DESCRIPTION
The LH1526 dual 1 Form A relays are SPST normally open
switches that can replace electromechanical relays in many
applications. The relays require a minimal amount of LED
drive current to operate, making it ideal for battery powered
and power consumption sensitive applications. The relay is
constructed using a GaAIAs LED for actuation control and
MOSFET switches for the output. In addition, the relay
employs current-limiting circuitry to provide overvoltage
protection.
APPLICATIONS
• General telecom switching
• Battery powered switch applications
• Instrumentation
• Industrial controls
AGENCY APPROVALS
• UL1577, file no. E52744
