Coil Ratings

Set Coil

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 AC coil resistance values are reference values.
          4. The maximum voltage is one that is applicable instantaneously to the Relay coil at an ambient temperature of
               23°C and not continuously.
* Values in parentheses are for open relays.

Reset Coil

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 AC coil resistance values are reference values.
          4. The maximum voltage is one that is applicable instantaneously to the Relay coil at an ambient temperature of
               23°C and not continuously.

Coils (Conforming to Auxiliary Power Relay 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. The AC coil resistance and coil inductance values are for reference only.
          3. Performance characteristic data are measured at a coil temperature of 23°C.
          4. The maximum voltage is one that is applicable instantaneously to the Relay coil at an ambient temperature of
               23°C and not continuously.

Contact Ratings

Standard Relays

DC-switching Relays

Note: 1. When switching DC inductive loads at 125 V or more, an unstable region exists for a switching current of between
              0.5 and 2.5 A. The Relay will not turn OFF in this region. Use a switching current of 0.5 A or less when switching
              125 VDC or more.
           2. If L/R exceeds 7 ms when switching DC inductive loads, an arc-breaking time of up to 50 ms must be considered
                in application and the circuit must be designed to ensure that an arc-breaking time of 50 ms is not exceeded.
*1. Refer to Switching an Switching an AC Load with a DC-switching Model ("X" Model) on Data Sheet.

Contacts (Conforming to Auxiliary Power Relay Specifications)

Note: 1. When switching DC inductive loads at 125 V or more, an unstable region exists for a switching current of between
              0.5 and 2.5 A. The Relay will not turn OFF in this region. Use a switching current of 0.5 A or less when switching
              125 VDC or more.
           2. If L/R exceeds 7 ms when switching DC inductive loads, an arc-breaking time of up to 50 ms must be considered
                 in application and the circuit must be designed to ensure that an arc-breaking time of 50 ms is not exceeded.

Characteristics

*1. The data shown above are initial values.
*2. The contact resistance was measured with 1 A at 5 VDC using the voltage drop method.
*3. The set or reset time was measured with the rated voltage imposed with any contact bounce ignored at an ambient
       temperature of 23°C.
*4. The insulation resistance was measured with a 500-VDC megger applied to the same places as those used for
       checking the dielectric strength.
*5. The electrical endurance was measured at an ambient temperature of 23°C.
*6. This value was measured at a switching frequency of 60 operations per minute.
