GSDT-RSW-21 射頻切換模塊

產品(pin)概述:

GSDT-RSW正(zheng)向(xiang)射(she)(she)(she)(she)頻(pin)(pin)(pin)(pin)切換(huan)(huan)(huan)(huan)開關(guan)是一個射(she)(she)(she)(she)頻(pin)(pin)(pin)(pin)轉換(huan)(huan)(huan)(huan)模(mo)(mo)塊。當主(zhu)(zhu)(zhu)(zhu)射(she)(she)(she)(she)頻(pin)(pin)(pin)(pin)通(tong)(tong)(tong)道(dao)(dao)(dao)(dao)(dao)信(xin)(xin)號(hao)斷(duan)開時,模(mo)(mo)塊會自動將主(zhu)(zhu)(zhu)(zhu)射(she)(she)(she)(she)頻(pin)(pin)(pin)(pin)信(xin)(xin)號(hao)切換(huan)(huan)(huan)(huan)到(dao)副射(she)(she)(she)(she)頻(pin)(pin)(pin)(pin)通(tong)(tong)(tong)道(dao)(dao)(dao)(dao)(dao)。模(mo)(mo)塊具有閾值(zhi)(zhi)設(she)置(zhi)功能,可以根據閥值(zhi)(zhi)來確定(ding)何時進行(xing)切換(huan)(huan)(huan)(huan)。如(ru)果設(she)置(zhi)工作通(tong)(tong)(tong)道(dao)(dao)(dao)(dao)(dao)在主(zhu)(zhu)(zhu)(zhu)射(she)(she)(she)(she)頻(pin)(pin)(pin)(pin)通(tong)(tong)(tong)道(dao)(dao)(dao)(dao)(dao),主(zhu)(zhu)(zhu)(zhu)通(tong)(tong)(tong)道(dao)(dao)(dao)(dao)(dao)信(xin)(xin)號(hao)工作在閾值(zhi)(zhi)范圍外(wai),會自動切換(huan)(huan)(huan)(huan)到(dao)副射(she)(she)(she)(she)頻(pin)(pin)(pin)(pin)通(tong)(tong)(tong)道(dao)(dao)(dao)(dao)(dao),當主(zhu)(zhu)(zhu)(zhu)射(she)(she)(she)(she)頻(pin)(pin)(pin)(pin)通(tong)(tong)(tong)道(dao)(dao)(dao)(dao)(dao)信(xin)(xin)號(hao)恢復(fu)到(dao)閾值(zhi)(zhi)范圍內, 則信(xin)(xin)號(hao)會從副射(she)(she)(she)(she)頻(pin)(pin)(pin)(pin)通(tong)(tong)(tong)道(dao)(dao)(dao)(dao)(dao)切換(huan)(huan)(huan)(huan)到(dao)主(zhu)(zhu)(zhu)(zhu)射(she)(she)(she)(she)頻(pin)(pin)(pin)(pin)通(tong)(tong)(tong)道(dao)(dao)(dao)(dao)(dao);如(ru)果兩(liang)射(she)(she)(she)(she)頻(pin)(pin)(pin)(pin)通(tong)(tong)(tong)道(dao)(dao)(dao)(dao)(dao)信(xin)(xin)號(hao)都在閾值(zhi)(zhi)范圍外(wai),則自動換(huan)(huan)(huan)(huan)回(hui)主(zhu)(zhu)(zhu)(zhu)射(she)(she)(she)(she)頻(pin)(pin)(pin)(pin)通(tong)(tong)(tong)道(dao)(dao)(dao)(dao)(dao)。無論主(zhu)(zhu)(zhu)(zhu)射(she)(she)(she)(she)頻(pin)(pin)(pin)(pin)通(tong)(tong)(tong)道(dao)(dao)(dao)(dao)(dao)或(huo)副射(she)(she)(she)(she)頻(pin)(pin)(pin)(pin)通(tong)(tong)(tong)道(dao)(dao)(dao)(dao)(dao)的輸入電平低于預設(she)值(zhi)(zhi)時都會有報警(jing)顯示。
