### 4. Functionality
The EX9050HD functions as a distributed digital I/O node in an RS-485 network. It converts digital input signals from sensors, switches, or logic devices into serial data for transmission to a host controller, and conversely, it receives digital output commands to control actuators, relays, or indicators.
Operation Principle:
- Inputs: The 8 source-type digital inputs detect voltage levels between +3.5 V and +30 V as logic high. Each input channel is monitored and its state is transmitted to the host system upon request.
- Outputs: The 8 open-collector NPN outputs act as current sinks, switching external loads connected to +V. Each output can drive up to 30 mA at voltages up to 30 VDC.
- Communication: The module communicates via RS-485 using ASCII or Modbus RTU protocol. Commands can read input states, set output states, configure parameters, or monitor status.
- Watchdog Function: Ensures outputs revert to a predefined safe state if communication is lost or the host fails.
- EEPROM Configuration: Stores address, baud rate, and operational parameters, retained through power cycles.
- INIT* Mode: Allows resetting or reconfiguring the module by toggling the rear-mounted INIT* switch.
Typical Applications:
- Industrial automation and process control
- Building management systems (BMS)
- Remote monitoring and control of machinery
- Environmental data acquisition
- Distributed I/O expansion for PLCs and SCADA systems
- Equipment status monitoring and alarm signaling
