When you need reliable power-off logic, the Wengart Delay Time Relay TBT7 provides the industrial-grade performance you demand. This Single function Time Delay Relay is engineered for "Delay OFF" scenarios: once the control signal (S terminal) is deactivated, the relay stays energized for your pre-set duration before cutting power. It's the essential component for ensuring ventilation fans clear the air or machines cool down properly after use.
One Relay for Every System
Forget worrying about matching voltages. Our **Universal Voltage** design supports ACDC 12V-240V, making it a "Swiss Army Knife" for electricians and hobbyists. The 16A 1SPDT output is powerful enough to handle a wide range of Load Control tasks, while the Rail Mounting design ensures it fits perfectly into any standard breaker box or industrial control panel.
Function: Delay OFF (Signal Triggered)
Supply Voltage: ACDC 12-240V (50/60Hz)
Output: 1 x SPDT (Changeover)
Current Rating: 16A / 250VAC (Resistive)
Time Range: 0.1s - 10 days (adjustable)
Indication: Power (Green LED), Output (Red LED)
Installation: Standard 35mm DIN Rail
Q: Is this a "Delay ON" or "Delay OFF" relay?
A: This is a Delay OFF relay. It requires a trigger signal (via terminal S). When the signal is disconnected, the timer starts, and the relay remains active until the time expires.
Q: Does it work with my 24V Solar system and 120V AC household fan?
A: Yes! The **Universal Voltage** input handles both DC and AC from 12V up to 240V. Just ensure your load does not exceed the 16A limit.
Q: What does the S terminal do?
A: The S terminal is the trigger. You connect your switch or sensor here. Once that switch is turned off, the TBT7 begins counting down the delay you set on the dial.
