Marsh Bellofram Diversified Electronics Division TSF Series Repeat Cycle OFF-Time First Solid-State Output

Product catalog summary

Overview: The TSF Series is a solid-state output timer designed for repeat cycle operations with independently adjustable OFF and ON time periods. It is suitable for applications requiring precise timing control.

Specifications:

Timing Ranges: Virtually unlimited, with standard ranges available on page 84.
Output Rating: Solid-state, SPST-N.O. 1 amp resistive; 1250 VA inrush, 125 VA run at 120 VAC, inductive.
Timing Tolerances: Minimum setting +0–20%, Maximum setting ±10%.
Repeatability: 1% maximum, no first cycle effect.
Reset Times: 100 mSEC before time out, 50 mSEC after time out.
Supply Voltage: Options include 24, 120, or 240 VAC, 50/60 Hz, with a tolerance of ±10%.
False Transfer: No false transfer occurs.
Enclosure: Surface mounted and encapsulated with high-quality epoxy for environmental protection.
Temperature Rating: Operating range from 32° to 131°F (0° to +55°C), storage range from -49° to 185°F (-45° to +85°C).
Terminations: 1/4" quick disconnect terminals.
Weight: Net weight is 1.28 oz, shipping weight is 1.6 oz.

Model Number Configuration: The model number is structured to indicate supply voltage, type of operation, and delay period. For example, TSF-24-ARC-300 indicates a repeat cycle with 24 VAC and both delays adjustable from 3 to 300 seconds.

Operation: The timer initiates the OFF time upon application of voltage. After the OFF time, the load energizes, starting the ON time. This cycle repeats until voltage is removed.

800.727.5646 atcdiversified.com Diversified Electronics TSF Series Solid-State Output // TSF Series 91 Repeat Cycle OF F - Time Fi r s t So l i d - S ta t e Ou t p ut Application of voltage to the input of the timer initiates the OFF time. Upon completion of the OFF time, the load energizes and the ON time begins. Upon completion of the ON time, the load de-energizes and one cycle is completed. This OFF/ON cycling continues until voltage is removed from the input. The OFF/ON time periods are independently adjustable. \\\WIRING \\\DIMENSIONS (INCHES) \\\SPECIFICATIONS TIMING RANGES Virtually unlimited. See page 84 for standard ranges available.
