1.Product Overview
The Murr Elektronik 56526 MICO-Link IO-Link Master is a rugged communication hub designed to bridge conventional I/O with Industry 4.0 networks. Housed in a compact IP67-rated polymer enclosure, this device integrates 8 configurable IO-Link ports with dual Ethernet protocols (PROFINET and EtherNet/IP) for seamless PLC connectivity. Engineered for harsh environments (-25°C to +70°C), its vibration-resistant design (15g tested per EN 60068-2-6) withstands shocks in mobile machinery and heavy industrial settings. The embedded web server enables browser-based configuration without PLC programming, while M12 connectors ensure reliable field connectivity in dusty/wet conditions. Ideal for decentralizing control architectures while maintaining deterministic data exchange.
