Safety Relay G7SA (Part Numbers)

Safety Relay G7SA

OMRON

OMRON

A power relay with a high capacity and high dielectric strength that can handle momentary voltage drops.
[Features]
·Wiring work is quicker than conventional screw terminals with the new push-in plus terminal block sockets now available in the product series (Wiring labor-hours are approx. 60% shorter than traditional screw tightening terminals.).
·Relay with forcibly guided contacts (EN/IEC 61810-3 VDE certified).
·Supports the CE marking of machinery (Machine Directive).
·Helps avoid hazardous machine status when used as part of an interlocking circuit.
·Available in 4-position and 6-position.
·Terminal arrangement simplifies PWB pattern design.
· Reinforced insulation between inputs and outputs. Reinforced insulation between some poles of different polarity.
[Applications]
·Helps avoid hazardous machine status when used as part of an interlocking circuit.

Note 1: The values given above are initial values.
　Note 2. Performance characteristic data is measured at a coil temperature of 23°C.
*1. Measurement conditions: 5 V DC, 1 A, voltage drop method.
*2. Measurement conditions: rated voltage operation
Ambient temperature conditions: 23°C
Bounce time not included.
*3. The response time is the time it takes for the a-contacts to open (OFF) after the coil voltage is turned OFF. Contact bounce time is included.
Measurement conditions: rated voltage operation
Ambient temperature conditions: 23°C
*4. Measured with a 500 V DC ohmmeter at the same places that the dielectric strength was checked.
*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 V AC, 50/60 Hz for 1 min. When using Push-In Plus terminal sockets (P7SA-□FND-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 data.
*8. Inductive load - AC15: cosø = 0.3, DC13: L/R = 48 ms.
*9. This value is based on a switching frequency of 300 operations/min.
*10. 12 to 48 V DC: 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. 110 V DC: 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.
