AutomationDirect C0-16ND3 Discrete Input Module

The AutomationDirect C0-16ND3 is a 16-point, 24 VDC discrete input module for the CLICK PLC system that supports both sinking and sourcing inputs, enabling flexible wiring from sensors and switches. It provides four isolated commons (4 points per common) and ships with a removable terminal block for quick field wiring (C0-16TB). Electrical specs include a 21.6–26.4 VDC input range, typical 4.0 mA per channel, maximum 5.0 mA, and an input impedance of 6.8 kΩ; ON voltage is greater than 19 VDC and OFF voltage is less than 7 VDC, with ON-to-OFF and OFF-to-ON response times up to 10 ms (typical 3 ms and 2 ms, respectively). The module draws bus power from the 24 VDC supply and supports up to 40 mA when all inputs are on, weighs about 3.2 oz (90 g), and is designed to be stacked with other CLICK I/O modules on a CLICK CPU to expand system I/O—up to eight modules in a single CPU configuration.
