Siemens 7MH4960-2AA01 Weighing Module for SIWAREX WP231

The Siemens 7MH4960-2AA01 is a single-channel SIWAREX WP231 weighing module designed for SIMATIC S7-1200 or stand-alone operation. It is intended for NAWI (non-automatic weighing instruments) and legal-for-trade applications, supporting platform and hopper scales that use analog load cells in the full-bridge range of 1–4 mV/V. The module provides 4 digital inputs and 4 digital outputs, plus one analog output and a dedicated load-cell interface (LC) for reliable bridge-sensor connections. For communication, it offers Ethernet and RS-485 ports, enabling straightforward integration with PLCs or external control networks. This compact WP231 unit is designed to work with SIMATIC S7-1200 controllers or can operate as a standalone weighing device, delivering precise weight data from a connected load cell to your control system while offering flexible networking and onboard I/O to support common weighing tasks such as batching, inventory management, and process weighing.
