Connect field devices to the 8 inputs using the 1771-WA wiring arm. Verify AC input voltage stays within 12-28 V for reliable on state operation. Keep off state current below 2.8 mA to prevent false triggering. Use the configuration plug to select fault mode behavior for output failure.\u003c\/p\u003e\n\n\u003ch2\u003eEngineering Advantages\u003c\/h2\u003e\n\u003cp\u003eSingle slot design saves chassis space in PLC 5 systems. Lightweight 450 g construction reduces rack strain. Electrical optical isolation protects the processor from field transients.
