304G Solid-State Percentage Timer

About the 304G Solid-State Percentage TimerĀ  from the Automatic Timing and Controls division of Marsh Bellofram Corporation:

  • High Accuracy
  • Convenient Adjustment
  • Cycle Progress Indication

The 304G solid-state percentage timer comes standard in a 120 sec range with 15 sec, 30 sec, 60 sec user configurable ranges. Additionally, all second ranges can become minute ranges by cutting jumper J0. The 304G is easily panel mounted with 4 screws. It utilizes an integrated circuit technology for high accuracy timing.

CONTACTS: The relay contact is capable of switching 10 A to a resistive 120 VAC or 30 VDC load. It is capable of driving a 1/3 HP load at 120 VAC.

CYCLE PROGRESS INDICATION: The 304G has a pilot light that is on solid during the relay off time. It blinks at a faster rate during the relay on time: once every 3.5 seconds during the first 10% of the cycle, twice during the second 10% and so on.

HIGH ACCURACY: The 304G’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.

CONVENIENT ADJUSTMENT: Graduated in easily read 1% increments, the 304G provides continuous adjustment of on time between 5 and 95%.
