產(chǎn)品介紹

一、技術(shù)參數(shù)：

類別

DH48S-S(雙設(shè)定.多段式預(yù)置型限時(shí)繼電器)

型號	DH48S-S/1Z	DH48S-S/2Z
延時(shí)基數(shù)	0.01sec、0.01sec、1sec、0.1min、1min、0.1HR、1HR、10HR(任意設(shè)定兩種)
延時(shí)范圍	1-99倍限時(shí)倍率
額定工作電壓	85-265VAC/VDC自由輸入，其他工作電壓可控制
消耗功率	小于4.5W
觸點(diǎn)數(shù)量	1組繼電器，1+3為復(fù)位，1+4為暫停	2組繼電器
觸點(diǎn)容量	阻性負(fù)載：5A/250VAC或5/28VDC最大
顯示方式	固定秒閃指示燈，相應(yīng)的兩位LED顯示前吸合或釋放時(shí)間
精確度	電壓影響誤差、重復(fù)誤差小于±50PPM，預(yù)置誤差為0
信號輸入	復(fù)位和暫停信號輸入為觸點(diǎn)或NPN（發(fā)射極對公共端1）采用光耦隔離，信號寬度不少于0.02Sec	底部無復(fù)位，暫停信號引入
使用環(huán)境	環(huán)境溫度：-10℃-+55℃(不結(jié)冰)，濕度：35-85%HR
抗干擾能力	AC2kV(操作電端之間)或DC±500V，脈沖寬度1μs擾動(dòng)下繼電器正常工作
