MODEL 331
MODEL 361
Release Delay Timers
⚫ Solid-State Design
⚫ Multiple Voltage & Timing Ranges
⚫ 5-Year Unconditional Warranty
DESCRIPTION
The Models 331 and 361 Release Delay Timers are
designed for a wide usage in new or replacement industrial
applications. Examples include delay-off circuits, batch
processing circuits, and other applications requiring a
remote-triggered, off-delay timer.
The Model 331 is a DPDT potentiometer (knob-adjust)
timer. The Model 361 is a DPDT, high-accuracy digital
input timer. Solid-state timing circuits in each model drive
an internal electromechanical relay.
Each model is functionally interchangeable. They are
available in a variety of voltage and timing ranges to cover
any application.
An “SG” version of this model is available using silver with
gold flash contacts.
Models 331 and 361 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 MODELS 331 OR 361.
ALL ELECTRICAL POWER SHOULD BE REMOVED WHEN CONNECTING OR DISCONNECTING WIRING.
THIS DEVICE SHOULD BE INSTALLED AND SERVICED BY QUALIFIED PERSONNEL.
Installation Instructions
OPERATION
Supply voltage must be constantly applied. When the
control switch is closed, the internal relay will energize.
Timing begins when the control switch is opened. The
delay can be reset by reclosing the control switch. On
completion of the delay, the relay will de-energize.
PIN CONNECTIONS
The Models 331 and 361 Release Delay 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.
The external control
switch must be a dry contact. DO NOT APPLY POWER
TO PINS 5 AND 6. The external control switch can be a
maximum of 10 feet away. The recommended wire is 22
gauge.
An LED on top of the unit provides a quick visual indicator of
the relay’s status.
