2. Key Selling Points

1. 32-Point 24 VDC Digital Inputs (High Density)
   Offers 32 input points in a single 40 mm-wide module, doubling the density of 16-point units—ideal for applications with numerous sensors, pushbuttons, or limit switches, reducing the number of I/O slots required.

2. Sinking (NPN) Input Configuration
   Designed for NPN (sinking) transistor sensors—where the sensor connects the input to 0 V (ground) when active. This makes it compatible with widely used NPN output sensors in Asian and global markets.

3. Fast Response Time with Selectable Filtering
   Features a standard response time of 1 ms, with a DIP switch-selectable high-speed mode (0.2 ms) for applications requiring rapid signal detection, such as high-speed counting or fast machine cycles.

4. Compact 40 mm Width for Space Efficiency
   Occupies only 40 mm of rack space on the CJ1/CS1 backplane—maximizing I/O density and minimizing control cabinet size, especially important in compact or retrofit control panels.

5. Individual LED Indicators for Easy Diagnostics
   Each of the 32 input points has a dedicated LED indicator, enabling fast visual confirmation of signal status during commissioning, operation, and troubleshooting—reducing downtime.

6. Optical Isolation & High Noise Immunity
   Provides electrical isolation (opto-couplers) between field devices and the PLC backplane, protecting the CPU from voltage spikes and electrical noise—ensuring stable operation in harsh industrial environments.
