Taipei, Taiwan – CTC Union Technologies today announced the launch of the IGR-A804SM Series, a new generation of cyber-hardened Layer 3 managed PoE Ethernet switches designed to meet the growing demands of industrial automation, intelligent transportation systems, critical infrastructure, military communications, and utility networks.
As industrial networks continue to converge with IT systems, organizations require networking solutions that provide not only reliable connectivity but also robust cybersecurity protection. Developed following secure-by-design principles aligned with IEC 62443 cybersecurity practices, the IGR-A804SM Series helps operators strengthen network resilience while supporting modern Industrial IoT applications.
The IGR-A804SM Series features 8 Gigabit IEEE 802.3af/at PoE+ ports, delivering up to 30W per port to power IP cameras, wireless access points, industrial controllers, sensors, and other edge devices. In addition, 4 x 100M/1G/2.5G SFP slots provide flexible fiber uplink options for long-distance transmission and high-bandwidth network aggregation.
As a Layer 3 managed switch, the IGR-A804SM Series supports advanced routing capabilities that enable efficient traffic management, network segmentation, and scalable deployment across distributed industrial infrastructures. Layer 3 functionality is increasingly important in large-scale industrial, transportation, and utility networks where performance, security, and network availability are critical.
Built for harsh operating environments, the switch incorporates a fanless design, high MTBF architecture, 4KV surge protection, wide-temperature operation, and dual 48VDC redundant power inputs to ensure continuous operation in demanding field conditions.
