Operating at a nominal rating of 24 VDC across 8 dedicated output channels, this module controls field devices such as solenoids, relays, indicator lights, and motor starters while providing channel-to-channel electrical isolation to protect control networks against cross-talk and electrical noise.\u003c\/p\u003e\n\u003ch3\u003eChannel Isolation and Output Performance\u003c\/h3\u003e\n\u003cp\u003eDesigned for switching high-density 24 VDC loads, the module provides individual galavanic isolation across its 8 output circuits. This construction prevents ground loops, reduces common-mode voltage disruptions, and ensures reliable operation in demanding industrial environments where field devices operate across separate power sources or distinct potential references.\u003c\/p\u003e\n\u003ch3\u003eChassis Integration and Mechanical Mounting\u003c\/h3\u003e\n\u003cp\u003eThe module installs into a single slot of any standard 1771 Universal I\/O chassis, interacting directly with the system backplane. Its physical weight of 1.35 lbs (0.61 kg) reflects standard rugged industrial packaging, ensuring robust housing and long-term durability in stationary control cabinets and distributed I\/O racks.\u003c\/p\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e1771-OQC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eAllen-Bradley\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Line\u003c\/td\u003e\n\u003ctd\u003ePLC-5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule Type\u003c\/td\u003e\n\u003ctd\u003eIsolated DC Output Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Outputs\u003c\/td\u003e\n\u003ctd\u003e8 Channels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNominal Voltage\u003c\/td\u003e\n\u003ctd\u003e24 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIsolation Type\u003c\/td\u003e\n\u003ctd\u003eIndividual Channel Isolation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSlot Requirement\u003c\/td\u003e\n\u003ctd\u003e1 Slot\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e1.35 lbs (0.61 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003cp\u003eFrequently Asked Questions\u003c\/p\u003e\n\u003cp\u003eQ: What function does optical isolation serve on the 1771-OQC module outputs?
