LH1529AAC

LH 系列 350 V 0.12 A 20 Ohm 双通道 固态继电器

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 5300 VRMS.
