Bellofram Precision Controls
Time Delay Relays
Surface Mount Solid State Relays
Surface mount solid state relays are lightweight and compact, facilitating their installation within space constrained environments, or where space may be at a premium.
TSA Series Interval Solid-State Output
When voltage is applied to the input terminals, the load energizes and the time delay begins. Upon completion of the delay period, the load de-energizes. Reset during or after the delay period is accomplished by removal of the input voltage. The TSA Series is a two input terminal device that connects in series with the input and load.
TSB Interval Solid-State Output Timers
The TSB series from the ATC Diversified Electronics division of Marsh Bellofram is a family of rugged, high-reliability interval solid-state output time delay relays (TDRs). The time delay begins when power is applied to the timer. Upon completion of the delay period, the load de-energizes. Reset during or after the delay period is accomplished by removal of the input voltage.
TSC ON-Delay Solid-State Output TDR
The TSC Series from the ATC Diversified Electronics division of Marsh Bellofram is a family of rugged, high-reliability ON-delay solid state output time delay relays (TDRs), available in both fixed and adjustable time versions. The time delay begins when power is applied to the timer. Upon completion of the delay period, the load energizes. Reset during or after the delay period is accomplished by removal of the input voltage. The TSC will not false transfer if voltage is removed prior to completion of the delay period. A fast recycle time permits accurate, high speed, continuous operation.
TSD OFF-Delay Solid-State Output Timer
The TSD Series from the ATC Diversified Electronics division of Marsh Bellofram is a family of rugged, high-reliability OFF-delay solid state output time delay relays (TDRs), available in both fixed and adjustable time versions. An external isolated switch controls the timer. When closed (momentary or maintained), the load energizes and the delay period begins. Upon completion of the delay period, the load de-energizes.
TSE Single Shot Solid-State Output TDR
The TSE Series from the ATC Diversified Electronics division of Marsh Bellofram is a family of rugged, high-reliability single shot solid state output time delay relays (TDRs). The distinguishing feature of this series is its single shot switch mechanism, which requires only a brief closure of an initiating switch to active the timer interval.
TSF Repeat Cycle-OFF Time First
TSF Repeat Cycle-OFF Time First Solid-State Output Timer. 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.
TSG Repeat Cycle-ON Time First
TSG Repeat Cycle-ON Time First Solid-State Output. Application of voltage to the input of the timer energizes the load and initiates the ON time. Upon completion of the ON time, the load de-energizes and the OFF time begins. Upon completion of the OFF time, the load energizes and one cycle is completed. This ON/OFF cycling continues until voltage is removed from the input. The ON/OFF time periods are independently adjustable.
TSH Series Delayed Interval
TSH Series Delayed Interval Solid-State Output Timer. 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 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. TSH Series Delayed Interval Solid-State Output Timer
TSM Energy Conservation Timer
TSM Energy Conservation Timer Solid-State Output. When voltage is applied to the input, the internal relay picks up and the time delay begins regardless of the position of the control switch. With the switch in the open position, when voltage is applied, the timer will complete its time delay period and the internal relay will drop out if the switch is not closed before the completion of the time delay period. With the switch in the closed position, when voltage is applied, the timer will complete its time delay period and the internal relay will drop out if the switch is not opened and reclosed before the completion of the time delay period. After voltage has been applied, closing of the control switch initiates the time delay period. Reset is accomplished by interrupting the supply voltage or re-closing the control switch.
