**Bi-power Relays LY** CSM_LY_OEE_DS_E_ 2 _ 5 ## **Power-switching Compact General-purpose Relays** - Wiring work can be shortened by as much as 60%* compared to conventional screw terminal sockets by combining with push-in plus terminal sockets (PYF- @ - PU) that feature light insertion force and strong pullout strength to achieve less wiring work. - The standard models include models that are compliant with the UL, CSA, and SEV safety standards and with the Electrical Appliances and Material Safety Act. - Equipped with an arc barrier for arc interruption. - Withstand voltages up to 2,000 V. - New built-in diode and built-in CR circuit models have joined the series. - The lineup also includes models that are compliant with the LR and VDE safety standards. Refer to the standards certifications and compliance section of your OMRON website for the latest information on certified models. - When both push-in plus terminals and screw terminal sockets are combined with plug-in terminal types (according to actual OMRON measurements as of November 2015) **Refer to the** _**Common Relay Precautions**_ **.** ## **Model Number Structure** |**Structure**<br>**Classification**<br>**Number**<br>**of poles**<br>~~Pf~~|**Structure**<br>**Classification**<br>**Number**<br>**of poles**<br>~~Pf~~|**Structure**<br>**Classification**<br>**Number**<br>**of poles**<br>~~Pf~~|**Relays with Plug-in Terminals**<br>**With operation indicators**<br>~~Pf~~|**Relays with Plug-in Terminals**<br>**With operation indicators**<br>~~Pf~~|**Relays with PCB Terminals**<br>~~ais~~|**Case-surface mounting**<br>~~ais~~| |---|---|---|---|---|---|---| |||||**With operation indicators**<br>~~Pf~~||| |**Standard models**<br>**Compliance with**<br>**Electrical Appliances**<br>**and Material Safety Act**<br>~~Pf~~|**1**<br>~~Pf~~<br>~~a~~||***LY1**<br>~~Pf~~<br>|LY1N**<br>~~Pf~~<br>|***LY1-0**<br>~~ais~~|***LY1F**<br>~~ais~~| ||**2**<br>**Bifur-**<br>**cated**<br>~~ee~~||***LY2**<br>~~ee~~|LY2N**<br>~~ee~~|***LY2-0**|***LY2F**| |||**Bifur-**<br>**cated**<br>~~ee~~|LY2Z**<br>~~ee~~|LY2ZN**<br>~~ee~~|LY2Z-0**|LY2ZF**| ||**3**<br>~~ee~~<br>~~a~~||---<br>~~ee~~<br>~~a~~|---<br>~~ee~~<br>~~a~~|***LY3-0**<br>~~a~~|---<br>~~a~~| ||**4**<br>~~a~~||***LY4**<br>~~a~~|LY4N**<br>~~a~~|***LY4-0**<br>~~a~~|***LY4F**<br>~~a~~| |**Models with diode for**<br>**coil surge absorption**<br>**(DC coil specification**<br>**only)**<br>~~a~~<br>ge|**1**<br>~~a~~<br>~~>~~||LY1-D**<br>~~a~~<br>~~pT~~|LY1N-D2**<br>~~a~~<br>~~pT.~~|---<br>~~a~~|---<br>~~a~~| ||**2**<br>**Bifur-**<br>**cated**<br>~~a~~<br>~~>~~<br>~~ee~~||LY2-D**<br>~~a~~<br>~~pT~~|LY2N-D2**<br>~~a~~<br>~~pT.~~|---<br>~~a~~|---<br>~~a~~| |||**Bifur-**<br>**cated**<br>~~a~~<br>~~>~~<br>~~ee~~|LY2Z-D**<br>~~a~~<br>~~pT~~<br>~~a~~|LY2ZN-D2**<br>~~a~~<br>~~pT.~~|---<br>~~a~~|---<br>~~a~~| ||**4**<br>~~a~~<br>~~>~~<br>~~ee~~<br>~~ee~~||LY4-D**<br>~~a~~<br>~~pT~~<br>~~a~~<br>~~ee~~|LY4N-D2**<br>~~a~~<br>~~pT .~~<br>~~ee~~|---<br>~~a~~|---<br>~~a~~| |**Models with CR circuits**<br>**for coil surge**<br>**absorption**<br>**(AC coil specification**<br>**only)**<br>~~ee~~|**1**<br>~~ee ~~<br>~~ee~~||**---**<br> ~~a~~<br>~~ee~~|**---**<br>~~ee~~||| ||**2**<br>**Bifur-**<br>**cated**<br>~~ee~~||LY2-CR**<br>~~ee~~<br>~~a~~|LY2N-CR**<br>~~ee~~||| |||**Bifur-**<br>**cated**|LY2Z-CR**<br>~~a~~|LY2ZN-CR**||| - **Note: 1.** Cells with a diagonal line cannot be manufactured.

