LOCOMOTIVE HEADLAMP INTEGRITY MONITOR

Locomotive headlamp operation is obviously a function of safety in railroad operations. 

Locomotive fault reporting of headlamps can now be made automatic with the fitting or retrofitting of this product.

The 8354 device is designed to be invisible in the electrical characteristic of the headlamp circuit, therefore there is zero reduction of output wattage in bright or dim mode. 

There isn't a requirement to install resistors, LED's, etc. in the lamp's circuitry required by conventional types of headlamp monitoring. Using  volt drop resistors in the lamp circuit can result in an exponential wattage output drop from the filament,  in some cases up to 35 watts. 

The AD 8354 is a 130mm x 68mm x 29mm (overall measurement) enclosure that provides twin inputs for locomotive headlamps. A SPCO (.3amp/100vdc) output is provided to indicate the integrity of the each lamp filament without electrical change to headlight circuits.

The AD 8354-4 provides 4 lamp inputs. Dimensionally: 120mm x 95mm x 55mm
