The ZLAN category encompasses products related to industrial automation and control systems, particularly those leveraging Ethernet-based communication for seamless device integration. Key offerings include ZLAN serial servers (e.g., ZLAN-5100, ZLAN-8100) for converting RS-232/485 to TCP/IP, IoT gateways with protocol conversion capabilities, and ruggedized Ethernet switches designed for harsh environments. These solutions feature real-time data transmission, remote configuration via web interfaces, and support for industrial protocols like Modbus TCP. Typical applications involve factory automation, SCADA systems, and equipment monitoring, where reliable network connectivity and low-latency communication are critical.
