REOVIB MFS 268-8A-IP54 Frequency Converter – Precision Vibratory Feeder Controller | MFS 26BUL Platform
Engineering Background: The REOVIB MFS 268 series is engineered by MFS (Maschinenfabrik Sievert), a German specialist in vibratory conveying and feeding technology. The MFS 26BUL platform represents the industrial-grade line designed for continuous-duty environments where amplitude stability and electromagnetic compatibility are non-negotiable. The MFS 268-8A-IP54 is the field-hardened variant, rated IP54 for dust and splash resistance, making it the preferred choice for open-floor automation cells.
Product Positioning: This unit serves as the dedicated frequency converter and amplitude controller for electromagnetic vibratory feeders and bowl feeders. It replaces legacy thyristor-based half-wave controllers with a full-wave, phase-angle controlled output that delivers smoother, more consistent part flow — directly reducing jamming rates and improving downstream assembly throughput. Procurement engineers specify this model when the installation environment involves coolant mist, metal dust, or washdown-adjacent conditions.

System Architecture & Signal Flow
The MFS 268-8A-IP54 sits between the plant power distribution (230 V AC) and the electromagnetic vibratory feeder coil. A PLC analog output (0–10 V DC) connects to the reference input terminal, commanding amplitude setpoint. The controller’s internal phase-angle circuit modulates the AC output accordingly. An optional external potentiometer can serve as a manual override. Status feedback (run/fault) is available via dry-contact relay output for integration into the machine safety circuit or SCADA system.
Typical wiring path: PLC AO → MFS 268 Reference Input → Phase-Angle Controller → Feeder Coil → Vibratory Bowl

Technical FAQ
Q: Is the MFS 268-8A-IP54 compatible with 60 Hz feeder coils?
A: Yes. The output frequency is selectable between 50 Hz and 60 Hz via internal DIP switch, making it suitable for both European and North American feeder coil designs.
Q: Can I control amplitude from a Siemens S7 PLC analog output?
A: Yes. The 0–10 V DC reference input is compatible with standard PLC analog output modules (e.g., Siemens SM 332, Allen-Bradley 1769-OF4). Ensure the AO channel is configured for voltage output mode.
Q: What is the difference between MFS 268-8A-IP54 and MFS 268-8A (without IP54)?
A: The IP54 variant features a sealed enclosure rated for dust ingress protection (IP5x) and water splash protection (IPx4). The non-IP54 version is open-panel mount only, suitable for clean control cabinet installations.
Q: Does this unit support soft-start for the feeder?
A: The MFS 268 series includes a configurable ramp-up time to prevent mechanical shock on feeder startup. Ramp duration is adjustable via internal trimmer.
Q: What replacement parts are available?
A: Konmask.com stocks MFS 26BUL platform accessories. Contact us with your serial number for specific spare part availability.
