A-B 1756-DNB
The Allen-Bradley 1756-DNB module is a digital input module designed by Rockwell Automation for the ControlLogix platform. It is used to collect discrete signals from various digital devices (such as switches, sensors, buttons, etc.) and convert them into digital signals that can be recognized by the PLC. This module is usually used in industrial automation system to realize the monitoring and control of equipment.
Main functions:
Digital signal acquisition: Collect digital signals from external devices, such as switch status, sensor signals, etc.
Signal isolation: Provide signal isolation function to prevent the impact of external interference on the PLC.
Fault diagnosis: The built-in self-diagnosis function of the module can detect the fault of the module itself.
