LH1529AB
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 while optocoupler performs ring detection and loop current sensing functions.
