DESCRIPTION
The LH1533 (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
- Dial pulse
- Ground start
dielectrically isolated technology is comprised of
a
- Ground fault protection
• Instrumentation
• Industrial controls
photodiode array, switch control circuitry, and MOSFET
switches. In addition, the relays 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.
