TSD7 SERIES

Interval/Delay-on-BreakTimer

Description

TheTSD7 Series utilizes only two terminals connected in series

with the load. Interval timing mode period is achieved by using a

small portion of the AC sine wave allowing sufﬁcient voltage for

circuit operation. It can be used as an interval timer to control or

pulse shape the operation of contactors, solenoids, relays, and

lamp loads. TheTSD7 Series can be wired to delay on the break

of a switch for energy saving fan delays.

Operation (Interval)

Upon application of input voltage, the output energizes and the

time delay begins. The output remains energized throughout the

time delay. At the end of the time delay, the output de-energizes

and remains de-energized until power is removed.

Reset: Removing input voltage resets the time delay and

the output.

Wiring Diagram

Operation (Delay-on-Break)

Upon closure of SW1, the load is energized and the timer is

reset (zero volts across its input terminals). Opening SW1 re-

applies input voltage to the timer, the load remains energized

and the time delay begins. At the end of the time delay, the

output de-energizes. If SW1 is open when power is applied, the

load will energize for the time delay then de-energize.

Reset: Reclosing SW1 resets the timer.
