Littelfuse TDUB Delay On Break Timer

Off Delay Littelfuse Series TDUB Timer from Flow Factor 

The Littelfuse TDUB Series combines digital timing circuitry with universal voltage operation. Voltages of 24 to 240VAC and 12 to 24VDC are available in three ranges. The Littelfuse TDUB Series offers DIP switch selectable time delays ranging from 0.1 seconds to 102.3 minutes in three ranges. Its 1A rated output, ability to operate on multiple voltages, and wide range of switch selectable time delays make the TDUB Series an excellent choice for process control systems and OEM equipment.

Littelfuse TDR TDUB Timer

Operation (Delay-on-Break)
Input voltage must be applied before and during timing. Upon closure of the initiate switch, the output energizes. The time delay begins when the initiate switch is opened (trailing edge triggered). The output remains energized during timing. At the end of the time delay, the output de-energizes. The output will energize if the initiate switch is closed when input voltage is applied.
Reset: Reclosing the initiate switch during timing resets the time delay. Loss of input voltage resets the time delay and output.

Features     &       Benefits 

Dip Switch Timing Adjustment  >>  Provides setting accuracy of +/-2% 

User selectable time delay  >>  Timing settings are switch selectable 0.1s - 102.3m in three ranges for added flexibility 

1A steady, 10A inrush solid-state output  >>  Provides 100 million operations in typical conditions. 

Totally solid state and encapsulated >> No moving parts to arc and wear out over time and encapsulated to protect against shock, vibration, and humidity

SSAC Timers-Voltage Monitors

SSAC timers and voltage Monitors:

These are three of SSAC's more common items:

The SSAC TRDU Series is a versatile universal time delay relay with 21 selectable single and dual functions. The dual functions replace up to three timers required to accomplish the same function. Both the function and the timing range are selectable with switches located on the face of the unit. Two LED's indicate input voltage and output status. This device offers full 10 A isolated relay output contacts in either SPDT or DPDT. The TRDU replaces hundreds of part numbers, thereby, reducing your stock inventory requirements.

The SSAC PLM Series continuously measures the voltage of each of the three phases. It separately senses Undervoltage, Voltage Unbalance (including Phase Loss), and Phase Reversal. Protection is assured during periods of large average voltage fluctuations, or when regenerated voltages are present. Both Delta and Wye systems can be monitored; no connection to neutral is required. 380 V AC and 480 V AC units are encapsulated.

Operation

The output relay is energized and the LED glows when all voltages are acceptable and the phase sequence is correct. Under and unbalanced voltages (including phase loss) must be sensed for a continuous trip delay period before the relay and the LED are de-energized. Re-energization is automatic upon correction of the fault condition. The output relay will not energize if a fault condition is sensed as power is applied.

The SSAC TDR Series of time delay relays are comprised of digital circuitry and a separate oscillator to provide high accuracy and stability. The ON and OFF delays are selected by means of ten binary switches, which allow the setting of the desired delay the first time and every time. Full 10 A isolated DPDT output contacts.

Operation

Upon application of input voltage, the output relay is energized and the ON time begins. At the end of the ON time, the output de-energizes and the OFF time begins. At the end of the OFF time, the output relay is energized and the cycle repeats as long as input voltage is applied. The OFF time may be the first delay in recycling timers. Reset: Removing input voltage resets the output and time delays, and returns the sequence to the first delay.
