IDEC Relays RU4S-C-A110 Relay
For contractors and facilities engineers requiring high-density switching in a midget footprint, the IDEC RU4S-C-A110 Universal Plug-in Relay offers an industrial-grade solution for complex control circuits. This 4PDT relay is engineered with a unique solder-free internal construction, utilizing spot welding to eliminate potential weak lead-free solder points, thereby increasing structural integrity during high-vibration operation. Rated for 6 Amps at 110-120VAC, the RU Series provides reliable switching across four poles, making it ideal for interlocking HVAC controls, sequencing industrial machinery, or managing multi-stage instrumentation loads. Technical diagnostics are streamlined via the integrated non-polarized LED indicator and a visible mechanical flag, allowing for immediate status confirmation without the need for additional test equipment. The orange color-coded manual latching lever further simplifies circuit testing by allowing technicians to manually actuate the contacts for momentary or locked-down troubleshooting.
Key Benefits- Enhanced Reliability: Solder-free construction and lead-free design minimize internal failure points for long-term performance in demanding HVACR environments.
- Dense Switching Capacity: Features a 4PDT contact configuration capable of handling 6A loads, providing high-pole-count switching in a compact 14-pin plug-in form factor.
- Visual Diagnostics: Equipped with both a high-brightness LED and a mechanical flag indicator to verify coil energization and contact position at a glance.
- User-Centric Testing: Manual latching lever allows for quick circuit verification; color-coded orange to signify 110-120V AC coil type.
- Industrial Compliance: Meets global standards including UL, CSA, and EN, ensuring compatibility with standard 14-pin relay sockets (such as the SY4S-05).
What is the maximum current rating if all poles are used simultaneously?
For the RU4 series, the maximum allowable total current through neighboring poles is 6A. At rated load, ensure the sum of the current across aligned poles does not exceed this limit to prevent thermal buildup.
Can this relay be mounted directly to a PCB?
The RU4S-C-A110 is a blade-style plug-in relay designed for socket mounting. For direct PCB integration, the RU4V series would be the appropriate technical cross-reference.
How do I distinguish between AC and DC coil versions in the field?
IDEC utilizes color-coded latching levers for the RU Series. Orange/Red levers indicate an AC coil (like this 110-120V model), while Green/Blue levers signify a DC coil.
