The NM-CCU is a radio network data concentrator capable of connecting outstations to many kinds of SCADA systems. Its current model incorporates the modern GW502-iM gateway and protocol converter.

The NM-CCU 500 monitors the status data from, and sends control signals to, the outstations in a radio communication system for electricity distribution networks. It consists of:

• The GW502-iM gateway and protocol converter
• PDR 300 data radio
• The CCU100S software
• An indoor cabinet
• Optionally, a human–machine interface (HMI) panel with a touch screen.

With the intuitive HMI, the NM-CCU can also be used as an independent data concentrator and/or as a primary SCADA RTU. The NM-CCU cabinet is designed for installation within an enclosed space at a substation or in an office.
