DESCRIPTION
The LH1520 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 MOSFET switches for the output. In addition, the LH1520 SSRs employ current-limiting circuitry to provide overvoltage protection.
