Safety Relay G7SA
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.
