## 4. Functionality

Operating Principle:
The MTISO module provides galvanic isolation by decoupling electrical circuits through non-conductive means such as transformers, optocouplers, or capacitive coupling. This ensures that signals are transmitted accurately without direct electrical connection, preventing interference and protecting equipment from potential differences.

Use Cases and Applications:
- Industrial automation systems requiring isolated signal transmission
- Measurement and control systems with multiple ground references
- PLC and DCS input/output isolation
- Sensor and actuator interface protection
- Communication line isolation (e.g., RS-485, CAN, or analog 4–20 mA loops)
- Laboratory and test equipment requiring high signal fidelity

Compatibility:
- Fully compatible with all MD.. series modules
- Can be integrated into existing installations without redesign
- Supports both analog and digital signal paths depending on the host module

Typical Application Example:
An MD.. analog input module equipped with the MTISO option can safely measure signals from sensors located at different ground potentials, ensuring accurate readings and preventing damage to the control system.
