Omron K8AK-VW3 24VAC/DC Voltage Monitoring Relay – 1-Phase, 20–600VAC/DC, 2 x SPDT

The Omron K8AK-VW3 is a high-performance voltage monitoring relay designed for single-phase systems requiring precise supervision of overvoltage and undervoltage conditions. Operating on a 24VAC/DC power supply, it provides reliable protection for equipment across a wide monitoring range of 20 to 600 VAC/DC, making it ideal for process control, electrical panels, and automation systems.

Compact and durable, the 22.5 mm-wide DIN rail mount design includes two SPDT relay outputs, a configurable 0.1–30 second time delay, and bright LED status indicators for intuitive operation. Inputs are isolated from the power supply, ensuring safe, stable performance in industrial environments.
