最多8個(gè)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(gè)獨(dú)立的PID控制電路?；締卧獦?biāo)配4個(gè)熱電偶或3個(gè)RTD輸入通道。如果需要，可以購(gòu)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(gè)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(gè)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(gè)控制回路將有兩個(gè)輸出和一個(gè)輸入。輸出可配置為雙回路控制或控制回路和報(bào)警。每個(gè)控制回路的兩個(gè)輸出之一必須是繼電器或脈沖電壓輸出。
