4. Functionality

The EX9017H‑M converts analog voltage or current signals into digital data using a 16‑bit A/D converter. Each channel’s range is independently programmable, allowing mixed‑signal acquisition within a single module. The digitized data are transmitted to a host controller or SCADA system via Modbus‑RTU over RS‑485. The MTCP variant communicates over Ethernet using Modbus/TCP or UDP, enabling direct integration with PLCs, HMIs, or PCs.

Typical Use Cases:
- Industrial process monitoring (temperature, pressure, flow, level).
- Data logging and remote telemetry.
- Laboratory instrumentation and test benches.
- Building automation and energy management.
- Integration with distributed control systems (DCS) or SCADA platforms.

Compatibility:
- Modbus‑RTU and Modbus/TCP compliant controllers.
- ExpertDAQ Utility, Modbus OPC servers, and third‑party HMI/SCADA software.
- Custom applications via provided DLL and ActiveX interfaces.
