presents the new PReview 5725 universal pulse/frequency displays, newly introduced to the PR Electronics display family.
PReview 5725 universal pulse/frequency displays are ideal for a variety of tasks in f/I conversion including measurement, readout, surveillance and control of pulse-based process parameters such as frequency, flow, rotation and speed among others.
Designed for flexibility, easy configuration, quick wiring and relay testing as well as reliable signal conditioning, PReview 5725 is particularly well suited for applications in the marine, chemical and cement industries as well as the energy and machine building segments.
Featuring a universal pulse input and power supply range, PReview 5725 offers an analogue output that gives a programmable response time and two potential free relays with programmable on/off delay.
PReview 5725 can be easily programmed using the three push-buttons on the display front. The scrolling Help text in the display available in 8 languages, will also guide the user during configuration. The configuration is password-protected to prevent unauthorised changes.
Quick wiring and relay test
The cables in the screwless terminals on the display can be quickly connected while the relay test also takes just a few seconds as each relay can be activated and deactivated independently of the input signal.
Reliable signal conditioning
PReview 5725 has been designed according to strict European standards and is approved by UL for installation in the USA and by DNV for use in the marine industry. Power supply, relays and analogue output are galvanically separated by 2.3 kVAC isolation. When the NAMUR input is selected, PReview 5725 can be set for alarm function via the display, relays and/or the analogue output in case of an error in the NAMUR sensor.
The new PReview 5725 universal pulse/frequency displays are backed by PR Electronics’ 5-year product guarantee.
