AutomationDirect D3-08NA-1 8-Point 110VAC Input Module

AutomationDirect D3-08NA-1 is a DirectLogic DL305 eight-point input module designed for 110 VAC sensing. It provides eight discrete inputs across two isolated commons (four inputs per common) with a non-removable terminal block for rugged field wiring, and it accepts an input voltage range of 85–132 VAC at 47–63 Hz. The module activates when the input exceeds 80 VAC and deactivates below 20 VAC, drawing about 15 mA at 50 Hz (18 mA at 60 Hz) with a 10 kΩ input impedance, using optical isolation from the DL305 logic; the reference circuit shows a 2.2 kΩ resistor and 0.33 μF capacitor in the input path. Weighing roughly 5 oz (140 g), it includes field-side status indicators and is intended for use with DirectLogic DL305 controllers. UL listed (File E157382) and documented in AutomationDirect manuals, D3-08NA-1 is listed as retired as of April 8, 2022, and is commonly referenced as an 8-point 110/120 VAC input module for DL305 systems.
