It connects a CompactLogix controller to a remote 1769 Compact I\/O bank over a dedicated serial link, allowing I\/O modules to be located away from the controller without needing a full EtherNet\/IP network. The controller communicates with remote I\/O through the CRL link as if those modules were local — the program addresses their data the same way it addresses local I\/O tags.\u003c\/p\u003e\n\u003cp\u003eThe CRL link predates EtherNet\/IP distributed I\/O in the 1769 world. In new system designs, EtherNet\/IP remote I\/O nodes (FLEX I\/O, POINT I\/O, or remote CompactLogix) typically offer more flexibility and performance. The 1769-CRL1 remains relevant for expanding existing CompactLogix systems where adding an Ethernet infrastructure isn't practical, and for applications where a simple, deterministic dedicated link is preferred over a shared Ethernet network.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e1769-CRL1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePlatform\u003c\/td\u003e\n\u003ctd\u003eCompact I\/O (1769)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFunction\u003c\/td\u003e\n\u003ctd\u003eRemote I\/O link master (CRL link)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Remote I\/O Modules\u003c\/td\u003e\n\u003ctd\u003eUp to 16 per remote bank\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Cable Length\u003c\/td\u003e\n\u003ctd\u003e30 m (CRL cable between master and remote adapter)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication\u003c\/td\u003e\n\u003ctd\u003eDedicated serial CRL link (not EtherNet\/IP)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRemote Adapter Module\u003c\/td\u003e\n\u003ctd\u003eRequires 1769-CRL2 at remote end\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eI\/O Data Update\u003c\/td\u003e\n\u003ctd\u003eSynchronous with controller scan cycle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBackplane Current (5V)\u003c\/td\u003e\n\u003ctd\u003e60 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e0°C to 60°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStandards\u003c\/td\u003e\n\u003ctd\u003eUL 508, CE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003ePhysical Installation\u003c\/h3\u003e\n\u003cp\u003eThe 1769-CRL1 installs in the CompactLogix controller's 1769 expansion bus — it occupies one module slot like any other 1769 I\/O module, but it doesn't contribute local I\/O points. Its function is entirely communication. The CRL cable connector is on the module face; run the shielded CRL cable to the remote end where the 1769-CRL2 adapter begins the remote I\/O bank.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eUse only the designated CRL cable — standard Ethernet or serial cable is not a substitute. The CRL link has specific electrical characteristics that require the specified cable type.\u003c\/li\u003e\n\u003cli\u003eGround the cable shield at one end only to prevent shield ground loops.\u003c\/li\u003e\n\u003cli\u003eThe 1769-ECR end cap is required at the rightmost module of the remote I\/O bank, just as with any other 1769 expansion bank.\u003c\/li\u003e\n\u003cli\u003ePower the remote I\/O bank from a dedicated 24V DC supply local to the remote bank — don't run the remote bank's field power through the CRL cable.

Assign the correct module types to the correct slot positions; mismatches between the physical modules and the software configuration cause CRL communication faults.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eLimitations Worth Knowing Before Specifying\u003c\/h3\u003e\n\u003cp\u003eBefore committing to a CRL-based architecture, a few constraints are worth evaluating against the project requirements:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle remote bank per CRL module:\u003c\/strong\u003e one 1769-CRL1 connects to one remote bank (one 1769-CRL2). For multiple remote banks, multiple CRL master modules are needed — one per bank, each consuming one local I\/O slot.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e30-metre cable maximum:\u003c\/strong\u003e fixed, no extension options. If the installation requires the remote bank to be further than 30 m from the controller, the CRL link is not the right solution.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNo EtherNet\/IP at the remote end:\u003c\/strong\u003e EtherNet\/IP-capable I\/O modules installed in the remote CRL bank do not connect to the EtherNet\/IP network from the remote location — they communicate only through the CRL link. For EtherNet\/IP functionality at a remote location, a proper EtherNet\/IP-based remote I\/O architecture is required.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cp class=\"faq-q\"\u003e\u003cstrong\u003eQ: What module is needed at the remote end of the CRL link?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eThe 1769-CRL2 remote adapter module. It installs at the left end of the remote I\/O bank (where the controller or adapter typically goes in a standard system) and accepts the CRL cable from the 1769-CRL1 master.\u003c\/p\u003e\n\u003cp class=\"faq-q\"\u003e\u003cstrong\u003eQ: Can two CRL links serve two different remote banks from the same CompactLogix controller?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eYes. Install one 1769-CRL1 per remote bank in the local I\/O bus, each connected to its own 1769-CRL2 at its own remote location. Each CRL pair is independent.\u003c\/p\u003e\n\u003cp class=\"faq-q\"\u003e\u003cstrong\u003eQ: Does the CRL remote bank affect the controller's scan time?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eYes. The CRL data transfer is synchronous with the controller scan — adding a remote CRL bank increases the minimum scan time compared to local-only I\/O. For applications with tight scan time requirements, verify the additional CRL communication time is within the application's timing budget.\u003c\/p\u003e\n\u003cp class=\"faq-q\"\u003e\u003cstrong\u003eQ: Can analog modules be included in the remote CRL bank?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eYes. The remote bank can contain any mix of 1769 Compact I\/O modules — digital, analog, specialty. Analog modules in the remote bank update at the same scan-synchronous rate as digital modules.\u003c\/p\u003e","brand":"topsdevice","offers":[{"title":"Default Title","offer_id":42742443638845,"sku":null,"price":81.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0635\/6516\/8701\/files\/1769-CRL1_5_617b8dc7-558d-4287-8ee3-44b4d74b4fe6.jpg?v=1769051965","url":"https:\/\/topsdevice.com\/products\/1769-crl1-new-original-1769crl1-ab-series-a-plc-module","provider":"topsdevice","version":"1.0","type":"link"}
