The ProtEX-MAX™ PD8-6310 offers all the functionality of the ProVu PD6310 as a fully FM, CSA, ATEX, and IECEx approved explosion-proof product. It is a 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 convenient SafeTouch^® through-glass buttons for simple operation and menu navigation without having to remove the cover. The preclose deactivates a specific relay 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. The PD8-6310 includes a 24 VDC power supply to drive the flowmeter and can be equipped with four internal relays and a 4-20 mA analog output.
