### 4. Functionality

The W‑M1B302 operates as a remote digital input acquisition module on an RS‑485 Modbus/RTU network. A host controller (PLC, PAC, or PC) polls the module to read input states or counter values. Each input channel can detect either dry contact closures or voltage‑driven wet signals, making it suitable for interfacing with switches, sensors, relays, and logic outputs.

Use Cases & Applications:
- Industrial process monitoring and control
- Remote data acquisition systems
- Energy management and power distribution monitoring
- Building and facility automation
- Security and alarm systems
