Engineered for high performance, this module supports bidirectional signal conversion, transforming optical signals into electrical RS485 or SPA signals and vice versa. With its robust design, the SPA-ZC21 serves as an essential component in modern power system automation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFunctional Highlights\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eInstallation of the ABB SPA-ZC21 is straightforward, connecting directly to the 9-pin D-type connector on the host device's rear panel. Configuration is user-friendly, utilizing front-panel DIP switches that allow users to easily choose between SPA and RS485 communication modes depending on system requirements. The module also features echo checking functionality, which can be activated through switch settings to optimize performance based on whether the connected device operates as a master or slave unit.\u003c\/p\u003e\n\u003cp\u003eMoreover, the SPA-ZC21 excels in environments plagued by electrical and electromagnetic interference, ensuring reliable data transmission between protection relays and control units even in electrically noisy conditions. Additionally, it includes optional mounting accessories compatible with SACO data communication systems, thereby enhancing its versatility in various applications.\u003c\/p\u003e\n\u003cp\u003eOne of the key benefits of the SPA-ZC21 is its ability to provide electrical isolation between devices while facilitating high-speed data exchange. The module draws power directly through the D-type connector from the host device, eliminating the need for separate power supplies. This simplifies installations and improves overall system reliability.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Data\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel Number:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eSPA-ZC21\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModule Type:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eBus Connection Module\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eABB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCondition:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eBrand New\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e1.22 kg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e24 x 19 x 5.3 cm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHS CODE:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e8537101190\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Origin:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eSweden\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Time:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eIn Stock\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity (MOQ):\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCommunication Modes:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eSPA and RS485\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Type:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e9-pin D-type\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Supply:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eDraws power from host device\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmunity to Interference:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eExceptional electrical and electromagnetic immunity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTypical Applications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe ABB SPA-ZC21 Bus Connection Module is suitable for:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePower substation automation systems where reliable communication is critical.\u003c\/li\u003e\n\u003cli\u003eIntegration in SPACOM protection devices to enhance communication efficiency.\u003c\/li\u003e\n\u003cli\u003eDeployments requiring robust performance in high-voltage environments.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eFAQ\u003c\/strong\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the weight of the SPA-ZC21 Bus Connection Module?\u003c\/strong\u003e\u003cbr\u003eThe SPA-ZC21 weighs 1.22 kg.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the SPA-ZC21?\u003c\/strong\u003e\u003cbr\u003eIts dimensions are 24 x 19 x 5.3 cm.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eWhat communication modes does the SPA-ZC21 support?\u003c\/strong\u003e\u003cbr\u003eThe module supports both SPA and RS485 communication modes.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eHow does the SPA-ZC21 receive power?\u003c\/strong\u003e\u003cbr\u003eIt draws power directly from the host device through the D-type connector.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eIs the SPA-ZC21 resistant to electrical interference?\u003c\/strong\u003e\u003cbr\u003eYes, it features exceptional immunity to electrical and electromagnetic interference.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":53262994243894,"sku":"SPA-ZC21","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/2094\/8534\/files\/abb-spa-zc21-bus-connection-module-a1onrh15mlf.jpg?v=1762918320","url":"https:\/\/www.motrolixtech.com\/products\/abb-spa-zc21-bus-connection-module","provider":"Motrolix","version":"1.0","type":"link"}
