Technical content

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.
