Marsh Bellofram Diversified Electronics Division TDD/TUD Series OFF-Delay Relay Output

Product catalog summary

Overview: The TDD/TUD Series from Diversified Electronics features time delay relays designed for off-delay relay output. These devices are used to control the timing of electrical circuits, with voltage continuously applied to the input and an external switch controlling the timer.

Specifications:

Timing Ranges: Virtually unlimited, with standard ranges available on page 84.
Output Rating: DPDT 10 A @ 250 VAC or 24 VDC, SPDT 10 A @ 120 VAC.
Timing Tolerances: Minimum setting +0–20%, Maximum setting ±10%.
Repeatability: 1% maximum, no first cycle effect.
Reset Times: 100 mSEC before timeout, 50 mSEC after timeout.
Recycle Time: 40 mSEC.
Supply Voltage: 24 or 120 VAC or VDC, 50/60 Hz, ±10%.
False Transfer: No.
Reverse Polarity Protected: Yes.
Power Consumption: Approximately 3 watts.
Duty Cycle: Continuous.
Temperature Rating: Operate 32° to 131°F, Storage -49° to 185°F.
Life Expectancy: Mechanical 10 million operations, Electrical 100,000 operations at rated load.
Weight: 6 oz.

Model Number Configuration: The model number includes series, relay output, supply voltage, type of operation, enclosure style, and delay period. Example: TDD-120-AKA-600 indicates a delay on release, 120 Volts AC or DC, knob adjustable from 6 to 600 seconds, 11-pin octal plug-in UL Recognized.

Operation: The relay energizes when the control switch is closed and de-energizes after the delay period when the switch is opened. If the switch recloses during the delay, the relay remains energized and the timer resets.

An external isolated switch 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.
