Siemens SIWAREX WP231 7MH4960-2AA01 Weighing Module 1-Channel 4DI 4DQ Ethernet RS485

Product Description

The Siemens 7MH4960-2AA01 SIWAREX WP231 is a single-channel weighing module designed for SIMATIC S7-1200 systems or stand-alone operation. It is intended for platform and hopper scales using analog strain-gauge load cells with full-bridge technology and supports legal-for-trade weighing applications subject to local verification requirements. The module provides four digital inputs, four digital outputs, one analog output, an RS485 interface, an Ethernet interface, and a dedicated load-cell connection supporting 1 to 4 mV/V signals. Its integrated communication and I/O capabilities make it suitable for industrial weighing, filling, monitoring, and process automation systems where accurate weight acquisition and flexible system integration are required.

Standard Features
