H3DK-M2 – 24–240V AC/DC Multi-Range Analog Timer Relay
Description
The H3DK-M2 is a multi-range analog timer relay designed for precise control in industrial automation, process timing, and sequential operations. Supporting both AC and DC input voltages (24–240V), this Omron relay provides adjustable time ranges, dual-mode operation, and a compact DIN-rail mount design for easy panel integration. It’s ideal for controlling motor starts, lighting systems, conveyors, and PLC-based timing logic.
