  • CP Series Timer

    For continuous ON-OFF control of electrical circuits, the Model CP single circuit repeat cycle timer is a continuous cycling control where the ON or circuit closure time is dial adjusted for a percentage of the total time cycle.

    Applications:

    • Control of Pumps
    • Blowers
    • Filters
    • Heating Equipment
    • Industrial Ovens
    • Laboratory Equipment
    • Where ON or OFF control is desired as a percentage of the primary fixed total time cycle.

    Features:

    • Precise Fool-proof Operating Mechanism
    • Eliminates All Engaging Cams And Latches
    • Five Time Ranges From Which To Choose
    • Minimal Panel Space Needed

  • 304 Percentage Timer

    Easily the most rugged and dependable of industrial percentage timers, the ATC 304 incorporates heavy-duty contacts that are capable of switching loads as large as 4.6 KW directly.

    Large Contacts: Self-cleaning silver contacts are 3/8 inch in diameter, larger than in any other make of percentage timer. They easily provide 1,000,000 operations at the full rated load of 25 A (non plug-in models).

    Rugged and Trouble-Free: Every component of the 304 has been refined and improved over the years to provide dependable operation for at least 3,000,000 cycles. Its classic simplicity of design makes it virtually trouble-free.

    Convenient Adjustment: Graduated in easily read 1% increments, the 304 provides continuous adjustment of on time between 5 and 95%. It also switches the load off continuously when the pointer is set below 3%; and on continuously, when the pointer is set above 98%.

    Typical Applications: Ideal for controlling wattage input to electrically heated equipment, the 304 non-plug-in models can pulse loads up to 4.6 KW directly through the SPST load switch; the plug-in models can switch up to 2.3 KW loads directly.
    The 304 can be used with other types of electrical equipment to control the ratio of on time and off time in a fixed time cycle. In many types of ratio and cascade control systems, the 304 provides rate-of-rise set point drive control; special dial calibrations are available for this application.

    Features:

    • Classic design
    • Convenient, continuous adjustment
    • Available in choice of 15, 30, and 60 sec. time cycles. 60 Hz
    • 3/8″ self cleaning silver contacts

  • 304G Solid-State Percentage Timer

    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%.

    Features:

    • High Accuracy
    • Convenient Adjustment
    • Cycle Progress Indication

  • 304GX Solid-State Percentage Timer

    The 304GX operates like the 304G, only with cycle progress memory and a latching relay. The 304GX saves progress when power is removed, and will resume timing when power is reapplied. The relay only changes state when the cycle reaches the set point or the end of the cycle.

    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 304GX 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 3.2 seconds during the first 10% of the cycle, twice during the second 25% and so on.

    High Accuracy: The 304GX’s timing circuit is not a simple RC circuit. It utilizes the microprocessor that includes counting technology along with a stable crystal oscillator to provide repeatable time delays.

    Convenient Adjustment: Graduated in easily read 1% increments, the 304GX provides continuous adjustment of on time between 5 and 95%.

    Features:

    • Cycle Progress Memory
    • Latching Relay
    • High Accuracy
    • Convenient Adjustment
