Wengart Delay Off Time Relay TBT7-C1, Single Function Timer ACDC 12V-240V, 16A 1SPDT Output with Signal Trigger, DIN Rail Mount for Bathroom Fan & Motor Control, Industrial Universal Voltage

Precision Timing Control for Modern AutomationWhen 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.Technical SpecificationsFunction: 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 RailFrequently Asked Questions (Preventing Setup Errors)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.

• Dedicated Delay OFF Logic: Specifically designed for applications requiring power to remain on after a trigger signal is removed. This Single function Time Delay Relay is the perfect solution for bathroom exhaust fans, corridor lighting, or industrial cooling fans where a "run-on" time is essential for air quality or heat dissipation.
• Universal Voltage Compatibility: Simplify your inventory and installation. Our ACDC12-240V wide-range input makes this relay compatible with almost any power system—from 12V/24V RV and solar setups to 120V/240V residential and industrial circuits. One unit handles it all without the need for additional transformers.
• Heavy-Duty 16A Switching: Built for reliability under load. Featuring a robust 1SPDT (1 Form C) output, this relay safely manages a 16A resistive load. It provides crisp, decisive switching for Delay Control of Load, ensuring your motors and lighting systems operate smoothly without contact welding or failure.
• Ultra-Wide Timing Range: Precision control at your fingertips. The intuitive rotary dials allow you to set the delay from 0.1 seconds to 10 days. Whether you need a brief buffer for a machine or a multi-day cycle for an automated process, the TBT7 offers the versatility required for complex automation projects.
• Space-Saving Rail Mounting: Designed for professional control cabinets. The compact modular housing features a standard 35mm DIN Rail Mounting clip and a clear Output Indication LED. The status light provides instant visual feedback, making troubleshooting and system testing faster and more intuitive for DIYers and pros alike.
