A Single Unit for All Your Analog Input Needs
It is a unit with fully universal inputs. This means you can connect different types of sensors to just one module. It is perfect for inputs such as temperature sensor types like a resistance thermometer, thermocouple, and DC signals. You don’t need a separate module for your RTD PT100 and another one for your 4 to 20 mA transmitter.
This one unit does it all. It simplifies your design and purchasing. You stock fewer parts. You spend less time wiring. This makes your whole automation system more efficient.
Seamless Integration with Omron CJ1 CPU Units
This input unit is made for the Omron Sysmac CJ1 series. It slides easily onto any CJ1 backplane. It works with all CJ1 CPU units. The input module talks directly to the PLC. The scaled values are transferred to the CPU unit in simple four digits hexadecimal format.
High-Speed and High-Resolution Analog Data
In industrial automation, speed and accuracy are key. You need to trust your data. The CJ1W-AD04U delivers high-speed and high-resolution performance. It can read all four input points in just 20 milliseconds. This is very fast. It means your PLC always has up-to-date information.
You can detect small changes in temperature, pressure, or flow. This leads to better quality and less waste. Whether you are using a 1 to 5 V signal or a thermocouple, you get accurate data you can rely on. This level of performance is critical for modern manufacturing.
Built for the Factory Floor: Easy and Reliable
Industrial environments are tough. You need gear that can handle it. The Omron CJ1W-AD04U is built to last. It mounts securely on a DIN rail inside your panel. The wiring terminals are easy to access and secure. Importantly, the inputs are isolated from each other. This stops electrical noise from causing bad readings.

Frequently Asked Questions
The CJ1W-AD04U is designed specifically for the Omron Sysmac CJ1 series PLC family, including CJ1M, CJ1G, and CJ1H CPU units. It mounts on either the main CPU rack or an expansion rack.
Yes, absolutely. This is its main advantage. You can mix and match inputs. For example, you can connect a thermocouple to input 1, a PT100 sensor to input 2, a 4-20mA pressure transmitter to input 3, and a 0-10V signal to input 4, all on the same module.
The unit uses a detachable 18-point terminal block for easy wiring. The user manual provides detailed diagrams for connecting each type of input, such as voltage, current, resistance thermometer, thermocouple, and DC signals.
Yes, we do. We have a team of automation experts ready to help you with product selection, installation, and troubleshooting. We offer full technical support to ensure your project is a success.
