Step 1: Select Communication Protocol
Selecting a suitable communication protocol is the first step in the configuration of RS IO modules.RS series IO modules support a variety of communication protocols, including CC-Link, EtherCAT, PROFINET, EtherNet/IP, and Modbus/TCP, and each protocol has its own specific advantages and applicable scenarios. Choosing the right protocol will ensure that your IO modules are compatible with your existing automation control system, ensuring efficient system operation.

Step 2: Select Signal Type
RS series modules support a variety of signal types, including 16DI PNP type, 16DI NPN type, 16DO PNP type, 16DO NPN type, 8DI8DO PNP type, 8DI8DO NPN type, 8DO, and 8AI. Digital input and output are suitable for simple switch signal control, while analog input is more suitable for reading continuous data from devices such as sensors. Digital inputs and outputs are suitable for simple switching signal control, while analog inputs are more suitable for reading continuous data from devices such as sensors.
Step 3: Select Base Slot (Single/Dual)
The RS series offers both single-slot chassis and dual-slot chassis. The single-slot chassis is suitable for small applications that require 16 points of inputs and outputs, while the dual-slot chassis is suitable for systems that require more inputs and outputs, supporting up to 32 points of inputs and outputs. The dual-slot chassis also supports the free combination of multiple panels, such as digital + analog, providing you with greater flexibility and expandability.


Step 4: Select Terminal Type
Choosing the right terminal type is important to simplify installation and wiring, and RS-Series IO modules offer a variety of terminal types, including trinity Euro terminals, single-row Euro terminals, and E-CON connectors. Different terminal types are suitable for different wiring requirements. Trinity Euro terminals are suitable for high-density wiring, single-row Euro terminals are the most common wiring method, and E-CON connectors are suitable for systems that require modular wiring.
How to Customise the RS IO Module
Choosing the right RS IO module depends on your specific automation needs. Start by selecting a communication protocol (CC-Link, EtherCAT, PROFINET, EtherNet/IP, Modbus/TCP) that is compatible with your control system. Next, determine the signal type you require, such as digital input/output (DI/DO), analog input (AI), or relay output. Then, decide whether a single-slot or dual-slot base is more suitable—dual-slot bases allow flexible combinations like digital + analog signals. Finally, choose the right terminal type (three-in-one European terminal, single-row European terminal, or E-CON connector) for easy wiring and maintenance. By carefully considering these factors, you can customize the perfect RS IO module to optimize performance and efficiency in your industrial automation system.
