An off delay timer contact ______.

• A. energizes when the timer is activated and deenergizes when the timer times out
• B. energizes immediately
• C. deenergizes when the input goes high
• D. remains closed while power is applied

Answer: (A)

An off-delay timer keeps the output energized for a set period after the timer is activated, then it opens. The contact closes immediately when the timer receives a signal (energized at activation) and remains closed for the preset interval, but once that interval times out, the contact opens (deenergizes). This behavior explains why the correct statement is that it energizes on activation and deenergizes when the timer times out. It’s used to hold a load on for a short time after a condition occurs, and then release it after the delay.
