T3M Series
The T3M Series is a Delay On Break time delay
relay featuring easy to program multiple time
ranges and digital time selection with extremely
high accuracy and repeatability. Programming is
accomplished using a 5 position rotary switch
to select one of five time ranges. A 3-digit pushbutton switch selects the amount of time delay
required.

Operating Logic: Voltage is continuously
applied to the timer. Depending upon the model,
either a switch closure or application of control
voltage* causes the relay coil to be energized and
remain so as long as the switch is held closed
or control voltage is applied. Opening the switch
or removing the control voltage starts the timing
cycle. At the end of the preset time delay, the
relay coil de-energizes and the timer is ready for
a new timing cycle. If the start switch is re-closed
or control voltage is reapplied during timing, the
timer will reset and will not start timing until
the start switch is opened or control voltage is
removed. Control leads should be shielded when
close to other leads.
