When supply voltage is applied, the OFF delay (T1) begins. Upon completion of the OFF delay, the load energizes and the ON delay (T2) begins. Upon completion of the ON delay, the load de-energizes and one cycle is complete. This ON/OFF cycling continues until the supply voltage is removed. The OFF delay always equals the ON delay.

When supply voltage is applied to the input terminals, the relay energizes and the time delay begins. Upon completion of the delay period, the relay de-energizes. Reset during or after the delay period is accomplished by removal of the supply voltage

The time delay begins when supply voltage is applied to the input. Upon completion of the delay period, the relay energizes. Reset during or after the delay period is accomplished by removal of the supply voltage. The TBC Series will not false transfer if supply voltage is removed prior to completion of the delay period. A fast recycle time permits accurate, high speed, continuous operation.

Supply voltage is continuously applied to the input. An external isolated switch between pins 5 and 6 controls the timer. When closed, the relay energizes. Opening the switch initiates the delay period. Upon completion of the delay period, the relay de-energizes. If the control switch recloses during the delay period, the relay remains energized and the timer resets to zero.
NOTE: The TBD Series is available in an 8-pin SPDT and an 11-pin DPDT configuration.

The TBU Series offers the accuracy of DIP SWITCH delay ranges “A” through “E” as well as the user programmable model, DIP SWITCH delay range “P,” with 4 different ranges obtainable by either leaving 2 designated terminals unconnected or by connecting them to the appropriate terminals as shown below. The 6 most common modes of operation are easily selected by the use of one or more jumpers applied externally between designated base pins as outlined below. These features, coupled with 6 most popular supply voltages, make this timer one of the most versatile and cost effective Time Delay Relays available today. The CMOS digital circuitry provides high accuracy, repeatability and fast reset times.

Upon completion of the OFF time, the relay energizes and the ON time begins. Upon completion of the ON time, the relay de-energizes and the cycle is complete.

Voltage is continuously applied to the input. An external isolated switch controls the timer. When closed, the ON delay (T1) begins. Upon completion, the relay energizes. When the switch opens, the OFF delay (T2) begins. Upon completion, the relay de-energizes and the cycle is complete. Reset is accomplished by reclosing the control switch after the timing cycle has completed. If the switch opens during the ON delay mode, the relay will remain de-energized and (T1) will reset. If the switch is reclosed during the OFF delay mode, the relay will remain energized and (T2) will reset. Both delay periods are independently adjustable.

When power is applied to the input, the OFF time begins. Upon completion of the OFF time, the relay energizes and the ON time begins. Upon completion of the ON time, the relay de-energizes and one cycle is complete. This OFF/ON cycling continues until the voltage is removed from the input.

The OFF time always equals the ON time.

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.

When voltage is applied to the input, the internal relay energizes and the ON time (T1) begins. Upon completion of the ON time, the relay de-energizes and the OFF time (T2) begins. At the completion of the OFF time, one ON/OFF cycle is completed. This cycling action continues until voltage is removed from the input. The ON/OFF ratio is adjustable from 0 to 100 percent of time base. 0% is OFF; 100% is ON. Reset is accomplished by interrupting the input voltage.

When voltage is applied to the input terminals, the relay energizes. When voltage is removed, the OFF delay begins. Upon completion of the delay period, the relay de-energizes. Reset is accomplished by reapplying voltage to the input terminals.
NOTE: If voltage is reapplied during the delay period, the relay remains picked up and the timer resets to zero. Voltage must be applied for a minimum of .5 seconds to assure proper operation.

The TDU Series is one of the most versatile single timers available today. One model replaces forty-eight industry standard devices; 4 wide delay ranges x 6 most common modes of operation x 2 supply voltages—since they will operate on both AC and DC. The CMOS digital circuitry provides high accuracy, repeatability and fast reset times. The heavy duty relays are rated for continuous operation at 10 amps. All programming is easily accomplished externally by using one or more jumpers between designated base pins—no trap doors to open, no switches to set, no disassembly required.

The 657 family consist of two (2) models with four (4) operating modes that can be selected by the user. The Model 657-8-1000 has an input power of 12VDC for dry contact type inputs and the Model 657-8-2000 employs an input power of 108-240 VAC/DC. Other than input power, all characteristics of both models are similar. When programmed for ON-Delay or Interval modes, the input switch functions as a time inhibit input if closed during timing or as a reset input if closed after the timing cycle is complete.
