Automation Direct C0-16NE3 Programmable Controller

The Automation Direct C0-16NE3 is a 16-point discrete input module for AutomationDirect's CLICK PLC family that accepts sink or source AC/DC signals on a 24 VAC/VDC supply, making it ideal for wiring 24‑V sensors, pushbuttons, and limit switches in compact control panels. It draws power from the CLICK bus (24 VDC, up to 40 mA when all inputs are on) and provides four isolated commons to organize inputs. Each of the 16 inputs has an impedance of 6.8 kΩ at 24 VAC/VDC, with a typical input current of 3.4 mA (maximum 5 mA). The ON voltage threshold is greater than 18 V and the OFF threshold is below 4 V, with response times ranging from 5 to 40 ms to support reliable, real‑time sensing. The module supports ZIPLink pre-wired PLC connections for straightforward wiring to the CPU and includes a removable terminal block (AutomationDirect p/n C0-16TB). It weighs about 3.2 oz (90 g), making it suitable for compact panels. This module is commonly used for interfacing 24‑V sensors, pushbuttons, and switches in machine control, panel automation, and safety interlock circuits, delivering a compact, bus-powered 16‑input solution for discrete input needs.
