It provides a quick-disconnect wiring interface for up to 8-point digital AC and DC I\/O modules, enabling maintenance personnel to swap modules without removing individual field conductors. Operating across a wide 24 to 220 V AC\/DC voltage spectrum, the \u003cstrong\u003e1771-WA\u003c\/strong\u003e ensures secure wiring connections and reduces equipment downtime during system servicing.\u003c\/p\u003e\n\u003ch3\u003eModular Swing Arm Mechanism\u003c\/h3\u003e\n\u003cp\u003eThe 1771-WA connects directly to the pivot bar at the bottom of a 1771 I\/O chassis slot. It swings upward to latch onto the front of the installed module, mating field wiring directly with the module's terminal pins. When replacing or inspecting hardware, technicians release the locking tab and swing the arm away from the module. This design retains the complete field cable harness, eliminating re-wiring errors and preserving loop integrity.\u003c\/p\u003e\n\u003ch3\u003eTerminal Layout \u0026amp; Electrical Parameters\u003c\/h3\u003e\n\u003cp\u003eThe unit features 10 screw-clamp terminals: terminals 0 through 7 serve as 8 individual I\/O signal connection points, terminal A accommodates power high (L1\/+DC), and terminal B handles return low (L2\/Common Return). The terminal contact plating consists of 9 tin-plated contacts and 1 gold-plated contact to ensure high-conductivity signal transfer across a 24 to 220 V AC\/DC voltage range. Recommended screw terminal tightening torque is 7–9 in-lb (0.8–1.0 N·m).\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-WA\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\u003eField Wiring Swing Arm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem Compatibility\u003c\/td\u003e\n\u003ctd\u003e1771 I\/O Chassis Platform\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Terminals\u003c\/td\u003e\n\u003ctd\u003e10 (Terminals 0-7, A, B)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupported I\/O Points\u003c\/td\u003e\n\u003ctd\u003e8 Points\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVoltage Rating\u003c\/td\u003e\n\u003ctd\u003e24 - 220 V AC\/DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eContact Plating\u003c\/td\u003e\n\u003ctd\u003e9 Tin-Plated \/ 1 Gold-Plated\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTerminal Screw Torque\u003c\/td\u003e\n\u003ctd\u003e7 - 9 in-lb (0.8 - 1.0 N·m)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.07 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: Which Allen-Bradley modules use the 1771-WA field wiring arm? A: The 1771-WA is used with general-purpose 8-point 1771 digital I\/O modules operating on AC or DC control voltages, such as the 1771-IA, 1771-IB, 1771-OA, and 1771-OB.\u003c\/p\u003e\n\u003cp\u003eQ: What is the purpose of terminals A and B on the 1771-WA arm?
