Multiple Timing Modes: The 407B is available with selectable ON-Delay,
OFF-Delay or Interval timing modes. These timing modes energize a set of
DPDT output contacts. When in the ON-Delay mode, the 407B begins tim-
ing when the timer is energized. In ON-Delay mode, the contacts transfer
at time out. When in the OFF-Delay mode, the 407B begins timing when
the Start input is de-energized. In OFF-Delay mode, the contacts transfer
at time out. When in the Interval mode, the contacts transfer when the
timer is energized. In Interval mode, the contacts release at time out.
Universal Power Supply: All 407B timers can be powered using 24-240
VAC or 24 VDC power, greatly simplifying ordering and inventory manage-
ment of replacement units.
High Accuracy: The 407B’s timing circuit is not a simple RC circuit. It
utilizes the sophistication of a proprietary integrated circuit that includes
counting technology along with a stable oscillator to provide repeatable
time delays.
1/16 DIN Housing: The 48mm
tight when panel mounted. The 407B is mounted in an 11-pin round socket. With
an optional mounting clip, the 407B can be panel mounted.
The Dial on the 407B is extra large and is easy to read. When fractional ranges are select-
ed, decimal points are clearly indicated.
The Mode select and Range select switches are located on the
side of the unit, so that when panel mounted, these switches are
not accessible to the operator. This tamper proof feature prevents
unauthorized or hazardous changes to the timing mode and
range from being made.
Cycle Progress Indication: The 407B LED indicator provides a
unique and effective method of cycle progress indication. Off
before timing, the LED blinks at an ever increasing rate as the
cycle progresses; once every 3-1/2 seconds during the first 10%
of the cycle, twice during the second 10%, and so on. At time
out, the LED pulses at a high rate. (In the 1, 5, 10 and 50 second
ranges, the LED is OFF before timing, steady ON during timing,
and pulsing ON after time-out).
Timing begins when the start switch is closed (ON-delay and INT
modes) or opened (OFF-delay mode). This starts an oscillator
which runs at a frequency determined by the time setting. A fixed
number of counts from the oscillator determines the end of the
timing cycle. The time required to accomplish this depends upon
the oscillator frequency. During timing, An LED located on the
dial face blinks. For the first 10% of the cycle, the LED repeatedly
blinks once followed by a pause. For the second 10%, it blinks
twice and so on indicating the cycle progress. The LED flashes
rapidly and continuously after time out.
ON-DELAY MODE: At time out, the DPDT relay transfers its con-
tacts. These contacts remain transferred until the start switch is
opened or power is removed by some other means.
INTERVAL MODE: When the start switch is closed, the DPDT
relay transfers its contacts. The contacts remain transferred until
time out. The timer will not start again until the start switch is
opened or power is removed by some other means. The 407B
then resets and is ready for another cycle.
OFF-DELAY MODE: Power must be applied to the timer before
and during timing (terminals #10 & 2). Upon closure of the start
switch, the DPDT relay transfers its contacts. The timing begins
when the start switch is opened. The relay remains energized dur-
ing timing. At time out, the relay de-energizes.

(1/16 DIN) housing is compact and is water-
• Selectable ON-Delay/OFF-Delay/Interval Timing Modes
• Separate Start Input
• Output Contacts rated 10A at 120/240 VAC and 30 VDC
• Six Timing Ranges in a single unit
• 1 and 10 SEC, MIN, and hours
• Universal Power Supply; 24-240 VAC and 24 VDC
• 48mm
• Large and easy to read dial shows decimal points
• Round (octal) socket mount or mount in panel cutout
• Watertight when panel mounted

• Unique flashing cycle progress indication
Special note for Off-Delay operation: When operated from AC, the start switch must be of a
dry contact type such as a relay contact or mechanical switch. When operated from DC, the
start switch can be a dry contact type such as a relay contact or mechanical switch. In addition,
a solid-state device may be used as long as its saturation voltage drop is less than 1.5 VDC at
50mA.
