PD8-6300 ProtEX-MAX Explosion-Proof Pulse Input Flow Rate/Totalizer


The ProtEX-MAX™ PD8-6300 offers all the functionality of the ProVu PD6300 as a fully FM, CSA, ATEX, and IECEx approved explosion-proof product. It is specifically designed to display flow rate and total from a pulse output (NPN, PNP, TTL, switch contact, sine wave, etc.) flowmeter. It displays that signal on a dual-line, 6-digit Sunbright sunlight readable display. Flow rate is typically displayed on the upper line and the cumulative total is displayed on the lower line. The total overflow feature allows up to a 9-digit total and grand total to be displayed. The PD8-6300 includes a 24 VDC power supply to drive the flowmeter and can be equipped with up to four internal relays and a 4-20 mA analog output. It can be programmed and operated without opening the housing by using the built-in SafeTouch® through-glass buttons or the RS485 serial communication port with free Modbus® protocol.
