### 4. Functionality
The EX9060D‑M functions as a distributed digital I/O node in an RS‑485 network. It converts field‑level digital signals into Modbus RTU data accessible by supervisory controllers or PLCs.
Operation Principle:
- Digital Inputs: Each input channel detects voltage levels from external sensors, switches, or logic devices. The opto‑isolation barrier protects the internal circuitry from high‑voltage transients.
- Relay Outputs: Each relay channel can switch AC or DC loads such as solenoids, contactors, lamps, or alarms. Two Form A (Normally Open) and two Form C (Changeover) contacts provide flexible control options.
- Communication: The module exchanges data via RS‑485 using Modbus RTU commands. It supports standard Modbus function codes (0x01, 0x02, 0x03, 0x04, 0x05, 0x0F, 0x06) for reading/writing I/O status, counters, and configuration parameters.
- Watchdog Protection: If communication is lost or the host fails, the module automatically sets outputs to predefined Safe Values to prevent uncontrolled states.
- EEPROM Storage: All configuration parameters (address, baud rate, protocol mode) are stored in non‑volatile memory.
Typical Applications:
- Industrial automation and process control
- Building management systems (BMS)
- Remote monitoring and data acquisition (SCADA)
- Machine status monitoring and alarm signaling
- Energy management and environmental control
- Distributed relay control in factory automation
Compatibility:
- Compatible with any Modbus RTU master device (PLC, HMI, SCADA software).
- Integrates with ExpertDAQ EX9000 series modules for mixed I/O systems.
- Supports standard RS‑485 network topologies with termination and bias resistors.
