Power Relays
MK-S(X)
MK-S-series Relays with DC-switching
Models That Can Switch 220 VDC, 10 A
(Resistive Load).
• Switch a DC load of 220 VDC, 10 A (resistive load).
• Models for AC Loads can switch 250 VAC, 15 A (resistive load).
• Lineup includes models with SPST-NO and SPST-NO/SPST-
NC contact forms.
• Using a SPST-NO/SPST-NC contact form enables detecting
contact welding. (When the NO contacts become welded, the
NC contacts will maintain a minimum distance of 0.5 mm.)
• Models available with operation indicators and built-in test
buttons.
• RoHS compliant.
• Standards: UL, IEC (TÜV certification)
For the most recent information on models that have been certified for
safety standards, refer to your OMRON website.

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 allowable voltage is the maximum value of the allowable voltage range for the operating power supply for the relay coil.
There is no continuous allowance.
4.
The rated current is approximately 5 mA higher for Models with Built-in Operation Indicators (DC operating coils).

Note:
If the L/R of an inductive load exceeds 7 ms with a Model for a DC Load, the arc interruption time must be less than approximately 50 ms
to use the Relay. Design the circuit so that the arc interruption time is 50 ms or less.

*1.
The contact resistance was measured for 1 A at 5 VDC using the voltage drop method.
*2.
The operate time was measured with the rated voltage imposed and any contact bounce ignored at an ambient temperature of 23°C.
*3.
The insulation resistance was measured with a 500-VDC insulation resistance tester at the same places as those used for checking the
dielectric strength.
*4.
The electrical endurance was measured at an ambient temperature of 23°C.
