It features four individually isolated, selectable contact outputs capable of switching heavy-duty AC inductive loads up to 250 VAC or DC loads up to 175 VDC. This module provides robust electrical isolation between controller logic and high-power industrial actuators.\u003c\/p\u003e\n\u003ch3\u003ePower Switching and Contact Isolation\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003e1771-OX\u003c\/strong\u003e provides four isolated output channels that accommodate flexible voltage configurations across field circuits. Each contact can independently switch AC voltages up to 250 VAC for inductive loads or DC voltages up to 175 VDC. The electromechanical relay design prevents ground loops and protects the PLC backplane from high-energy field transients.\u003c\/p\u003e\n\u003ch3\u003eChassis Installation and Field Wiring\u003c\/h3\u003e\n\u003cp\u003eThe module installs into any standard slot within a 1771 I\/O chassis backplane. Field connections are wired directly to a compatible removable terminal block attached to the chassis, allowing maintenance personnel to replace the module body without rewiring field devices. Physical keying ensures proper module positioning.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\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-OX\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 Type\u003c\/td\u003e\n\u003ctd\u003ePower Contact Output Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eArchitecture\u003c\/td\u003e\n\u003ctd\u003ePLC-5 1771 Universal I\/O\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Outputs\u003c\/td\u003e\n\u003ctd\u003e4 Selectable Isolated Outputs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum AC Voltage\u003c\/td\u003e\n\u003ctd\u003e0–250 VAC (Inductive Loads)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum DC Voltage\u003c\/td\u003e\n\u003ctd\u003e0–175 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule Weight\u003c\/td\u003e\n\u003ctd\u003e2.29 lbs (1.04 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What are the maximum voltage switching ratings for the 1771-OX module?
