The limited service life of filament signal lamps often necessitates regular testing, as the indication of a defective lamp may not be immediately recognised. The YWAD lamp test module is a din rail mounted 11 way lamp test module, the extra input terminal “C” is the lamp test input. For more than 11 ways a number of units can be linked together via the “C” input terminal. The lamp test module uses very high voltage tolerant components, such as avalanche diodes. Avalanche diodes are especially suitable for withstanding high voltages.

The YWAD is essentially a diode based device and can be used in both AC and DC applications. However, when used in AC applications the YWAD when activated will pass only a half cycle. This will result with the lamps being approx. 60% bright when the lamps are tested. Whilst this is satisfactory for filament lamps it is usually not sufficient for LED type lamps. For LED lamps use product type YWACD.
