Instantaneous
The instantaneous contacts transfer as soon as the timer is powered.
Universal Power
405 timer can be powered using 24-240 VAC or 24 VDC power, greatly simplifying ordering and inventory management of replacement units.
1/16 DIN Housing
The 48 mm² (1/16 DIN) housing is compact design. The 405 is mounted in an 8-pin round (octal) socket. With an optional mounting clip, the 405 can be panel mounted. The Dial on the 405 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 405 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 5 and 50 Second ranges, the LED is Off before timing, steady On during timing, and pulsing On after time-out).
Timing begins when the start switch is closed. 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, LED repeatedly blinks once followed by a pause. For the Second 10%, it blinks twice and so on indicating the cycle progress. The LED flashes rapidly and continuously after time out
