ADAM-4013
內(nèi)置看門(mén)狗計(jì)時(shí)器
絕緣電壓 3000伏直流電
采樣率：10樣本/秒
精度：+ / - 0.1%或更高模擬量輸入模塊使用微處理器控制整合A/D轉(zhuǎn)換芯片，將電壓、電流、熱電偶或者熱電阻信號(hào)轉(zhuǎn)化為數(shù)字量信號(hào)。然后根據(jù) 模塊的設(shè)置將數(shù)字量表示為工程單位、16進(jìn)制格式或者滿量程的百分比。當(dāng)主機(jī)請(qǐng)求的時(shí)候，數(shù)據(jù)通過(guò) RS-485 界面?zhèn)鬏?。模擬量輸入模塊提供信號(hào)調(diào)理、A/D轉(zhuǎn)換、量程轉(zhuǎn)化和 RS-485數(shù)字通訊功能。通過(guò)提供 A/D輸入光偶隔離和高達(dá)3000V的變壓器隔離，模塊可以保護(hù)用戶設(shè)備免受接地環(huán)流和電源浪涌的危害。
