Bi-power Relays

Power-switching Compact

General-purpose Relays

• 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.

• Single-pole and double-pole models have AC4

ratings and DC2 ratings (operating coil ratings: 100/

110 VAC, 110/120 VAC, 200/220 VAC, 220/240 VAC,

and 100/110 VDC).

• Three-pole and four-pole models have AC4 ratings

and DC2 ratings (operating coil ratings: 100/110

VAC, 200/220 VAC and 100/110 VDC).

Refer to the Common Relay Precautions.

Refer to the standards certifications and compliance section of your

OMRON website for the latest information on certified models.

Model Number Structure

Note: 1. Cells with a diagonal line cannot be manufactured. Ask your OMRON representative for details on manufacturing products for cells

containing “---” in the above table.

2. If #187 tab terminals are required, use the LY1F-T2 or LY2F-T2 (single-pole or double-pole models only).

3. Refer to page 12 for information on plug-in terminal and socket combinations.

4. Items with an asterisk (*) in the table are certified for UL, CSA, and SEV. This is indicated with a certification mark on the products.

5. Items with two asterisks (**) in the table are certified for UL and CSA. This is indicated with a certification mark on the products.

6. All models in the table are certified for IEC (TÜV).

7. The models with plug-in terminals (single-pole, double-pole, and 4-pole) were combined with the PTF-E for the EC Declaration of

Conformity. These products display the CE Marking.
