Precision Digital PD662 3½+ Digit NEMA 4X Loop-Powered Meter

3½+ Digit NEMA 4X Loop-Powered Meter

The PD662 Hatchet NEMA 4X loop-powered meter is perfect for applications where a simple, inexpensive display is required and AC power is not available. That’s because the PD662 derives all its power from the 4-20 mA loop. The PD662 is scaled using four push buttons and can be done without applying an actual calibration signal. The PD662’s display will read up to 2,999; we call this 3½+ digits! The loop-powered backlighting option lets you see the display under any lighting condition and is powered completely from the 4-20 mA loop. This means there is no need for additional wiring and never any batteries to change. The PD662 Hatchet is housed in rugged NEMA 4X enclosure and is provided with one ½ conduit hole. The PD662 is available with an optional 24 VDC powered heater that allows the PD662 to operate in temperatures as low as -55°C.

The PD662 is designed to be easily wired into your current loop and quickly programmed.
