Time Delay Relays

Dedicated - Delay-on-Break

TSDB SERIES

Description

TheTSDB Series is designed for more demanding commercial

and industrial applications where small size, and accurate

performance are required. The factory calibration for ﬁxed

time delays is within 1% of the target time delay. The repeat

accuracy, under stable conditions, is 0.5% of the time delay.

TheTSDB Series is rated to operate over an extended

temperature range. Time delays of 0.1 seconds to 1000 minutes

are available. The output is rated 1A steady and 10A inrush. The

modules are totally solid state and encapsulated to protect the

electronic circuitry.

Operation (Delay-on-Break)

Input voltage must be applied before and during timing. Upon

closure of the initiate switch, the output energizes. The time

delay begins when the initiate switch is opened. The output

remains energized during timing. At the end of the time delay,

the output de-energizes. The output will energize if the initiate

switch is closed when input voltage is applied.

(Positive Switching)

N/L2

Reset: Reclosing the initiate switch during timing resets the time

delay. Loss of input voltage resets the time delay and output.
