Description

Product Overview The 1TGE120021R0110 is an ABB MLink communication gateway for the MNS iS intelligent low-voltage switchgear system. It acts as an interface between MNS iS motor control / feeder protection units and higher-level DCS, SCADA or plant monitoring systems, delivering protocol conversion, data concentration and remote diagnostics for MCC cabinets. It supports redundant network setup for critical power distribution applications.

Differentiation Notes This gateway is dedicated to the MNS iS low-voltage switchgear ecosystem. It is not a general-purpose PLC CPU; it aggregates data from multiple intelligent feeder and motor protection units. Many part variants within the same 1TGE120021Rxx family differ by protocol set and redundancy capability.
