一、產(chǎn)品介紹

SRDX系列信號(hào)繼電器適用于直流操作的保護(hù)和自動(dòng)控制裝置中，作為動(dòng)作指示信號(hào)使用。此信號(hào)繼電器

動(dòng)作速度快;電流動(dòng)作范圍寬;防震性好;既能手動(dòng)復(fù)位也能遠(yuǎn)程電動(dòng)復(fù)位。

SRDX series of signal relays serve as action signals in protection of AC controlled operationand automation devices.This type of relays is characterized by quick action, wide range of current actionand high shake proof performance, and it can be either reset by hand or by remote electric control.
