The AutomationDirect D3-08ND2 is an 8-point, 24 VDC current-sourcing input module for the DL305 DirectLogic PLC family, designed as a drop-in replacement part. It provides two internally connected common terminals, four inputs per common, and ships with a non-removable terminal block for field wiring; each input draws up to 12 mA when ON and presents roughly 1.8 kΩ input impedance, with a maximum OFF current of about 3 mA. The module operates on a 18–36 VDC input range, weighs approximately 4.2 oz (120 g), and is commonly used to connect sensors and switches to a DL305 PLC for straightforward digital input monitoring and control.
