Filter time: 2, 4, 8, 16ms can be selected.
Isolation mode: Isolated from the ground in groups, with voltage monitoring. Each input channel consists of a current limiting element, an EMC protection element, an input status indicator LED and a photoelectric isolation gate.

Environmental parameter
Operating temperature: -40°C to + 70°C.
Storage temperature: No special restrictions mentioned.
Relative humidity: No special restrictions are mentioned, and generally the humidity range of a common industrial environment.
Electromagnetic compatibility: comply with IEC 61131-2, IEC 61000-6-2, IEC 61000-6-4 and other standards.

Other characteristics
Front panel LED indicator: Displays the input status of each channel.
Status indicator: The module has a diagnostic function, can monitor the input status, can detect the fault or error of the input signal, and through the corresponding indication or signal feedback.
Compatibility: Compatible with ABB PLC and related control systems.
Hot swap function: Supports hot swap, which can replace or add modules while the system is running, reducing downtime and maintenance costs
