The ProtEX-MAX PD8-6300 offers all the functionality of the ProVu PD6300 as a CSA, ATEX, and IECEx certified explosion-proof product. It is available in an aluminum or stainless steel enclosure and will operate over a wide temperature range of -55 to 65°C (-67 to 149°F). 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 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 RS-485 serial communication port with free Modbus protocol.
