FAQ

How do I set the time delay on the RE7TL11BU?

The time delay is configured using the rotary selectors on the front of the relay. One dial selects the time base (e.g., seconds, minutes, hours) and the other adjusts the multiplier within that range to achieve the precise delay required.

Is this relay compatible with both AC and DC control circuits?

Yes, the RE7TL11BU is highly versatile. It features a wide-range input that accepts both AC and DC voltages from 24V to 240V, making it suitable for a vast array of industrial control applications without needing different models for different voltage types.

What does the “On-Delay” function mean for this timer relay?

The “On-Delay” function, also known as “power-on delay”, means that the timing period begins when the control voltage is applied. After the preset time has elapsed, the output contacts change state and remain in that state until the control voltage is removed.
