KL6781
The KL6781 from Beckhoff is a lightweight 60-gram analog input module and supports M-Bus physics with up to 40 standard loads across industrial environments. As part of the KL Analog Input Modules series, it provides master-slave bus access via polling and offers a default data transfer rate of 2400 baud over reliable TwinCAT PLC integration.
It features 500 V electrical isolation between K-Bus and M-Bus and complies with EMC immunity and emission standards EN 61000-6-2 and EN 61000-6-4, operating reliably within an ambient temperature range of 0 °C to +55 °C. The module draws a maximum current of 250 mA and mounts on a 35 mm rail with IP20 protection.
