Product Description

​The Omron H3CR-F8N is a solid-state timer designed for precise time-delay operations in industrial applications. Encased in a compact 48 x 48 mm DIN standard housing, it offers a time range from 0.05 seconds to 300 hours, making it versatile for various timing requirements. The timer features a flicker ON start operation mode and provides a dual-pole double-throw (DPDT) relay output capable of switching up to 5 A at 250 VAC or 30 VDC, suitable for controlling multiple circuits simultaneously. It operates with a supply voltage of 24 to 48 VAC at 50/60 Hz or 12 to 48 VDC, with a ripple of 20% maximum, ensuring compatibility with diverse power systems.
