IDEC RU4S-A24 Power Relay - 24VAC Coil, 4PDT, 6A Contacts, Plug-in, RU Series
High-performance 4PDT (4-pole double throw) general-purpose power relay from the robust RU Series, designed for versatile applications in industrial control systems. This specific model features a 24VAC coil, making it suitable for standard AC control circuits. With its 4PDT contact configuration, it can switch up to four independent circuits, offering excellent flexibility for complex control tasks. The contacts are rated for 6A at 120/240VAC and 30VDC, ensuring reliable switching of various loads. Built with a focus on durability and environmental responsibility, the relay incorporates cadmium-free silver tin oxide indium (AgSnOIn) contacts and a unique solder-free (spot welded) construction, eliminating internal wires for enhanced reliability and lead-free compliance.
Key operational features of the RU4S-A24 include a standard non-polarized LED indicator for clear status visualization and a mechanical flag indicator for visual confirmation of contact status. It also includes a manual latching lever with color-coding, and a snap-on marking plate for easy identification. The relay exhibits fast operation and release times (20 ms max) and a long mechanical life of 20 million operations (AC), ensuring extended service life. It is designed to operate within a wide temperature range of -55°C to +70°C and provides IP40 degree of protection. High dielectric strength (2,500VAC between contact and coil/poles) and resistance to shock (15G operating) and vibration (1.0 mm p-p amplitude) further enhance its robustness. The 24VAC coil consumes 1.1-1.4VA, with a coil resistance of 164 Ω. The relay is UL Recognized and CSA Certified, confirming its adherence to stringent safety and performance standards.
This IDEC RU4S-A24 relay is an ideal choice for applications requiring reliable multi-circuit switching, motor control, or signal interfacing in diverse industrial and commercial environments, leveraging its robust design and comprehensive feature set for dependable operation.
