Protection level: IP20, suitable for installation in control cabinets.

Certification: CE, UL, CSA, FM (hazardous area certification), in accordance with IEC 801-2/3 interference immunity standards.

Electrical isolation:

Channel isolation 1000 V AC, effectively preventing ground loop interference, suitable for mixed strong and weak current environments.

Differential input: Schneider 140DDI85300 transmits signals through twisted pair cables, suppresses common mode noise, and the signal transmission distance can reach 100 m.

Wide voltage compatibility:

Schneider 140DDI85300 supports 10–60 V DC input, and can directly connect to devices with different voltage levels such as proximity switches and buttons, reducing the intermediate relay conversion link.

Modular architecture:

Schneider 140DDI85300 supports Quantum series expansion modules, connected to the CPU through the backplane bus, and can expand up to 26 modules.

Distributed I/O: Compatible with Modbus Plus, Ethernet Quantum Remote I/O and third-party devices, supporting cross-segment communication.

Protocol adaptation:

Industrial protocol: Schneider 140DDI85300 supports Modbus TCP and Profinet RT through the CPU module (needs to be paired with a CPU that supports the protocol).

Programming tool: Compatible with Unity Pro and EcoStruxure Control Expert, supports modular programming and version management.

Safety standard:

SIL 2: Schneider 140DDI85300 achieves safety control through the Safety CPU module.
