Siemens 7MH4138-6AA00-0BA0 Weighing Electronics Module

The Siemens 7MH4138-6AA00-0BA0 SIWAREX Weighing Module provides precise digital conversion of load-cell signals into weight data for industrial control, making it a core component in batching, dosing, and weighing systems. Designed for DIN rail mounting and backplane bus integration with SIMATIC PLCs, it accepts a load-cell input, performs strain-gauge weight measurement, and includes built-in status and fault diagnostics. Operated from 24 V DC, with IP20 protection and an 0°C to 60°C operating range, it suits manufacturing plants, food processing, chemical industries, and bulk-material handling where accurate weight data is essential; common replacements include Siemens 7MH4960-2AA01.
