Unlike standard I\/O modules, it integrates an on-board logic processor capable of executing Boolean expressions (AND, OR, XOR, or NONE) with an ultra-fast closed-loop response time of 1 microsecond. This architecture makes the 1769-BOOLEAN ideal for time-critical applications where the main controller scan time is insufficient to react to fast-changing field signals.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr class=\"firstRow\"\u003e\n\u003cth\u003eItem\u003c\/th\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule Identifier\u003c\/td\u003e\n\u003ctd\u003e1769-BOOLEAN\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions (W × H × D)\u003c\/td\u003e\n\u003ctd\u003e35 × 118 × 85 mm \u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.17 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eLogic and Control Architecture\u003c\/h3\u003e\n\u003cp\u003eThe 1769-BOOLEAN evaluates real-time physical inputs as well as virtual inputs received from the backplane. When a configured Boolean expression evaluates to TRUE, the associated output transitions to the ON state immediately, bypassing the standard Requested Packet Interval (RPI) processing of the controller. This hardware-level execution ensures deterministic performance suitable for safety interlocks, high-speed sorting, pulse detection, and similar ultra-fast control tasks.\u003c\/p\u003e\n\u003ch3\u003eComparison of Boolean Operations\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eAND\u003c\/strong\u003e: Output is energized only when all specified input conditions are TRUE.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eOR\u003c\/strong\u003e: Output is energized when any one of the specified input conditions is TRUE.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eXOR\u003c\/strong\u003e: Output is energized only when an odd number of inputs are TRUE (exclusive OR).\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eNONE\u003c\/strong\u003e: Output is controlled directly by the user program, operating as standard discrete I\/O.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCommon Technical Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eCan this module be used without a CompactLogix CPU?\u003c\/strong\u003e\u003cbr\u003eNo. Although the 1769-BOOLEAN performs logic processing internally, it must be installed in a CompactLogix local rack or a distributed I\/O system (such as a 1769-AENTR) to receive configuration data and operating power from the backplane.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the advantage of sourcing outputs on this module?\u003c\/strong\u003e\u003cbr\u003eSourcing outputs supply the positive voltage (+) to the load.
