Timing Specifications
Timing Modes —
On-Delay, Off-Delay, Interval and
Accumulating On-Delay.
Timing Ranges — 6 to 180 cycles;
0.1 to 3 / 0.5 to 15 / 1 to 30 / 2 to 60 /
4 to 120 / 6 to 180 / 10 to 300 sec.;
0.33 to 10 / 0.5 to 15 / 1 to 30 min.;
1 to 6 / 2 to 48 hr. (All are +5%, –0% of
maximum values).
Timing Adjustment — Knob or fixed
time (internal fixed resistor) – all mod-
els; customer supplied external poten-
tiometer or resistor – On-Delay and
Interval models only.

operating temperature and voltage
ranges.
Reset Time — 30 ms. min. (between
deenergization and reenergization with-
out affecting accuracy.)
Relay Operate Time — Off-Delay
mode: 35 ms.; Interval mode — 20 ms.
Relay Release Time — On-Delay
and Accumulating On-Delay modes —
