DR2224D20U

## **DR22 SERIES | AC OUTPUT LOW-PROFILE** DIN RAIL MOUNT SOLID STATE RELAYS 

Nova22 DR22 Series are last generation DIN Rail mount Solid State Relays in a 22.5mm wide industrial package. “Low-profile” versions come with an integral low-profile heat sink and a TRIAC output rated for up to 30 Amps at 280 VAC. This provides users with a cost-effective solution to switch small and medium AC loads that allows to reduce manufacturing cost and cabinet space without sacrificing performance, and to optimize equipment operation time. 

These powerful and ready to use SSRs are perfect for applications where the depth of the control panel is limited, and they are UL approved and CE compliant.
