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 tamperproof 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 thegreen push button is pressed and remains on steady during the cycle.The LED turns off after the cycle is completed and the contacts released.
