ZLAN5143I是上海卓岚信息科技(ji)有限(xian)公司设计的(de)(de)一款专门为抗(kang)雷(lei)击、抗(kang)电磁干扰(rao)、抵抗(kang)恶(e)劣环境要求(qiu)而设计的(de)(de)一款高可靠性(xing)、高性(xing)能串(chuan)口服(fu)务器/Modbus网关产(chan)品，是串(chuan)口服(fu)务器的(de)(de)旗舰级产(chan)品。可以应(ying)用于隧道监(jian)控(kong)、风力发电、野外(wai)地(di)质灾害监(jian)控(kong)等需(xu)要抗(kang)干扰(rao)、抗(kang)雷(lei)击的(de)(de)工业(ye)应(ying)用场合。

ZLAN5143I具有(you)(you)良(liang)好的(de)(de)接(jie)口隔离特性。其RS485/RS422不仅具有(you)(you)正负(fu)15KV的(de)(de)抗静电(dian)(dian)(dian)(dian)干扰，而(er)且具有(you)(you)2500V的(de)(de)接(jie)口隔离，即在(zai)RS485线和(he)外(wai)壳(qiao)之(zhi)间加2500V交流电(dian)(dian)(dian)(dian)压(ya)，漏(lou)电(dian)(dian)(dian)(dian)到(dao)(dao)ZLAN5143I内部电(dian)(dian)(dian)(dian)流小于5mA。 针对某些通过电(dian)(dian)(dian)(dian)源(yuan)雷击烧(shao)毁(hui)串口服务器的(de)(de)问题，ZLAN5143I对电(dian)(dian)(dian)(dian)源(yuan)进行(xing)了隔离设(she)计，采用了3000V隔离电(dian)(dian)(dian)(dian)源(yuan)，即在(zai)输入(ru)电(dian)(dian)(dian)(dian)源(yuan)线和(he)外(wai)壳(qiao)上加3000V交流电(dian)(dian)(dian)(dian)，漏(lou)电(dian)(dian)(dian)(dian)到(dao)(dao)ZLAN5143I内部电(dian)(dian)(dian)(dian)流小于5mA。隔离经(jing)过严格测试。提供外(wai)壳(qiao)接(jie)地端(duan)子，可以将(jiang)雷击电(dian)(dian)(dian)(dian)流释放到(dao)(dao)大地，保护(hu)产品。

ZLAN5143I的RS485具有驱动(dong)256个负载(zai)的能力(li)(li)，和驱动(dong)32个负载(zai)的产品相(xiang)比，可以实(shi)现更多设备数据(ju)监控能力(li)(li)，节约了成本。ZLAN5143I具有RS232/485/422三种接(jie)(jie)口形式(shi)。输(shu)入(ru)电(dian)压可以提供DC Q2.1插(cha)孔或(huo)接(jie)(jie)线端子方式(shi)，输(shu)入(ru)电(dian)压为18～36V（也可以定制12V产品）。可配(pei)备导轨(gui)安装配(pei)件。

ZLAN5143I不仅具(ju)有TCP到RS232/485/422的(de)数(shu)(shu)据(ju)透(tou)传功(gong)能，同时(shi)具(ju)有存(cun)储型Modbus网(wang)关的(de)功(gong)能。其中的(de)存(cun)储型是指(zhi)，5143I可以自动采集(ji)Modbus RTU设(she)备(bei)的(de)数(shu)(shu)据(ju)并存(cun)储起来(lai)，网(wang)口端采集(ji)数(shu)(shu)据(ju)直(zhi)接从5143I内(nei)部(bu)读(du)取(qu)，大大加快(kuai)了网(wang)口端数(shu)(shu)据(ju)的(de)采集(ji)速(su)度。
