The RADWAG MW series are purpose-built PROFIBUS DP mass converters that bridge the gap between a strain-gauge load cell platform and a PROFIBUS-based PLC control system. Rather than routing the raw millivolt load cell signal through a separate weight transmitter, then through an analog input card, and then through a PLC scaling function — with the accuracy losses at each conversion stage — the MW module digitizes the load cell signal at source, applies OIML Class III legal-for-trade processing (10,000 verification units, multi-range capable), and delivers the validated net weight directly to the PROFIBUS master as a cyclic data exchange variable. The M12 5-pin B-coded connectors (IN + OUT) use standard DP PROFIBUS physical layer wiring with integrated 5V terminator voltage.

How do the three MW series models address different applications?

The MW-01 is the compact workhorse: a single-platform weighing module in an IP66 metal housing, powered from 8–30V DC, with 2 inputs and 3 outputs (reed relay + fast transistor) for simple checkweighing and filling valve control — designed for mounting directly at the scale location with short load cell cable runs. The MW-01-A4 adds a mains-powered option (100–240V AC) in an IP66 aluminum enclosure suitable for panel mounting in a control cabinet, with OIML Class II capability for higher-precision applications. The MW-04 scales to 2–4 independent weighing platforms from a single PROFIBUS node, with 4 OptoMOS inputs and outputs, IP65 protection, and an internal resolution of 8,388,608 divisions — positioned for multi-scale dosing and blending systems where a single PROFIBUS drop must report weights from ingredient hoppers, a mixing vessel, and a discharge conveyor simultaneously.
