Marsh Bellofram Diversified Electronics Division TDP Series Percentage Timer Relay Output

Product catalog summary

Overview: The TDP Series Time Delay Relays by Diversified Electronics are designed to control the timing of electrical circuits. When voltage is applied, the relay energizes, initiating the ON time (T1). After T1, the relay de-energizes, starting the OFF time (T2). This cycle repeats until the input voltage is removed. The ON/OFF ratio is adjustable from 0% (OFF) to 100% (ON).

Specifications:

Output Rating: DPDT, 10 A at 250 VAC or 24 VDC, resistive; 211 VA at 120 VAC, inductive.
Time Base Tolerances: ±10%.
Repeatability: 0.5% typical.
Adjustability: 0 to 100% of time base.
Supply Voltage: 24 or 120 VAC or VDC, 50/60 Hz; ±10%.
False Transfer: No.
Reverse Polarity Protected: Yes.
Power Consumption: 2 watts.
Temperature Rating: Operate 32° to 131°F (0° to +55°C); Storage -49° to 185°F (-45° to +85°C).
Life Expectancy: Mechanical 10 million operations (minimum); Electrical 100,000 operations at rated load.
Weight: 5.6 oz.

Operation: The relay's operation is based on the application of voltage to the input, which triggers the timing cycle. The cycle is adjustable and can be reset by interrupting the input voltage.

Model Variants: The TDP Series offers various models with different supply voltages (24 VAC/DC, 110/120 VAC/DC), operation types (knob adjustable, lock nut adjustable), enclosure styles (8-pin octal plug-in, blade plug-in), and time bases (ranging from 60 seconds to 60 minutes).

TDP Series Diversified Electronics atcdiversified.com 800.727.5646 80Time Delay Relays // TDP Series 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. P e r c e n t a g e Tim e r R e l a y Ou tput SUPPLY VOLTAGE TIME BASE OUTPUT 25% T1 T2 TIME BASE 75% Example shows 25% setting.
