Ordering Information


Note: 1. When ordering, add the rated voltage to the model number. Rated voltages are given in the coil ratings table in the specifications.Example: MKS2P DC48-------Rated voltage
2. The DC coil comes in two types: standard coil polarity and reverse coil polarity.Refer to Terminal Arrangement and Internal Connections.Example: MKS3PN1-5 DC24---------Reverse coil polarity
3. Refer to Terminal Arrangement and Internal Connections for all wiring diagrams.


Specifications



Note: 1. The rated current and coil resistance are measured at a coil temperature of 23°C with tolerances of +15%/−20% for AC rated current and
±15% for DC coil resistance.
2. Performance characteristic data are measured at a coil temperature of 23°C.
3. The maximum voltage is one that is applicable instantaneously to the Relay coil at 23°C and not continuously.
4. For DC-operated Relays with the LED indicator built-in, add an LED current of approx. 5 mA to the rated current.

Contact Ratings




Note: 1. The values given above are initial values.
          2. Ambient temperature of models with LED indicator is −25 to 60°C.

Safety Precautions

Installation
Recommend mounting MK-S Relay so that side with wiring diagram is facing down.

Handling
Check coil polarity when wiring LED Indicator and Diode Models.

Test Button
1.Do not use the test button for any purpose other than testing. Be sure not to touch the test button accidentally as this will turn the contacts ON. Before using the test button, confirm that circuits, the load, and any other connected item will operate safely.
2.Check that the test button is released before turning ON relay circuits.
3.If the test button is pulled out too forcefully, it may bypass the momentary testing position and go straight into the locked position.Use an insulated tool when you operate the test button.
4.Models with test buttons or LED indicators fulfill the requirements for reinforced insulation between live parts and the front of cover only when the Relay is in a complete condition, i.e. with the nameplate, nameplate frame, test button, and slider in place. If any of these parts are removed, only the requirements for basic insulation are fulfilled.

Certain Precautions on Specifications and Use
1. Suitability of Use. Omron Companies shall not be responsible for conformity
with any standards, codes or regulations which apply to the combination of the
Product in the Buyer's application or use of the Product. At Buyer's request,
Omron will provide applicable third party certification documents identifying
ratings and limitations of use which apply to the Product. This information by
itself is not sufficient for a complete determination of the suitability of the Product
in combination with the end product, machine, system, or other application
or use. Buyer shall be solely responsible for determining appropriateness of
the particular Product with respect to Buyer's application, product or system.
Buyer shall take application responsibility in all cases but the following is a
non-exhaustive list of applications for which particular attention must be given:
(i) Outdoor use, uses involving potential chemical contamination or electrical
interference, or conditions or uses not described in this document.
(ii) Use in consumer products or any use in significant quantities.
(iii) Energy control systems, combustion systems, railroad systems, aviation
systems, medical equipment, amusement machines, vehicles, safety equipment,
and installations subject to separate industry or government regulations.
(iv) Systems, machines and equipment that could present a risk to life or property.
Please know and observe all prohibitions of use applicable to this Product.
NEVER USE THE PRODUCT FOR AN APPLICATION INVOLVING SERIOUS
RISK TO LIFE OR PROPERTY OR IN LARGE QUANTITIES WITHOUT
ENSURING THAT THE SYSTEM AS A WHOLE HAS BEEN DESIGNED TOADDRESS THE RISKS, AND THAT THE OMRON’S PRODUCT IS PROPERLY
RATED AND INSTALLED FOR THE INTENDED USE WITHIN THE
OVERALL EQUIPMENT OR SYSTEM.
2. Programmable Products. Omron Companies shall not be responsible for the
user’s programming of a programmable Product, or any consequence thereof.
3. Performance Data. Data presented in Omron Company websites, catalogs
and other materials is provided as a guide for the user in determining suitability
and does not constitute a warranty. It may represent the result of Omron’s
test conditions, and the user must correlate it to actual application requirements.
Actual performance is subject to the Omron’s Warranty and Limitations
of Liability.
4. Change in Specifications. Product specifications and accessories may be
changed at any time based on improvements and other reasons. It is our practice
to change part numbers when published ratings or features are changed,
or when significant construction changes are made. However, some specifications
of the Product may be changed without any notice. When in doubt, special
part numbers may be assigned to fix or establish key specifications for
your application. Please consult with your Omron’s representative at any time
to confirm actual specifications of purchased Product.
5. Errors and Omissions. Information presented by Omron Companies has been
checked and is believed to be accurate; however, no responsibility is assumed
for clerical, typographical or proofreading errors or omissions.
