ATC, 304G-004-Q-00-XX, 304G Series Solid-State Percentage Timer 15 Second Range, 120 VAC and Srandart Dial Calibration
Features:
- High Accuracy
- Convenient Adjustment
- Cycle Progress Indication
- 15 Second Range
- 120 VAC
- Srandart Dial Calibration
The 304G solid-state percentage timer comes standard in a 120 Sec range with 15 Sec range. Additionally, Second range 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%. The 304G comes standard in the 120 Sec range but is user configurable for the 15 Sec by changing jumpers on the PC board. This range 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.
