CLAIREX ELECTRONICS DIV Photomods Twelve Volt Modules e Twelve Volt, 40 Ma Lamp e Low Impedance, Long Life Isolation Voltage 2500V PAC e No Moving Parts APPLICATIONS CLM3012A This module is designed for applica- tions where appropriate lamp power is available. Ex- tremely long lamp life may be obtained by lamp- voltage derating without serious sacrifice of the ex- traordinarily wide cell resistance span which the unit offers, Since Ropg exceeds 10% ohms, excellent isola- tion may be achieved in signal commutation circuts.

Even with lamp volt- age derating to virtually infinite lamp life, cell (ON) resistance does not exceed 100 ohms. Applications include low impedance interface switching, remote audio squelch functions, and other such isolated signal shorting circuits.
