Marsh Bellofram Diversified Electronics Division TBG Series Repeat Cycle-ON Timer First DIP Switch TDR

Product catalog summary

Overview: The TBG Series is a time delay relay system designed for repeat cycle operations, where the relay alternates between ON and OFF states. The cycle continues until the supply voltage is removed.

DIP Switch Operation: Time delay is digitally selected using ten binary switches. Each switch represents a time increment, and the sum of switches in the ON position determines the delay, eliminating trial-and-error adjustments.

Specifications:

Time Delay Range: Five ranges from 0.1 seconds to 1,023 minutes.
Output Rating: 10 A at 250 VAC or 24 VDC, resistive.
Accuracy: Setting accuracy is ±2% or ±50 mSEC; repeat accuracy is ±0.1% or ±8.3 mSEC.
Reset Times: 100 mSEC before timeout, 50 mSEC after timeout.
Supply Voltage: Options include 12, 24, 48, 120, or 240 VAC, 50/60 Hz, or DC with ±10% tolerance.
False Transfer: No false transfer.
Reverse Polarity Protection: Yes.
Power Required: Approximately 3 VA.
Duty Cycle: Continuous.
Temperature Rating: Operating range is 32° to 131°F (0° to +55°C); storage range is -49° to 185°F (-45° to +85°C).
Life Expectancy: Mechanical life is 10 million operations minimum; electrical life is 100,000 operations at rated load.
Indicators: An LED glows when the relay is energized.
Isolation: 1,500 volts between input and output.
Weight: 0.4 lbs.

Model Number: The model number is determined by control voltage and time delay range, with options for various voltages and delay increments.

800.727.5646 atcdiversified.com Diversified Electronics TBG Series Time Delay Relays // TBG Series 65 Repeat Cyc le–ON T ime F i r s t D I P Sw i t c h T DR When supply voltage is applied to the input, the relay energizes and ON time (T1) begins. Upon completion of the ON time, the relay de-energizes and the OFF time (T2) begins. Upon completion of the OFF time, the relay energizes and one cycle is complete. This ON/OFF cycling continues until supply voltage is removed from the input. The ON/OFF delay periods are independently selectable within the same range. DIP SWITCH OPERATION Digital selection of the time delay is accomplished by the use of ten (10) binary switches, each marked with a time increment. The time periods, of which there are five (5) ranges, represented by each switch in the ON position is added together to obtain the desired time delay. No more trial-by-error adjustments.
