1750-TLM
Tower Light Monitor
1750-TLM 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!

1750-TLM SPECIFICATIONS
Configuration 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.
Output Limits +50V max., 100 mA max., 0.3 w max.
Input Range 0-3V AC rms max., (0-7.5V dc max.)
Logic 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 multiple units.
