The ProVu PD6310 is an 1/8 DIN pulse input (NPN, PNP, TTL, switch contact, sine wave, etc.) digital batch controller specifically designed for single and multi-stage batching applications. 

It provides excellent but simple batch control capabilities with features such as preclose relays and automatic overrun correction for more accurate batches and intuitive front panel buttons for simple operation and menu navigation. 

The preclose deactivates a specific relay on the batch controller before the batch is finished in order to allow slower fill rates and increased accuracy. Automatic overrun correction keeps the batch size accurate over time and with system wear. 

With expansion module relays, up to eight-stage batching is possible; each additional stage-batching relay has an individually programmable preclose amount. 

Like all ProVu meters, the PD6310 batcher includes UL / C-UL listing and CE marking, a NEMA 4X front, and AC or DC power options.
