Automation Direct D2-16ND3-2 Input Module

The D2-16ND3-2 is a 16-point DC input module for AutomationDirect’s DirectLogic DL205 PLCs, designed to accept sinking or sourcing 20–28 VDC signals (nominal 24 VDC) with two isolated commons and eight inputs per common. Peak input voltage is 30 VDC (10 mA), with ON voltage at least 19 VDC and OFF at 7 VDC max; input impedance is 3.9 kΩ and typical input current is 6 mA at 24 VDC. The module provides 16 discrete inputs across two isolated commons and ships with a removable terminal block (D2-16IOCON) and a logic-side status indicator for quick diagnostics. Base power requirement is 100 mA at 5 VDC. Transition times are 3–9 ms for both OFF-to-ON and ON-to-OFF events. Weight is approximately 2.3 oz (65 g). As part of the DL205 I/O family, it integrates with DirectSOFT programming software (version 4.0 or later) and is used to expand the digital input capability of the DL205 system. The PN for this model is D2-16ND3-2, and it is documented as a 16-point DC input module with two isolated commons and eight inputs per common.
