### 4. Functionality
The EX9065B functions as a distributed digital I/O node in an RS‑485 network. It converts field‑level digital signals into serial data for transmission to a host controller or PLC.
Operation Principle:
- Digital Inputs: Accept dry contact, TTL, or CMOS signals. Each input is optically isolated to prevent interference.
- Digital Outputs: The 5 DC‑SSR outputs act as electronic switches for DC loads such as solenoids, LEDs, or relays.
- Communication: The module exchanges data with a master device using ASCII or Modbus RTU commands.
- Configuration: Parameters such as address, baud rate, and data format are stored in EEPROM and can be modified via serial commands or software tools.
- Watchdog Control: If communication is lost, outputs revert to predefined “Safe Values” to ensure system safety.
Typical Applications:
- Industrial automation and process control
- Remote digital signal monitoring
- Machine control and equipment interlocking
- Building automation and HVAC systems
- Energy management and distributed I/O expansion
Compatibility:
- Compatible with any Modbus RTU master (PLC, SCADA, HMI, or PC‑based control system)
