PD655 Plastic NEMA 4X Process Meter With 1.0" Display
Manufacturer: Precision DigitalThe PD655 is a large display, analog input process meter with flow rate/totalizer and batch control capabilities housed in a rugged, impact-resistant, glass-filled, polycarbonate NEMA 4X enclosure.
Each accepts the common process signals such as 4-20 mA, 0-5 VDC, 1-5 VDC and 0-10 VDC and displays these signals in engineering units on a large, high efficiency, 4 1/2 digit LED display.
The meter also provide two isolated 24 V power supplies to drive both the input and output loops. Options include up to 4 relays for alarm or batch control and an isolated 4-20 mA transmitter output.
- 4-20 mA, 1-5 V, 0-5 V, 0-10 V inputs
- 4-1/2 digit + extra zero display for rate
- 6 digit display for total
- Programmable exponent for weirs & flumes
- Pump alternation control
- Two 24 VDC transmitter power supplies
- 200 mA transmitter power supply option
- 2 or 4 relays & 4-20 mA output options
- 115 VAC or 230 VAC power
- Operating temperature: -20 to 65°C
- Pump Alternation (PD655 & PD656 Only)
- Built-in snubbers on each relay contact
- Any set point programmable for process/rate or total
