Schneider Electric 171CBU98090 Modicon Momentum CPU Module

Schneider Electric 171CBU98090 Unity M1E processor is the Modicon Momentum CPU module that consolidates USB, I/O bus, RS232/485 serial ports, and 10/100 Mbps Ethernet in a compact IP20 monoblock package for Momentum control systems. This Unity M1E CPU serves as the central controller in Momentum architectures, running Unity Pro software for programming and configuration while exposing built‑in web services that report CPU status, Ethernet statistics, bandwidth usage, and device properties via a web page. With an onboard USB interface and the I/O bus for Momentum I/O modules, it enables local maintenance and remote communications across standard Ethernet networks. Part of Schneider Electric's Modicon Momentum family, it is designed for indoor cabinet installations (IP20) and supports RS232/485 serial links alongside modern Ethernet‑based connectivity, making it suitable for small‑ to mid‑size Momentum installations requiring compact, reliable control with easy diagnostics and web‑based monitoring.
