2. Operating characteristics were measured at a coil temperature of 23 C. 3. The maximum allowable voltage is the maximum value of the fluctuation range for the Relay coil operating power supply and was measured at an ambient temperature of 23 C. - Page 5 The contact resistance for the auxiliary contact block (G73Z) was measured with 0.1 A at 5 VDC using the voltage drop method. 3. The operate time was measured with the rated voltage imposed with any contact bounce ignored at the ambient temperature of 23 C.
