Time Mark 334, 364 Data Sheet

TIME MARK is a division of

MODEL 334

MODEL 364

Delayed One-Shot

Timer

⚫ Most Common Voltage & Timing Ranges
⚫ 5-Year Unconditional Warranty

DESCRIPTION

The Model 334 and 364 Delayed One-Shot Timers are

functionally interchangeable. The Model 334 is a DPDT

potentiometer (knob-adjust) timer while the Model 364 is a
DPDT, high-accuracy digital input timer. Solid-state timing

circuits in each model drive an internal electromechanical

relay.

Upon application of power, the unit will start the OFF
delay. After the OFF delay times out, the relay will
energize for the ON time. When the ON time expires, the

relay will de-energize and all timing will stop. Power must
be removed and reapplied to begin timing again.

An “SG” version of this model is available using silver with

gold flash contacts.

Models 334 and 364 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 334 OR 364.

ALL ELECTRICAL POWER SHOULD BE REMOVED WHEN CONNECTING OR DISCONNECTING WIRING.

THIS DEVICE SHOULD BE INSTALLED AND SERVICED BY QUALIFIED PERSONNEL.

Installation Instructions

OPERATION

When the supply voltage is applied, the OFF cycle begins
timing. Upon completion of the delay, the internal relay
energizes and the ON cycle begins timing (ON and OFF
cycles can be of equal or unequal durations). When the

ON time expires, the relay will de-energize and all timing

will stop. Power must be removed and reapplied to begin

timing again.

PIN DIAGRAM

The Models 334 and 364 Delayed One-Shot Timers
require a standard 8-pin socket for mounting, and use a

standard pin configuration. Refer to the pin diagram

below, or on the timer, for terminal connections.

An LED on top of the unit provides a quick visual indicator of

the relay’s status.
