Frequently Asked Questions
What does OFF-delay mean for the CT-AHD.22?
In OFF-delay mode, the output contacts remain energised for a set time period after the control input signal is removed. This allows controlled, time-based shutdown sequences in automation systems.
What supply voltages does the CT-AHD.22 accept?
The CT-AHD.22 accepts 24–48V DC and 24–240V AC, providing broad compatibility with most industrial control power supplies without requiring separate variants for AC and DC systems.
How wide is the CT-AHD.22 for DIN rail mounting?
The CT-AHD.22 has a width of 17.5 mm, fitting neatly onto standard DIN rails alongside other modular devices in compact control enclosures.
