2. Key Selling Points

1. 16-Channel 24V DC Digital Inputs – High Expansion Capacity:Provides 16 independent digital input points, significantly increasing I/O capacity for small automation systems.

2. Configurable Sinking (NPN) or Sourcing (PNP) Input:Can be set to sinking (NPN) or sourcing (PNP) mode via jumper or wiring, ensuring compatibility with various sensor types and field wiring practices.

3. Group-Based Optical Isolation – Strong Noise Immunity:Inputs are divided into 2 isolated groups (8 points each), with optical isolation between groups and from the CPU, reducing electrical interference.

4. High Response Speed – Suitable for Fast Signal Acquisition:Fast input response time (< 1ms typical), capable of accurately capturing high-speed sensor signals such as proximity switches and pulse inputs.

5. Per-Channel LED Indicators – Clear Status Feedback:Each input has a green LED for real-time visual indication, facilitating commissioning, monitoring, and troubleshooting.
