This simple wall, or in some cases, flowmeter mounted instrument gives
an adjustable set point with a single pole, voltage free relay
output. There are two hysterisis levels to prevent relay flutter
at the selected set frequency input. The standard converter has
an input frequency range of 0.5 to 5 KHz. Four operating ranges
are selectable via a pair of DIL switches these are nominally
:- 100, 500 1000 and 5000 Hertz. A special lower range version
is available for use with lower frequency inputs such as positive
displacement flowmeters, this device operates down to 0.25 Hz.
The status LED on the circuit board indicates when the relay has
operated. The enclosure is a high impact polycarbonate that seals
the unit to IP65 (NEMA 4X). Access to the terminals is normally
via a pair of glands on the bottom of the enclosure.
