7MH4900-3AA01 SIEMENS Exclusive SIWAREX FTC Weighing Module Original Brand New

The SIEMENS 7MH4900-3AA01 is a high-precision SIWAREX FTC single-channel weighing module designed for seamless integration with SIMATIC S7-300 and ET 200M systems. Engineered for continuous weighing applications such as belt scales, loss-in-weight feeders, and solids flowmeters, this original brand new module provides accurate and consistent weight and force measurement through analog load cells and strain gauges (full bridges).

This compact and flexible module supports 7 digital inputs, 1 counter input, 8 digital outputs, 1 analog output, RS485 and RS232 interfaces, and a dedicated load cell interface for 1–4mV/V input. Its advanced communication capabilities and compatibility with SIMATIC systems enable real-time diagnostics, easy configuration, and seamless integration into automated industrial environments.

Overview

The SIWAREX FTC (Flexible Technology for Continuous Weighing) is purpose-built for precision measurement in demanding applications. Whether used for force detection, continuous flow monitoring, or weight control, it leverages the full capabilities of SIMATIC S7/PCS 7 automation platforms, including integrated diagnostics, communication, and toolsets for configuration.

Design

SIWAREX FTC is a SIMATIC S7-300 function module that snaps directly onto the S7-300 or ET 200M backplane bus. Its 80 mm-wide design is optimized for easy mounting and wiring.

Key design features include:

• Standard 40-pin front connector for load cells, analog output, and digital I/O
• 9-pin SUB-D interface for PC connectivity (RS232)
• Separate 2-pin connector for power supply
• Complete automation integration for belt scale applications via SIMATIC
