The Automation Direct D4-16ND2 is a high-reliability, 16-point current-sourcing discrete input module designed exclusively for the legacy DirectLOGIC DL405 PLC series. Built by Koyo to deliver precision electrical logic tracking, this module serves as an essential bridge between external industrial hardware—such as field sensors, switches, and proximity devices—and your main processing unit. [1, 2, 3, 4]

Engineered with current-sourcing architectures, it ensures clear logic thresholds with an explicit ON voltage level greater than 9.5 VDC and an OFF voltage level below 4.0 VDC. Internal logic-side status indicators allow diagnostic technicians to visually verify input states instantly on the shop floor. Designed for high operational durability, this component ensures steady signal aggregation inside complex manufacturing and marine machinery setups.

High Density I/O Channeling: Equipped with 16 input channels engineered for scalable machine monitoring and heavy-duty data acquisition.
Industrial Dual Voltage Support: Operates seamlessly across standard 12 to 24 VDC input nominal environments (with a wide 10.2 to 26.4 VDC operating range).
True Electrical Isolation: Features 2 isolated commons (8 points per common) to safeguard your control loop and prevent ground-fault propagation.
Rapid Maintenance Architecture: Features a modular, removable terminal block ensuring minimal downtime during quick hardware swaps.
Robust Heritage & Testing: Genuine PLCDirect / Koyo DirectLOGIC heritage built to withstand rigorous industrial deployments.
