The PD662 NEMA 4X, CSA Certified loop-powered meter is perfect for applications where a simple, inexpensive display is required and AC power is not available. The PD662 derives all its power from the 4-20 mA loop, including its optional backlight feature. It can be easily scaled in the field using four push buttons; with or without applying an actual calibration signal. The PD662’s display will read up to 2999; we call this 3½+ digits! The PD662 is housed in a rugged NEMA 4X enclosure and is provided with one ½” NPT pipe conduit hole.
