Why Choose the ABB CT-AHS.22P OFF-Delay Timer?
The ABB CT-AHS.22P is a reliable electronic OFF-delay timer relay designed for precise time-delayed switching in industrial automation, control panels and electrical control systems. As part of the proven ABB CT-S timer range, it provides a dedicated OFF-delay function with selectable timing ranges and two changeover relay contacts for flexible control applications.
The CT-AHS.22P provides 10 selectable time ranges from 0.05 s to 300 h, allowing accurate timing control across a wide variety of industrial applications. Its volt-free control input provides flexible triggering, while the Easy Connect push-in terminals enable straightforward tool-free electrical installation.
With a rated control supply voltage of 24–240 V AC / 24–48 V DC and 2 c/o (SPDT) relay contacts, the CT-AHS.22P is suitable for machinery, automation and electrical control circuits where an OFF-delay is required after the control signal is removed. Its compact 22.5 mm housing is designed for DIN-rail mounting within control cabinets.

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.
