304G-400-Q-00-XX

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. IND. CONT. EQ. 101F E48329 Solid-State Percentage Timer CONVENIENT ADJUSTMENT: Graduated in easily read 1% increments, the 304G provides continuous adjustment of on time between 5 and 95%. OPERATION SPECIFICATIONS The 304G comes standard in the 120 SEC range but is user ­configurable for the 15 SEC, 30 SEC or MIN., 60 SEC or MIN. by changing jumpers on the PC board. Each of these ranges can also be made ­minutes range by changing a jumper. Its solid-state circuitry repeatedly closes the SPST load switch for a percentage of the time cycle, as set on the timer dial, and opens it for the ­remainder of the cycle. When the dial pointer is set below 3%, the load switch stays open for the full cycle; it remains closed when the pointer is set above 98%. This is true for all seconds ranges. Minute ranges have a 0.01% minimum. If power is interrupted to the timer it will reset. When power is restored, the timer will begin a new time cycle. MODEL NUMBER MODEL NUMBER PERCENTAGE TIMER 304G Series 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 changing jumper J11 . The 304G is easily panel ­mounted with 4 screws. It utilizes an integrated circuit ­technology for high accuracy timing. 304G Q 00 RANGE Multi-range, Jumper Selectable* 15/30/60/120 SEC or MIN *Factory Set to 120 Sec Range 15 SEC 30 SEC 60 SEC 400 004 006 007 VOLTAGE & FREQUENCY 120 VAC, 50/60 Hz MODEL 304G Non Plug-In CONTACT RATINGS (non-inductive) 10A at 120 VAC TEMPERATURE RATING 32° to 120°F (0° to 50°C) SETTING ACCURACY ±5% of range 5 to 95% on time, in 1% graduations.
