Siemens 6BK1622-0AA00-0AA0 SIMATIC PN/M-Bus LINK PROFINET 40-Device Telecontrol Module

The Siemens 6BK1622-0AA00-0AA0 is a SIMATIC PN/M-Bus LINK coupling module that bridges a PROFINET network to an M-Bus field bus, acting as M-Bus master for up to 40 connected meters. It runs on 24 V DC (20.4-28.8 V), has two RJ45 PROFINET ports with an integrated switch, and carries IP20 protection.

Selection Notes

The 40-device M-Bus master capacity and 300 m max cable length size this LINK module for a full sub-metering branch rather than a handful of meters, so count connected M-Bus devices against that 40-unit ceiling before adding more. Two RJ45 ports with an integrated switch let it sit in a PROFINET line topology without a separate switch upstream. It is rated to -25°C on the low end, so verify the installation location's minimum temperature against that limit in unheated cabinets.

Applications

Bridges PROFINET-based automation and building-management systems to M-Bus energy and utility meters for centralized remote metering and consumption monitoring.
