| Resolution | 1/8,000 (Standard Mode) / 1/4,000 (High-Speed Mode) |
| Conversion Speed | 250 µs/point (Max) |
| Isolation Method | Photocoupler between input terminals and PLC signals |
| Power Consumption | 5V DC, 0.42 A max |
For engineers calculating the power budget of a CJ1 or CJ2 rack, the CJ1W-AD081-V1 is efficient, drawing a maximum of 0.42 A at 5V DC. This low power consumption allows you to stack multiple analog units alongside the CPU without overloading the power supply unit. The module utilizes a removable terminal block, simplifying maintenance by allowing you to disconnect wiring without removing the entire unit from the rack.
When we stock the Omron CJ1W-AD081-V1, we aren’t just supplying a part; we are providing a solution for high-density signal processing. This 8-Point Analog Input Unit is engineered to maximize efficiency in your control cabinet. By handling eight distinct analog signals in a single slot, we help you reduce the physical footprint of your PLC rack without sacrificing performance. This is crucial for US manufacturers looking to optimize panel space while maintaining robust data acquisition capabilities.
The standout feature of this CJ Series PLC Module is its flexibility. You are not locked into a single signal type for the entire card. We can configure each point independently, allowing a mix of a 4-20mA Input Module setup on one channel and a 0-10V Analog Converter on another. This reduces the need to carry multiple spare part variations.
To ensure your system runs smoothly, pairing this input module with a reliable Omron CJ Series 16-point relay output unit creates a balanced and compact I/O architecture.
Core Performance Highlights:
| Feature | Benefit |
|---|---|
| High-Density Design | Manages 8 analog signals in one slot, saving valuable rack space. |
| Signal Flexibility | Independent range settings (1-5V, 0-10V, 4-20mA) for every point. |
| Smart Processing | Built-in scaling, mean value processing, and peak hold functions reduce CPU load. |
| Disconnect Detection | Automatically detects broken wires for 1-5V and 4-20mA signals to prevent errors. |
This unit delivers High-Resolution Analog Input data directly to the CPU, ensuring your process control is based on stable, accurate readings. The built-in disconnect detection adds a layer of safety, instantly alerting the system if a sensor wire breaks, which prevents false data from disrupting your operations.
Integrating the Omron CJ1W-AD081-V1 into your control panel is designed to be efficient and reliable. As a standard CJ Series PLC Module, this unit mounts directly to the backplane of any CJ1 or CJ2 CPU rack. The modular design allows you to snap the unit into place on the DIN rail without special tools, making it easy to expand your system’s capabilities. Ensure the locking slider is fully engaged to maintain a secure connection, especially in environments subject to vibration.
One of the practical benefits of this unit is the removable terminal block. This feature simplifies maintenance since you don’t have to disconnect individual wires to replace the module. When following the AD081-V1 Wiring Diagram, keep these best practices in mind:
Setting up the Omron CJ1 Analog I/O parameters is handled through the CX-Programmer software. You do not need to write complex ladder logic to initialize the unit. Instead, you configure the I/O table to define the unit number and select the specific signal ranges (such as 4-20mA or 0-10V) for each of the 8 points. This software-based configuration ensures that your CJ1 System Compatibility is optimized for the specific sensors connected to the system.
When you source the Omron CJ1W-AD081-V1 from Duomi, you are prioritizing reliability and speed.
