最多8個控制回路，可選顯示
SCD-8系列多回路DIN導(dǎo)軌安裝溫度控制器可用于控制多達(dá)8個獨立的PID控制電路。基本單元標(biāo)配4個熱電偶或3個RTD輸入通道。如果需要，可以購買額外的輸入卡，但額外的輸入必須與基本單元附帶的輸入類型相同。如果需要8個以上的回路或混合輸入類型，則可以添加SCD-2000從屬模塊，而無需連接額外的電源或通信電纜。
每個回路可以通過標(biāo)準(zhǔn)RS-485串行通信或可選的插入式LED顯示模塊進(jìn)行編程。每個控制回路將有兩個輸出和一個輸入。輸出可配置為雙回路控制或控制回路和報警。每個控制回路的兩個輸出之一必須是繼電器或脈沖電壓輸出。
