DA149 Intrinsically Safe Relays

Product catalog summary

Overview: The DA-149 Series comprises intrinsically safe relays designed for signal transfer between safe and hazardous areas. These relays facilitate communication between equipment in different zones without requiring system certification due to their classification as 'simple apparatus'.

Specifications: The relays are available in four models: DAA149, DAB149, DAD149, and DAE149. They are characterized by low power consumption, galvanic isolation, and suitability for DIN-rail mounting. The relays operate with minimal power, requiring less than 60µA at 4V, making them compatible with loop-powered systems.

Electrical Safety: The relays are non-energy storing devices, ensuring safety in hazardous areas. They comply with EMC standards EN61000-6-2:2001 for immunity and EN61000-6-4:2001 for emissions.

Relay Models:

DAA149: Transfers signals from hazardous to safe areas, safe-area mounting.
DAB149: Suitable for hazardous area mounting, operates up to 40°C.
DAD149: Also for hazardous area mounting, operates up to 70°C.
DAE149: Transfers signals from safe to hazardous areas, safe-area mounting.

Approvals: All models are approved by BASEEFA to CENELEC standards, ensuring compliance with safety regulations for use in hazardous environments.

Construction and Mounting: The relays are housed in resin-filled polyamide casings and can be mounted on DIN rails conforming to EN50035 standards.

Ordering Information: Each model is specified for different operational zones and temperature ranges, with varying fuse ratings to suit specific applications.
