Transient voltage limits (output): In accordance with MIL-STD-461 (methods CE106 and RE103),
voltage spikes generated by time delay relays shall not exceed 42 volts during the following time
periods starting at the instant of opening of the relay coil circuit:
PIN's with a suffix letter W: 50 microseconds.
PIN's with a suffix letter A: 500 microseconds.
Monitoring of spike voltages shall be by a device (such as a memory type oscilloscope) that can detect,
measure, display, and record 0.25 to 1000 volts over the applicable time durations specified herein.
Switches used to control the time delay relays during voltage-spike measurements shall not be EMI
suppressed.
Time current relay characteristics at 25C: 6/ Relays shall sustain five applications (make and carry
only) of power concurrently on adjacent poles at each of five different current levels for the time
durations shown in table IV. Separate relays shall be tested at 28 V dc and 115/200 V ac, 400 Hz, 3
phase. Cooling time between successive applications shall be 30 minutes. The test shall be performed
on both normally open and normally closed contacts of each relay. There shall be no failures or
evidence of welding or sticking, and relays shall pass contact voltage drop at conclusion.
