The device connects directly to analog output modules, including the \u003cstrong\u003e1771-OFE\u003c\/strong\u003e series modules (such as \u003cstrong\u003e1771-OFE1\u003c\/strong\u003e, \u003cstrong\u003e1771-OFE2\u003c\/strong\u003e, and \u003cstrong\u003e1771-OFE3\u003c\/strong\u003e), to interface field analog output devices like valve positioners, motor speed controllers, signal converters, or recorders. It pivots on the front of the 1771 I\/O chassis, attaching to the horizontal bar at the bottom, which allows modules to be installed or removed without disconnecting user field wiring.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eEnables module installation and removal without disconnecting field wiring\u003c\/li\u003e\n\u003cli\u003ePivots on the front of the 1771 I\/O chassis for modular maintenance\u003c\/li\u003e\n\u003cli\u003eAttaches to the horizontal bar at the bottom of the 1771 I\/O chassis\u003c\/li\u003e\n\u003cli\u003eIncludes terminal screws for field wiring terminations\u003c\/li\u003e\n\u003cli\u003eIncludes a functional ground connection terminal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eInterfacing 1771 analog output modules with field analog devices\u003c\/li\u003e\n\u003cli\u003eIndustrial process control systems using 1771 I\/O chassis installations\u003c\/li\u003e\n\u003cli\u003eControl panel wiring for valve positioners, motor speed controllers, signal converters, and recorders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\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\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eAllen-Bradley\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCatalog Number\u003c\/td\u003e\n\u003ctd\u003e1771-WC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem Compatibility\u003c\/td\u003e\n\u003ctd\u003e1771 I\/O Chassis\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecommended Cable\u003c\/td\u003e\n\u003ctd\u003eBelden 8761 (Shielded Twisted Pair)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eScrew Torque\u003c\/td\u003e\n\u003ctd\u003e7 to 9 pound-inches (0.6 to 1.1 Nm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Attach the wiring arm to the horizontal bar at the bottom of the 1771 I\/O chassis.
