keyence KV-16DR programmable controller

Overview

KV-16DR is an all-in-one miniature programmable logic controller from Keyence’s renowned KV automation series, engineered for low-speed, small-scale discrete automation tasks. This integrated 16-point I/O PLC combines digital input circuits and mechanical relay outputs inside a slim DIN rail-mount housing, eliminating the need for separate expansion modules for basic on-off sequence control.

The KV-16DR features a fixed layout of 8 digital inputs + 8 mechanical relay outputs. Its relay terminals directly drive solenoid valves, indicator lamps, miniature contactors and low-power actuators without external intermediate relay boards. Equipped with built-in RS232 and RS485 communication ports, it supports multiple industry-standard protocols to exchange real-time data with HMIs, inverters, barcode readers and upper monitoring systems seamlessly. The unit adopts Keyence proprietary anti-interference circuit layout to suppress electromagnetic noise from workshop motors and servo drives, ensuring glitch-free logic operation during nonstop 24/7 cabinet operation. Its ultra-compact lightweight body drastically reduces cabinet space occupation, making KV-16DR a cost-effective core control component for new small automated machine assembly and aging Keyence KV-series PLC replacement renovation projects.
