Marsh Bellofram Automatic Timing & Controls 405A Series Timer with Instantaneous Relay - 1

405A Series Automatic Timing & Controls automatictiming.com 800.727.5646 221/16 DIN Timers // 405A Series Instantaneous & Delayed: A version of the 405A is available with one set of SPDT instantaneous contacts and one set of SPDT delayed contacts. The instantaneous contacts transfer as soon as the timer is powered. The delayed contacts transfer at time out. This contact arrangement can be used to replace many conventional timers. On Delay/Interval Timing Mode Version: A version of the 405A is available with selectable ON-delay or Interval timing modes. This version has a set of DPDT output contacts. When in the ON-delay mode, the contacts transfer at time out. When in the Interval mode, the contacts transfer when power is applied and release at time out. Universal Power: All 405A timers 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 48mm2 (1/16 DIN) housing is compact and is watertight when panel mounted. The 405A is mounted in an 8-pin round (octal) socket. With an optional mounting clip, the 405A can be panel mounted. The Dial on the 405A 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 405A 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). 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. MODEL...F1X The instantaneous contacts (3-1-4) transfer immediately after the start switch is closed. The delayed contacts (6-8-5) transfer after the timing cycle indicated on the front dial setting. Both contacts remain transferred until the unit is reset. MODEL...F2X 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. The 405A then resets and is ready for another cycle. 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 405A then resets and is ready for another cycle.
