### 4. Functionality
Operating Principle:
The EX9066A‑MTCP converts Ethernet‑based Modbus/TCP commands into isolated digital input and relay output operations. Each input channel can detect dry or wet contact signals, while each relay output can switch AC or DC loads. The module acts as a Modbus/TCP slave (server), responding to queries from a host controller, PLC, or SCADA system.

Use Cases & Applications:
- Industrial process control and machine automation.
- Remote facility monitoring and alarm systems.
- Building automation (lighting, HVAC, access control).
- Energy management and equipment status feedback.
- Integration with Modbus‑enabled PLCs, HMIs, or OPC servers.

Compatibility:
Fully compatible with Modbus/TCP clients, ExpertDAQ Utility, and third‑party SCADA software (e.g., Wonderware, iFIX, Citect, LabVIEW). Supports both TCP and UDP communication for flexible network integration.
