Time Mark 335, 365 Data Sheet
TIME MARK is a division of
MODEL 335
MODEL 365
Retriggerable
One-Shot Timer
⚫ Most Common Voltage & Timing Ranges
⚫ 5-Year Unconditional Warranty
DESCRIPTION
The Model 335 and 365 Retriggerable One-Shot Timers
are functionally interchangeable. The Model 335 is a
DPDT potentiometer (knob-adjust) timer while the Model
365 is a DPDT, high-accuracy digital input timer. Solid-
state timing circuits in each model drive an internal
electromechanical relay.
With power applied to the coil, when the initiate switch (dry
contact) is closed, the relay will energize for the time
period set by the user. At the end of the preset time
period, the relay will de-energize. If the initiate switch
opens and then closes multiple times while the relay is
energized (i.e. it is “retriggered”), the relay will then restart
the delay time. The relay will remain energized until the
retriggering stops and the delay time ends. When power
is removed, the relay will de-energize.
An “SG” version of this model is available using silver with
gold flash contacts.
Models 335 and 365 are UL Recognized and CSA
Certified.

READ ALL INSTRUCTIONS BEFORE INSTALLING, OPERATING OR SERVICING THIS DEVICE.
KEEP THIS DATA SHEET FOR FUTURE REFERENCE.
GENERAL SAFETY
POTENTIALLY HAZARDOUS VOLTAGES ARE PRESENT AT THE TERMINALS OF THE MODEL 335 OR 365.
ALL ELECTRICAL POWER SHOULD BE REMOVED WHEN CONNECTING OR DISCONNECTING WIRING.
THIS DEVICE SHOULD BE INSTALLED AND SERVICED BY QUALIFIED PERSONNEL.
Installation Instructions
OPERATION
With power applied to the coil, the relay will energize for
the time period set by the user when the initiate switch
(dry contact) is closed. At the end of the preset time
period, the relay will de-energize. If the initiate switch
opens and then closes multiple times while the relay is
energized (i.e. it is “retriggered”), the relay will then restart
the delay time. The relay will remain energized until the
retriggering stops and the delay time ends. When power
is removed, the relay will de-energize.
An LED on top of the unit provides a quick visual indicator of
the relay’s status.

PIN DIAGRAM
The Models 335 and 365 One-Shot Timers require a standard
11-pin socket for mounting, and use a standard pin
configuration. Refer to the pin diagram below, or on the
timer, for terminal connections.
