Overview
The 1790D-OV16 is a high-density CompactBlock LDX I/O base module designed for DeviceNet networks, providing 16 non-isolated sinking outputs in a space-saving footprint. Engineered for rapid integration via its 37-pin D-shell connector, the 1790D-OV16 handles up to 4.0A per common, ensuring stable switching for high-duty solenoid valves and industrial relays.
Oiltech Controls’s Insight & Application
- Engineering Verdict: The 1790D-OV16 is the “workhorse” for DeviceNet-based localized control. Its sinking logic is ideal for NPN-compatible loads.
- Internal Architecture: Note that Com 0/Com 2 are internally bridged; professional installers must ensure polarity consistency to prevent common-mode noise across the D-shell interface.
- Optimal Device Fit: Specifically tailored for compact control cabinets, robotic end-effectors, and distributed conveyor systems using Allen-Bradley DeviceNet scanners.
