Marsh Bellofram Diversified Electronics Division TSH Series Delayed Interval Solid-State Output

Product catalog summary

Overview: The TSH Series Delayed Interval Solid-State Output timer is designed to control the timing of electrical loads. It operates by initiating an OFF time upon application of voltage, followed by an ON time, and then de-energizing the load to complete the cycle. The OFF and ON times are independently adjustable.

Specifications:

Supply Voltage: Available in 24, 120, or 240 VAC, 50/60 Hz with a tolerance of ±10%.
Output Rating: Solid-state, SPST-N.O. with a 1 amp resistive load capacity, 1250 VA inrush, and 125 VA run at 120 VAC inductive.
Timing Ranges: Virtually unlimited with standard ranges available on page 84.
Timing Tolerances: Minimum setting +0–20%, Maximum setting ±10%.
Repeatability: 1% maximum with no first cycle effect.
Reset Times: 100 mSEC before timeout, 50 mSEC after timeout.
Recycle Time: 40 mSEC.
Duty Cycle: Continuous operation.
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 0.96 oz, shipping weight is 1.28 oz.

Operation: The timer's operation involves applying voltage to initiate the OFF time, followed by the ON time, and then de-energizing the load. Resetting can be done by removing the input voltage during or after the time periods.

Model Number Example: TSH-120-AFC-015 indicates a delayed interval timer with 120 VAC supply voltage and both delays fixed at 15 seconds, UL Recognized.

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 the cycle is complete. Reset during or after the time periods is accomplished by removal of the input voltage. The OFF/ON time periods are independently adjustable.
