Note: 1. The above values are initial values.
           2. Performance characteristics are based on coil temparature of 23°C.
*1. The contact resistance was measured with 1 A at 5 VDC using the voltage-drop method.
*2. These times were measured at the rated voltage and an ambient temperature of 23°C. Contact bounce time is not
       included.
*3. The response time is the time it takes for the normally open contacts to open after the coil voltage is turned OFF.
       Contact bounce time is included. Measurement conditions: Rated voltage operation, Ambient temperature: 23°C
*4. The insulation resistance was measured with a 500-VDC megohmmeter at the same locations as the dielectric
       strength was measured.
*5. Pole 3 refers to terminals 31-32 or 33-34, pole 4 refers to terminals 43-44, pole 5 refers to terminals 53-54, and
       pole 6 refers to terminals 63-64.
*6. When using a P7SA Socket, the dielectric strength between coil contacts/different poles is 2,500 VAC, 50/60 Hz for
       1 min. When using Push-In Plus terminal sockets (P7SA-[]F-ND-PU), the dielectric strength between coil contacts
       as well as between different poles is 4,000 VAC, 50/60 Hz for 1 min.
*7. The durability is for an ambient temperature of 15 to 35°C and an ambient humidity of 25% to 75%. For the durability
       performance to the load, refer to the Durability Curve.
*8. AC15: cosφ = 0.3, DC13: L/R = 48-ms.
*9. The failure rate is based on an operating frequency of 300 operations/min.
*10. 12 to 48 VDC:
       When operating between 70 and 85°C, reduce the rated carry current of 6 A by 0.1 A for each degree above 70°C. 
  (See Fig. 1.)
       110 VDC:
       When operating between 40 and 60°C, reduce the rated carry current of 6 A by 0.27 A for each degree above 40°C.