(Normal tightening torque: 0.98 N·m) - For Relays with Tab Terminals, select a wire diameter for the lead wires that connect to the faston receptacle terminals that is within the allowed range for the load current. - Do not impose excessive external force on the Relay when inserting the Relay to the faston receptacle or pulling the Relay out from the faston receptacle. Do not attempt to insert a terminal diagonally or insert or pull out more than one terminal at the same time. - LY Single-contact Relays are for power switching applications. Do not use the LY Series for switching minute loads of 100 mA or less, such as signals. ## **About the Built-in Diode and CR Elements** The diode or CR element that are built into the Relay are designed to absorb the reverse voltage from the Relay coil. If a large surge in voltage is applied to the diode or CR element from an external source, the element will be destroyed. If there is the possibility of large voltage surges that could be applied to the elements from an external source, take any necessary surge absorption measures. ## **Applying 10 A or More When Using an LY1 with the Following Sockets** When you use an LY1 in combination with the PTF-08-PU, PTF-08PU-L, PTF08A, PTF08A-E, or PT08, connect each of the following terminal pairs: (1) to (2), (3) to (4), and (5) to (6). ## **Relay Replacement** To replace the Relay, turn OFF the power supply to the load and Relay coil sides to prevent unintended operation and possible electrical shock. ## **Attaching and Removing Relay Hold-down Clips** When you attach a Hold-down Clip to or remove it from a Socket, wear gloves or take other measures to prevent injuring your fingers on the Hold-down Clip. **21** ## **OMRON AUTOMATION AMERICAS HEADQUARTERS •** Chicago, IL USA **•** 847.843.7900 **•** 800.556.6766 **•** automation.omron.com ## **OMRON CANADA, INC. • HEAD OFFICE** Toronto, ON, Canada • 416.286.6465 • 866.986.6766 • automation.omron.com **OMRON ELECTRONICS DE MEXICO • HEAD OFFICE** Ciudad de México • 52.55.5901.4300 • 01.800.386.6766 • mela@omron.com ## **OMRON ELETRÔNICA DO BRASIL LTDA • HEAD OFFICE** São Paulo, SP, Brasil • 55 11 5171-8920 • automation.omron.com ## **OMRON ARGENTINA • SALES OFFICE** Buenos Aires, Argentina • +54.11.4521.8630 • +54.11.4523.8483 mela@omron.com ## **OMRON ELECTRONICS DE MEXICO • SALES OFFICE** San Pedro Garza García, N.L. • 81.12.53.7392 • 01.800.386.6766 • mela@omron.com ## **OTHER OMRON LATIN AMERICA SALES** +54.11.4521.8630 • +54.11.4523.8483 • mela@omron.com ## **OMRON ELECTRONICS DE MEXICO • SALES OFFICE** Eugenio Garza Sada,León, Gto • 01.800.386.6766 • mela@omron.com _Authorized Distributor:_ ## **Controllers & I/O** - Machine Automation Controllers (MAC) • Motion Controllers - Programmable Logic Controllers (PLC) • Temperature Controllers • Remote I/O **Robotics** • Industrial Robots • Mobile Robots ## **Operator Interfaces** - Human Machine Interface (HMI) ## **Motion & Drives** - Machine Automation Controllers (MAC) • Motion Controllers • Servo Systems • Frequency Inverters ## **Vision, Measurement & Identification** - Vision Sensors & Systems • Measurement Sensors • Auto Identification Systems **Sensing** • Photoelectric Sensors • Fiber-Optic Sensors • Proximity Sensors • Rotary Encoders • Ultrasonic Sensors **Safety** - Safety Light Curtains • Safety Laser Scanners • Programmable Safety Systems • Safety Mats and Edges • Safety Door Switches • Emergency Stop Devices • Safety Switches & Operator Controls • Safety Monitoring/Force-guided Relays **Control Components** • Power Supplies • Timers • Counters • Programmable Relays • Digital Panel Meters • Monitoring Products ## **Switches & Relays** - Limit Switches • Pushbutton Switches • Electromechanical Relays • Solid State Relays ## **Software** - Programming & Configuration • Runtime Note: Specifications are subject to change. © 2022 Omron.

About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
