Multiple Timing Modes
The 407 is available with selectable OnDelay, OFF-Delay or Interval timing modes. These timing modes energize a set of DPDT output contacts. When in the ON-Delay mode, the 407 begins timing when the timer is energized. In ON-Delay mode, the contacts transfer at time out. When in the OFF-Delay mode, the 407 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
Timer can be powered using 12 VDC power, greatly simplifying ordering and inventory management of replacement units.
High Accuracy
The 407'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 407 is mounted in an 11-pin round socket. With an optional mountingclip, the 407 can be panel mounted. The Dial on the 407 is extra large and is easy to read. When fractional ranges are selected, 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 407 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).
Operations
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 he cycle progress. The LED flashes rapidly and continuously after time out.
ON-Delay Mode
At time out, the DPDT relay transfers its contacts. 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 during timing. At time out, the relay de-energizes.
