Material Composition:
Industrial-grade electronic components with standard PCB construction designed for industrial control environments.

Structural Features:
The D4-RSDC module is designed for direct installation onto DL405 series PLC expansion bases. The module features a compact form factor compatible with standard DL405 rack systems.

Working Principle:
The D4-RSDC operates as a remote I/O slave in a master-slave architecture. The module communicates with a remote I/O master module installed in the main PLC rack via RS-485 serial communication. Field I/O modules installed on the remote expansion base connected to the D4-RSDC collect and distribute data, which is transmitted to the master module and then relayed to the PLC CPU. Data updates occur asynchronously with the PLC scan cycle.

Advantages and Strengths:

• Drastically reduces wiring costs by using a single communication cable instead of point-to-point wiring

• Enables flexible I/O module configuration with various DL405 series modules

• Simple addressing and configuration through PLC programming software

• Economical remote I/O solution

• Reduces system maintenance complexity

Applicable Industries:

• Factory automation systems

• Automotive parts manufacturing assembly lines

• Packaging machinery

• Distributed control applications requiring remote I/O

Model Series:
DirectLOGIC DL405 Series Remote I/O System

Installation Requirements:

• Install on any size DL405 series expansion base

• Connect to remote master using twisted pair cable

• Supply 24V DC power to the module

• Ensure proper environmental conditions within specified temperature and humidity ranges

Usage Precautions:

• The module requires a controlled environment for reliable operation

• Storage and installation parameters must be followed to prevent device damage

• Maximum communication distance of 1000 meters must not be exceeded

• The number of slave points varies depending on the CPU module used
