Omron W4S1-03B W4S1 Industrial Switching Hub

Description

Engineered for reliable network performance at the field level, the W4S1-03B industrial switching hub provides robust Ethernet connectivity in demanding factory automation environments. This compact, 3-port unmanaged switch supports fast Ethernet speeds (10BASE-T/100BASE-TX) and is optimized for direct integration with PLCs, HMIs, and distributed I/O systems.

The device ensures stable packet transmission using an internal 80 KB buffer capacity and accommodates up to 2,000 MAC address entries. Designed with industrial-grade resilience, it features a low power consumption profile and comes supplied with a dedicated power supply connector for secure 24 VDC wiring.

Features

• Compact 3-port layout designed for high-density space-constrained control panels.
• Full compatibility with IEEE 802.3 (10BASE-T) and IEEE 802.3u (100BASE-TX) Ethernet standards.
• Integrated 80 KB packet buffer to minimize data frame loss during peak traffic.
• Support for up to 2,000 MAC addresses.
• Supplied with a dedicated terminal connector for stable power distribution.

Applications

• Factory automation and control systems networking.
• Fieldbus and machine-level Ethernet distribution.
• PLC-to-HMI communications.
• Compact control panel integration.

Installation Guidelines

• Mounting: Install within a clean, dry, and dust-free control cabinet. Ensure sufficient spacing around the module vents to facilitate heat dissipation.
• Wiring: Always use shielded twisted-pair (STP) Ethernet cables (Category 5 or higher) to mitigate electromagnetic interference (EMI) in industrial zones.
• Power Input: Use the supplied power supply connector to secure the 24 VDC source, maintaining the strict plus/minus 5% voltage tolerance window.
