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. Both the SSR and optocoupler provide 5300 VRMS of input to output isolation.
