Feature to benefit: 24 V AC/DC control voltage enables universal compatibility with PLCs and safety circuits, reducing inventory needs and wiring errors in control cabinets. Business impact: Faster commissioning, lower part counts, and reduced downtime during upgrades. Application: Suitable for automation panels in machine manufacturing and packaging lines. Feature to benefit: SPDT (1 c/o) output provides flexible control logic with a single relay, enabling normally open or normally closed configurations without additional parts. Application: Used for signal gating, mechanical interlocks, and logic inversion in control circuits. Feature to benefit: Gold-plated contacts minimize contact wear and corrosion, delivering stable performance over millions of switching cycles. Application: Critical in DC control paths and high-reliability cabinets. Feature to benefit: Spring terminals and 2.5 mm² wiring capacity simplify field wiring, provide solid vibration resistance, and speed up installation. Application: Ideal for compact DIN rail assemblies in harsh environments. Feature to benefit: DIN rail mounting TH35-7.5 and compact footprint save panel space and simplify retrofits. Application: Widely used in retrofit projects and new builds with standard mounting rails. Feature to benefit: Broad compliance with UL 508, CE, UKCA, CSA and RoHS supports global deployment and regulatory adherence. Application: Suitable for multinational facilities and certified process environments. Feature to benefit: Wide operating temperature range -40 to +70 °C ensures reliability in industrial or outdoor control enclosures. Application: Used in harsh manufacturing zones, process plants, and outdoor panels that require rugged relays.

FAQs
Yes. The unit mounts on TH35-7.5 DIN rails per IEC 60715 and uses spring terminals capable of 2.5 mm² wires. UL/CSA wiring also supports flexible 14 AWG or rigid 14 AWG in accordance with applicable standards, making field wiring straightforward and reliable in typical control cabinets.
The relay offers 24 V AC/DC control, SPDT output (1 c/o), and a rated load of 6 A at up to 250 VAC. It supports AC-12 operation at 230 V and DC-12 at 24 V with 6 A, while DC-13 is rated at 1 A at 24 V. These ratings suit common automation control tasks with solid safety margins.
Yes, but with limits. The DC-13 rating is 1 A at 24 V, so it’s suitable for switching DC-auxiliary circuits or small loads. For higher DC-13 loads, consider devices with higher ratings or multiple relays in parallel, ensuring the total load remains within the specified 1 A limit.
The CR-S family including this model carries UL 508, CSA certification, and cURus, along with CE and UKCA declarations. It is RoHS compliant, offering regulatory assurance for multinational deployments and reducing compliance risk in global supply chains.
The gold-plated contacts, IP20 protection, and robust DIN-rail mounting reduce contact wear and wiring faults, lowering maintenance costs and downtime. Quick field wiring, reliable switching, and wide temperature tolerance (-40 to +70 °C) translate to higher equipment uptime and longer service intervals in harsh industrial environments.
