LH1529 - OPTICALLY COUPLED TELECOM SWITCH

Description

The LH1529 Telecom switch consists of an optically coupled solid state relay (SSR) and a bidirectional input optocoupler.

The SSR is ideal for performing switchhook and dial-pulse switching while the optocoupler performs ring detection and loop current sensing functions.
