ATC-Automatic Timing & Control 409B Series Data Sheet
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.
OPERATIONS
Timing begins when the front green push button is pressed. This energizes the DPDT relay and 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 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.
