Connect field wiring using the 1771-WA wiring arm, which allows module replacement without disconnecting wiring. The module supports ½, 1, and 2-slot I\/O addressing configurations. Ensure input devices are compatible with the 120V AC\/DC rating and observe the specified signal delay times for AC (24 ms) and DC (10 ms ON, 20 ms OFF) operation.\u003c\/p\u003e\n\n\u003ch3\u003eFAQs\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong style=\"color: #1a5f7a;\"\u003eQ1:\u003c\/strong\u003e How many inputs does the 1771-IA2 provide?\u003c\/p\u003e\n\u003cp\u003e\u003cstrong style=\"color: #1a5f7a;\"\u003eA1:\u003c\/strong\u003e 8 digital input channels rated at 120V AC\/DC.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong style=\"color: #1a5f7a;\"\u003eQ2:\u003c\/strong\u003e What is the difference between AC and DC signal delay?\u003c\/p\u003e\n\u003cp\u003e\u003cstrong style=\"color: #1a5f7a;\"\u003eA2:\u003c\/strong\u003e AC signal delay is 24 ms (±10) for both ON and OFF states.
