Automation Direct D2-08ND3 Digital Input Module

The Automation Direct D2-08ND3 is an 8-point discrete input module for the DirectLogic DL205 family, designed to accept 12–24 VDC signals from sensors and switches. Each module provides eight independent digital inputs with a single common per module (two I/O terminal points) and a removable D2-8IO terminal block, supporting both sinking and sourcing configurations. Electrical specifications include a 10.2–26.4 VDC input voltage range (peak 26.4 VDC), ON voltage minimum 9.5 V, OFF voltage maximum 3.5 V, input impedance 2.7 kΩ, and input current of about 4.0 mA at 12 V and 8.5 mA at 24 V, with response times from 1 to 8 ms. At approximately 2.3 oz (65 g), the D2-08ND3 fits into the DL205 I/O rack and provides a straightforward way to read digital signals from field devices such as sensors and switches.
