Description

Product Overview The 1TGE120021R0810 is an enhanced ABB MLink communication gateway built for the MNS iS / INSUM intelligent low‑voltage MCC system. It serves as a central data concentrator and protocol bridge, collecting measurement, protection, alarm and SOE data from INSUM motor and feeder units and forwarding it to DCS, SCADA and PLC systems. This variant adds Profibus DP master capability and higher device capacity compared with the basic 1TGE120021R0110.

Differentiation Notes Compared to 1TGE120021R0110, the R0810 version includes native Profibus DP master, supports more motor protection units and larger event storage. It is not a relay or protection unit; it only handles protocol conversion and data aggregation for the MNS iS ecosystem. Original new stock is limited, mostly supplied as surplus or refurbished.
