PUSH BUTTON START/INTERNAL: The 409 has a Push Button built into

its front dial. When pressed, the timer starts and provides an interval

time delay. The 409 has a set of DPDT output contacts. When the Push

Button is pressed with power applied, the contacts immediately transfer.

After the timer has timed out, the contacts release. Unit timing will reset

with power loss.

UNIVERSAL POWER SUPPLY: All 409 timers can be powered using

24-240 VAC or 24 VDC power, greatly simplifying ordering and inventory

management of replacement units.

HIGH ACCURACY: The 409’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 48mm2 (1/16 DIN) housing is compact. The

409 is mounted in an 8-pin round (octal) socket. With an optional

mounting clip, the 409 can be panel mounted.

The dial on the 409 is extra-large and is easy to read. When fractional

ranges are selected, decimal points are clearly indicated.

The Range Select Switch is located on the side of the unit, so that when

panel mounted, this switch is not accessible to the operator. This tamper

proof feature prevents unauthorized or hazardous changes to the timing

range from being made.

Timing begins when the front green push button is pressed. This ener-

gizes the DPDT relay and starts an oscillator which runs at a frequency

determined by the time setting. A fixed number of counts from the oscil-

lator determines the end of the timing cycle.

The LED indicates the status of the relay output. It comes on when the

green push button is pressed and remains on steady during the cycle.

The LED turns off after the cycle is completed and the contacts released.
