Product Details

Avoid damaging pump cycling due to pressure surges. We stock three versions of Time Mark time delay relays: the 330/360 "operate delay" relays, the 361 "release delay" relays and the 362 "interval timer" relays. Adjust the timer range for the required time delay with either a knob or 10 binary switches, depending on model.  330/360 Series "Operate Delay" Relays: The time delay begins when the supply voltage is applied. Upon completion of the delay, the internal relay will energize and remain so until the supply voltage is removed.  361 Series "Release Delay" Relays: The supply voltage must be constantly applied. When a control switch (i.e., pushbutton) is closed, the internal relay will energize. When you release the control switch, timing begins and the relay will stay closed until it times out.   362 Series "Interval Timer" Relays: The relay is energized for a specific length of time after the supply voltage is applied to the timer. The supply voltage must be removed to reset the timer.   Note: Order sockets separately.
