Automation Direct D2-16ND3-2 Proximity Sensor

D2-16ND3-2 is a 16-point, 24V DC discrete input module for AutomationDirect DirectLogic DL205 PLC systems. It provides two isolated commons (8 input points per common) and supports either sinking or sourcing wiring to a common, making it suitable for connecting a variety of 24V sensors, including proximity switches, to the PLC inputs. Each input accepts 20–28 VDC, with a peak rating up to 30 VDC (10 mA), and a minimum ON voltage of 19 VDC with OFF at 7 VDC maximum. The input impedance is about 3.9 kΩ, drawing roughly 6 mA per channel at 24V. Minimum ON current is 3.5 mA and maximum OFF current is 1.5 mA. State changes respond in about 3–9 ms. The module weighs approximately 2.3 oz (65 g) and uses a removable terminal block for straightforward installation. It is designed as part of AutomationDirect’s DirectLogic DL205 family and is commonly used to convert 24V sensor signals into PLC inputs in industrial control schemes. This part is identified as D2-16ND3-2, offering 16 inputs, 24V DC operation, sinking/sourcing compatibility, and easy wiring through removable terminals for quick field wiring and maintenance.
