The W4S1 Switching Hub from OMRON is a low-cost, unmanaged switch that does not require software settings to maintain superior reliability and consistent control data performance on an Ethernet/IP network. It can be used with confidence because it carries a brand name well known at production sites and because it is backed by OMRON's total support package for products ranging from PLCs to switching hubs.
Components & Accessories
Industrial Switching Hubs OMRON W4S1
Provides the environmental resistance and functionality required in factory automation built around Industrial Ethernet communications.
Features
Environmentally Resistant and Highly Reliable Ethernet Communications for Production Sites
[Environmentally Resistant] Perfect Fit for Factory Automation Environments
Tough environmental resistance assures users that the W4S1 Switching Hub can perform in any environment where PLCs and robots are found. Add to this simple DIN track mounting and well-thought out cable mounting angles and the result is a significant reduction in the man-hours and space requirements for control panel installation.
[Highly Reliable] Enhanced Network Reliability
The W4S1 Switching Hub is an unmanaged switch that is fully capable of failure detection and broadcast storm detection. It improves network reliability by notifying users immediately via contact outputs and LED indicators when an error occurs to quickly pinpoint the location of the error.
Failure Notification
LED indicators and external outputs notify users when an SW-LSI or microcomputer error has occurred.
Broadcast Storm Detection and Suppression
The W4S1 Switching Hub detects and suppresses broadcast storms that occur when switches are accidentally connected in a loop.
[Full Line of Products] The 3- or 5-port Product Variation Ensures the Right Product Choice
We offer a low-cost 3-port model that can be used as easily as a T-branch to let you select the best model for your application.
[Maintaining EtherNet/IP Performance] Quality of Service (QoS) without Support Software
The QoS (packet prioritization control) for EtherNet/IP ensures high-speed delivery of control data even if it is dispersed among images and similar data-intensive applications. And complex software settings are eliminated because QoS can be enabled with a DIP switch setting.
No Support Software required.
Simply turn ON a DIP switch pin to enable QoS.
