- Input states are continuously monitored and can be read via ASCII commands (EX9052D) or Modbus RTU registers (EX9052D-M).
- The module supports latched input detection, allowing capture of transient pulses that might otherwise be missed during polling.
Use Cases and Applications:
- Industrial automation and process control
- Remote monitoring of digital sensors and switches
- Machine status and alarm signal acquisition
