APPLICATIONS * General Telecom Switching - On/off Hook Control - Ring Delay - Dial Pulse - Ground Start - Ground Fault Protection * Instrumentation * Industrial Controls DESCRIPTION The LH1522 dual 1 Form A relays are SPST normally open switches that can replace electromechanical relays in many applications. They are constructed using a GaAIAs LED for actuation control and an integrated monolithic die for the switch output. The die, fabricated in a high-voltage dielectrically isolated technology is comprised of a photodiode array, switch control circuitry, and MOSFET switches. In addition, the LH1522 SSRs employ current-limiting circuitry, enabling them to pass FCC 68.302 and other regulatory surge requirements when overvoltage protection is provided. 4 typ. .050 (1.27) typ. .268 (6.81) .255 (6.48) .390 (9.91) .379 (9.63) .031 (.79) typ. .150 (3.81) .130 (3.30) .395 (10.03) .375 (9.52) .312 (7.80) .298 (7.52) 3 to 7 .045 (1.14) .030 (0.78) Radius .008 (.25) .004 (.10) .040 (1.02) .020 (.51) .100 (2.54) typ. 10 .315 (8.00) typ. .010 (2.54) typ.
