Tower Light Monitor
Potomac Instrument's 1750-TLM can help you meet requirements for tower
light monitoring safely and effectively.
Designed with the Broadcaster in mind the 1750-TLM provides built
in flexibility to simplify even the most complicated installations.
It can even alarm for single bulb failures on towers with Beacons
and Obstruction lights on a single circuit. Status oututs eliminate
the worry of operator interpretation and provide definitive Good-Bad
indications for the operator and your logging equipment. Don't let
tower light failures expose you to increased liability, the 1750-TLM
is compatible with most existing control equipment and may well provide
your best return on investment this year!
||Four comparators each with an adjustable
dc reference voltage and an output open-drain MOSFET which can be
turned on or off when the input voltage goes below or above the reference.
Each input incorporates a detector for an AC input from tower lighting
current sampling transformers.
||+50V max., 100 mA max., 0.3 w max.
||0-3V AC rms max., (0-7.5V dc max.)
||On board circuitry for combining detected
conditions with logic "OR" or logic "AND" functions. Incorporates
one external input to allow "Daisy Chaining" of logic outputs from

||Simpson current sample transformer:
Mdl 186, Cat. #01321 Rated for currents to 50 Amperes.
Maryland Torroid current sample transformer: Mdl 12525 Flexible for
a wide range of currents by selecting the turns of primary wire applied
and the terminating resister used.
