PD4-6600 Loop Leader And Large Display Loop-Powered Process Meter
Brand: Precision Digital CorporationThe PD4 is available in two configurations: Display only and with two solid-state relays and 4-20 mA analog output. All models come equipped with two open collector outputs and remote contacts.
The open collector outputs are useful for alarm indication. The remote contacts can be used to remotely operate the four programming buttons, to acknowledge the relays, to start/stop a timer/stopwatch, and more.
The relays can be programmed for alarm indication, on/off control, or pump alternation.
Finally, there are intrinsically safe versions of these instruments that can be installed in hazardous areas.
