Reliable OFF-Delay Control for Industrial Automation
OFF-delay timer relays such as the ABB CT-AHS.22P provide controlled switching for a defined period after the control signal is removed. This makes them useful for sequencing, delayed shutdown, ventilation, motor control and other applications where equipment must remain active for a set time before switching off.
The CT-AHS.22P combines a dedicated OFF-delay function with ten selectable time ranges, allowing the same timer relay to accommodate applications ranging from short switching delays through to extended timing periods. Its two changeover relay outputs provide flexible switching, while the volt-free control input and compact DIN-rail design support straightforward integration into industrial control systems.
Typical Applications
- Industrial automation and control panels.
- Delayed shutdown and sequencing circuits.
- Motor and actuator control systems.
- Machine control and production equipment.
- Ventilation and fan run-on applications.
- Lighting and electrical control systems.
- OEM machinery and industrial automation equipment.
