Move discrete signals and relay control into a managed Ethernet environment without redesigning the edge. Perle’s IOLAN DS1 D2R2 is purpose-built for distributed control applications that need reliable Fast Ethernet connectivity, 2 digital I/O points, and 2 relay outputs in a compact device server. The 1.8-inch height and 5-inch depth support installations where space is tight, while the DB9M serial connection helps the unit fit into existing industrial and automation workflows. Compatibility with Linux, Solaris, AIX, SCO Unixware, SCO Openserver, NCR, HPUX, and Microsoft Windows Server 2003, XP, and 2000 makes it practical in mixed operating environments where standardization is not always possible. This model is a strong fit for teams that need a focused I/O endpoint rather than a general-purpose platform. It gives you the control points you need at the edge, with the network access and long-term support profile expected in infrastructure deployments that must stay stable over time.
