OPERATING CHARACTERISTICS: Permissible ambient temperature = -40°C to 125°C (-40°F to 257°F) Mechanical Life–no load = 10,000,000 operations (frequency 18,000 operations/hr) The following applies for all relays unless otherwise noted: - Operating voltage = 8–16V at 12V; 16–32V at 24V

- Contact voltage drop( 1 ) = Typ. 50MV at 10A - Insulation resistance( 1 ) = 20M 1 Min. (DC 500V)

- Operate time( 1 ) = 20ms Max. - Release time( 1 ) = 20ms Max. - Resistive load N.O. = 50A at 14V DC - Resistive load N.C. = 30A at 14V DC

- Dielectric strength N.O.( 1 ) = AC 500V, 50/60Hz 1 min - Dielectric strength N.C.( 1 ) = AC 500V, 50/60Hz 1 min - Life Expectancy Mechanical = 10,000,000 operations (frequency 18,000 operations/hr) - Life Expectancy Electrical = 100,000 operations (frequency 1,200 operations/ hr) A change over relay switches current from one user to another. Change over relays are used for switching from one horn to the fan, from forward to backward movement of the sliding roof, from opening to closing electrically operated windows and for two-stage uses such as fans and some rear window heating systems.

Change Over Relays Change over relays can be used in applications that require Change Over Relays, Normally Open Relays or Normally Closed Relays.
