Industrial controls DESCRIPTION
The LH1532 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
LH1532 SSRs employ current-limiting circuitry, enabling
them to pass lightning surge testing as per ANSI/TIA-968-B
and other regulatory surge requirements when overvoltage
protection is provided.
