### 4. Functionality

The EX9063B functions as a distributed digital I/O node in an RS-485 network. It provides signal acquisition and control capabilities for automation systems, enabling remote monitoring and actuation of digital signals.

Operation Principle:
- Digital Inputs: Accept TTL, CMOS, or dry contact signals. Each input is optically isolated to prevent interference and protect the host system.
- Relay Outputs: The three DC-SSR outputs act as electronic switches, capable of driving DC loads such as solenoids, indicators, or control relays.
- Communication: The module exchanges data with a host controller (PLC, PC, or HMI) via Modbus RTU commands.
- Watchdog Function: Ensures outputs revert to predefined “Safe Values” if communication is lost or the host fails.
- EEPROM Configuration: Stores module address, baud rate, and protocol settings, retained even after power loss.
- INIT* Mode: Allows resetting or reconfiguring communication parameters by grounding the INIT* pin or toggling the rear INIT switch.

Typical Applications:
- Industrial automation and process control
- Building management systems (BMS)
- Remote equipment monitoring
- Machine control and safety interlocks
- Energy management and environmental monitoring
- Distributed I/O expansion for PLCs and SCADA systems

Compatibility:
- Compatible with Modbus RTU master devices such as Siemens, Schneider, Allen-Bradley, and Omron PLCs.
- Integrates with SCADA software (e.g., Wonderware, Ignition, Citect, LabVIEW).
- Works with ExpertDAQ configuration utilities and third-party Modbus tools.
