Telecom Switch 1 Form A Solid-State Relay

DESCRIPTION

The LH1529A and LH1529B telecom switches consist of an

optically coupled solid state relay (SSR) and bidirectional

input optocoupler. The SSR is ideal for performing switch

hook and dial-pulse switching whilst optocoupler performs

ring detection and loop current sensing functions. Both the

SSR and optocoupler have an isolation test voltage of
