version is strongly recommended. Both versions share the same wiring and software configuration.
- Q: Can I mix voltage and current output on different channels?
- A: Yes. Each of the 4 output channels can be independently configured for voltage (1–5 V or 0–10 V) or current (0–20 mA or 4–20 mA) output via DIP switch settings and CX-Programmer software configuration.
- Q: What happens to the analog outputs if the PLC CPU goes into error mode?
- A: The output behavior on CPU error is configurable. You can set each channel to either hold the last output value or clear to 0 (or 4 mA for 4–20 mA range), depending on your process safety requirements.
- Q: Do you provide a warranty for this module?
- A: Yes. Konmask.com provides a 90-day warranty covering manufacturing defects and functional failures under normal operating conditions. Extended warranty options are available for project orders.
