### 4. Functionality
The W‑M1B402 operates as a remote digital output node in an RS‑485 Modbus network. A host controller—such as a PLC, PAC, or industrial PC—issues Modbus commands to control each output channel. The module responds by switching its NPN transistors to sink current from external loads (e.g., solenoids, lamps, or relays).
Typical Use Cases:
- Industrial process control and machine automation
- Distributed digital output expansion for PLCs
- Building and energy management systems
- Security and alarm signaling
- Laboratory and test automation
- Supervisory control and data acquisition (SCADA) systems
Compatibility:
Fully compatible with standard Modbus/RTU masters and SCADA software. Can be integrated with Advanio’s Wolf Series analog, relay, and mixed I/O modules for complete distributed control solutions.
