User manual OMRON G4Q DATASHEET

[. . . ] Ratchet Relay G4Q Unique Ratchet Mechanism Assures Positive Alternate Transfer/Switching Operation · Each contact in the double-pole contact mechanism performs alternate make-brake operation at each pulse input and is thus ideal for alternate operation or transfer/switching operation of a motor. · Positive operation is assured due to the unique ratchet mechanism. · Satisfies dielectric strength of 2, 000 VAC. [. . . ] Performance characteristic data is measured at a coil temperature of 23°C. The maximum voltage is one that is applicable instantaneously to the Relay coil at an ambient temperature of 23°C and not continuously. The AC power consumption is measured at 60 Hz.

The contact resistance was measured with 0. 1 A at 5 VDC using the voltage drop method. The operate time was measured with the rated voltage imposed with any contact bounce ignored at an ambient temperature of 23°C. The insulation resistance was measured with a 500-VDC megger applied to the same places as those used for checking the dielectric strength. The electrical endurance was measured at an ambient temperature of 23°C. This value was measured at a switching frequency of 60 operations per minute.
