電路使用ADM3485E收發(fā)器，是經(jīng)過驗證并測試的電磁兼容性(EMC)解決方案，可為使用廣泛的RS-485通信端口提供三重保護(hù)。每個解決方案都經(jīng)過測試和特性表征，確保收發(fā)器和保護(hù)電路元件之間的動態(tài)交互能夠協(xié)同工作，保護(hù)它們免遭靜電放電(ESD)、電快速瞬變脈沖群 (EFT)和電涌的破壞——分別由IEC 61000-4-2、IEC 61000-4-4 和IEC 61000-4-5標(biāo)準(zhǔn)定義。本電路使用ADM3485E提供經(jīng)過驗證的RS-485接口ESD、EFT和電涌(常見于惡劣工作環(huán)境) 保護(hù)。
