### 4. Functionality

The EX9063BD‑M functions as a distributed digital I/O node on an RS‑485 network. It converts field‑level digital signals into Modbus RTU data accessible by a host controller.

Operation:
- Inputs: Detect ON/OFF states from sensors, switches, or TTL/CMOS logic.
- Outputs: Drive external DC loads such as solenoids, lamps, or actuators through SSR channels.
- Communication: The module exchanges data using Modbus RTU function codes (01, 02, 05, 0F, 03, 06) for reading/writing coils and registers.
- Watchdog: If communication fails, outputs revert to predefined *Safe Values* to prevent unintended operation.

Typical Applications:
- Industrial automation and process control
- Building management systems
- Remote equipment monitoring
- Machine I/O expansion
- Energy management and environmental monitoring

Compatibility:
Works with any Modbus RTU master device (PLC, HMI, SCADA, or PC‑based controller). Configuration and monitoring can be performed using ExpertDAQ software utilities or third‑party Modbus tools.
