FAQs
This relay mounts on TH35-7.5 DIN rails and uses screw terminals suitable for flexible 2.5 mm² or rigid conductors. It supports IP20 terminal protection and operates across -40 to +70 C, providing a robust solution for standard industrial cabinets and modular panels. Design-in remains straightforward with widely adopted mounting standards.
The 24 V AC/DC control input is compatible with most PLC and logic modules used in automation. The SPDT output switches up to 6 A at 250 VAC, enabling direct interfacing to coils, indicators, and low-power field devices without additional interfaces, reducing wiring complexity and potential fault pathways.
Yes. The device provides reliable, isolated control signals with fast response and low contact resistance due to gold-plated contacts. Its DIN rail mounting and secure screw-terminals speed installation in packaging lines, while its temperature tolerance supports varying line conditions typical of packaging and conveying equipment.
The relay carries CE, UKCA, UL 508, CSA, and cURus certifications, among others. These approvals support regulatory compliance across Europe, the UK, and North America, simplifying supplier qualification, reducing validation time, and enabling global deployments without per-market redesigns.
Gold-plated contacts reduce wear and arcing, extending service life and lowering maintenance intervals. DIN-rail mounting and secure wiring decrease commissioning time, while robust specifications (-40 to +70 C, IP20) minimize downtime in harsh environments, delivering a favorable total cost of ownership for mid- to high-volume automation projects.
