RU Relays & Sockets RU Series Universal Relays Key features: Full featured universal miniature relays Designed with environment taken into consideration Two terminal styles: plug-in and PCB mount Non-polarized LED indicator No internal wires, lead-free construction Cadmium-free contacts Mechanical flag indicator Manual latching lever with color coding for AC or DC coil Snap-on yellow marking plate optional marking plates are available in four other colors Maximum contact ratings: 10A (RU2), 6A (RU4), 3A (RU42) UL Recognized, CSA Certified, EN Compliant EN61810-1 With Latching or Momentary Lever Latching and Momentary Lever Using the lever, operation can be checked without energizing the coil. Mechanical Indicator* The lever is color coded for AC and DC coils. The contact position can be confirmed through Latching Momentary the five small windows. AC coil: Orange Red Marking Plate DC coil: Green Blue Standard yellow marking plate is easily replaced with optional marking plates in four colors for In Normal Operation easy identification of relays. LED Indicator* Non-polarized green LED indicator is standard provision for plug-in terminal, latching lever types Note: Turn off the power to the relay coil when using the latching lever. After checking the operation, return the latching lever in the normal position. Standard (without lever) AC/DC Color Marking For identification of AC or DC coils. AC coil: Yellow DC coil: Blue Coil Voltage Tape Color Mechanical Indicator* 24V AC White Marking Plate 100 to 110V AC Clear 110 to 120V AC Blue LED Indicator* Non-polarized green LED indicator is standard 200 to 220V AC Black provision for plug-in terminal types. 220 to 240V AC Red 24V DC Green 6V DC AC Coil DC Coil 12V DC Voltage marking on yellow tape 48V DC *Not available on PCB type. 110V DC 1705151135 www.IDEC.com 890 Circuit Breakers Terminal Blocks Contactors Timers Relays & Sockets Signaling Lights Switches & Pilot LightsSwitches & Pilot Lights Signaling Lights Relays & Sockets Timers Contactors Terminal Blocks Circuit Breakers RU Relays & Sockets Part Number Selection Part Number Coil Voltage Code Contact Model Standard With Latching Lever With Momentary Lever (Standard Stock in bold) A24, A110, A220 DPDT (10A) Standard RU2S-C-0 RU2S-0 RU2S-M-0 D6, D12, D24, D48, D110 With RC (AC coil only) RU2S-CR-0 RU2S-R-0 RU2S-MR-0 A110, A220 With diode (DC coil only) D6, D12, D24, D48, D110 RU2S-CD-0 RU2S-D-0 RU2S-MD-0 A24, A110, A220 PCB RU2V-NF-0 D6, D12, D24, D48, D110 A24, A110, A220 4PDT (6A) Standard RU4S-C-0 RU4S-0 RU4S-M-0 D6, D12, D24, D48, D110 With RC (AC coil only) A110, A220 RU4S-CR-0 RU4S-R-0 RU4S-MR-0 With diode (DC coil only) D6, D12, D24, D48, D110 RU4S-CD-0 RU4S-D-0 RU4S-MD-0 A24, A110, A220 PCB RU4V-NF-0 D6, D12, D24, D48, D110 A24, A110, A220 4PDT Bifurcated (3A) Standard RU42S-C-0 RU42S-0 RU42S-M-0 D6, D12, D24, D48, D110 With RC (AC coil only) RU42S-CR-0 RU42S-R-0 RU42S-MR-0 A110, A220 With diode (DC coil only) RU42S-CD-0 RU42S-D-0 RU42S-MD-0 D6, D12, D24, D48, D110 A24, A110, A220 PCB RU42V-NF-0 D6, D12, D24, D48, D110 1. Plug-in terminal models have an LED indicator and a mechanical indicator as standard. Ordering Information 2. PCB models do not have an LED indicator or a mechanical indicator.
