It supports up to 16 I\/O modules across as many as three I\/O banks, using up to two expansion cables to extend the local bus, and accepts an optional CompactFlash card for non-volatile program storage.\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-L32E\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUser Memory\u003c\/td\u003e\n\u003ctd\u003e750 KB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication\u003c\/td\u003e\n\u003ctd\u003e1 × EtherNet\/IP, 1 × RS-232 (DF1, DH-485, ASCII)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax I\/O Modules\u003c\/td\u003e\n\u003ctd\u003e16\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax I\/O Banks\u003c\/td\u003e\n\u003ctd\u003e3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Supply Distance Rating\u003c\/td\u003e\n\u003ctd\u003e4 modules\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBackplane Current\u003c\/td\u003e\n\u003ctd\u003e660 mA @ 5V, 90 mA @ 24V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Dissipation\u003c\/td\u003e\n\u003ctd\u003e~4.7 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIsolation Voltage\u003c\/td\u003e\n\u003ctd\u003e30V continuous, basic insulation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOptional Flash Memory\u003c\/td\u003e\n\u003ctd\u003e1784-CF128 CompactFlash\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery\u003c\/td\u003e\n\u003ctd\u003e1769-BA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eAn Early Step Into Ethernet-Based Control\u003c\/h3\u003e\n\u003cp\u003eThis controller occupies a specific historical and functional niche: it was among the earlier modular controllers in its broader product family to add a built-in EtherNet\/IP port, providing a migration path for facilities moving from older serial-based controller architectures toward Ethernet-native networking without jumping straight to a larger, more expensive platform. The single Ethernet port handles programming, I\/O messaging, and general network communication — sufficient for installations with one controller and a handful of network-connected devices, though without the dual-port ring topology support found on later controller generations.\u003c\/p\u003e\n\u003cp\u003eThe 16-module, 3-bank expansion capacity using up to two expansion cables gives this controller meaningful I\/O reach for a mid-sized machine or process cell, distributing modules across physically separate locations within the rated cable distance rather than requiring everything to sit immediately adjacent to the controller.\u003c\/p\u003e\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cp class=\"faq-q\"\u003e\u003cstrong\u003eQ: Does this controller support dual-port Ethernet for ring topology?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eNo. It has a single Ethernet port, supporting star or linear topology only — ring participation with automatic fault rerouting requires a controller generation with dual Ethernet ports.\u003c\/p\u003e\n\u003cp class=\"faq-q\"\u003e\u003cstrong\u003eQ: Can the RS-232 port and EtherNet\/IP port be used simultaneously for different purposes?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eYes. The serial port can connect to a legacy device or HMI using DF1, DH-485, or ASCII while the Ethernet port handles programming and network I\/O at the same time, since the two interfaces operate independently.\u003c\/p\u003e\n\u003cp class=\"faq-q\"\u003e\u003cstrong\u003eQ: How many I\/O modules can be installed on each side of the power supply?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eUp to eight modules can be placed on each side of the power supply within the first I\/O bank, with the controller itself required to be the leftmost module in that first bank.\u003c\/p\u003e\n\u003cp class=\"faq-q\"\u003e\u003cstrong\u003eQ: What battery does this controller use, and can a different type be substituted?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eThe 1769-BA battery is the specified replacement — substituting a battery intended for a different controller family is not recommended, since battery chemistry and connector compatibility can differ between platforms.\u003c\/p\u003e","brand":"topsdevice","offers":[{"title":"Default Title","offer_id":42779070693437,"sku":null,"price":1194.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0635\/6516\/8701\/files\/1769-L32E_6.jpg?v=1782370922","url":"https:\/\/topsdevice.com\/products\/1769-l32e-new-origina-1769l32e-ser-ab-controller-module","provider":"topsdevice","version":"1.0","type":"link"}
