• Manufacturer: Teledyne Technologies Incorporated.

FR75-1 40
NOTES:
1. For input voltages greater than 6 volts, use an external resistor in
2. Unless otherwise specified: conformance testing is at room
3. With a shorted load condition, system inductance shall be limited to
4. Relay input voltage transitions should be less than 1.0 millisecond.
5. Maximum load current ratings are with the relay in free air and
6. Loads may be attached to either the positive or negative output
7. Timing is measured from the input voltage transition to the 10% or
8. Hermeticity is not a requirement.
