The VBC-73S Controller, paired with the PET-1 Transducer, is the foundational component of Arthur G. Russell’s VibroBlock Control System for vibratory feeders, operating from a 115 VAC supply. It can be paired with either a 0–3 A or 0–10 A meter, depending on feeder size, to match current-sensing needs. The PET-1 Transducer is required for operation, with vane selections of No. 12 for VB-12L vibrators and No. 16 for VB-16 vibrators to adapt the VibroBlock to the specific vibrator model. The VBC-73S can be used with both 'L' and 'C' VibroBlock Vibrators, and it serves as the controlling core of VibroBlock systems.
