The PD690 is a high performance, easy to use, industrial-grade microprocessor-based digital process meter. It accepts all standard process signals (4-20 mA, 1-5 V, & 0-10 V) and displays these signals in engineering units on a 4½ digit display. The display includes an extra zero, which may be used to handle numbers up to 199,990. The meter also provides 24 VDC to power the transmitter. Options include 2 or 4 relays and an Isolated 4-20 mA Transmitter Output.
