Description
The X‑412‑I merges four SPST relay outputs with four high‑precision analog inputs into a single, DC‑powered Ethernet I/O PLC. Ideal for applications like water treatment, tank level sensing, lift station monitoring, and grain handling, it offers real‑time relay control and analog data acquisition via its built‑in web server—no software required. Configure conditional and scheduled logic through an intuitive browser interface and integrate easily into IIoT networks.
