7MH4601-1BA01 Siemens SIWAREX U Weighing Electronics, Two-Channel, for SIMATIC S7-300 / ET 200M
The Siemens 7MH4601-1BA01 is SIWAREX U weighing electronics in the two-channel version, designed to connect two scales to a SIMATIC S7-300 controller or an ET 200M distributed I/O station. It plugs into the S7 system like a standard module and brings load cell measurement straight into the automation system. It is used for level measurement in silos and hoppers, platform and container scales, and crane or belt load monitoring. An RS232 interface for PC connection and a TTY interface for a remote display are integrated, and the bus connector is included.
