Why Choose the ABB CT-APS.22S OFF-Delay Timer Relay?
The ABB CT-APS.22S is a compact and reliable electronic timer relay designed to provide precise OFF-delay timing in industrial control, automation and electrical systems. As part of the ABB CT-S timer relay range, it provides a single OFF-delay function with two 1 C/O (SPDT) changeover outputs and flexible timing adjustment.
The CT-APS.22S provides true OFF-delay operation with 10 selectable time ranges from 0.05 s to 300 h. Its voltage-related control input, front-face adjustment controls and status indication make it suitable for applications where controlled delay after removal of the control signal is required.
With a rated control supply voltage of 24–48 V DC / 24–240 V AC and 2 C/O (SPDT) output contacts rated at 250 V / 4 A, the CT-APS.22S provides flexible switching and timing control in industrial automation and control panels. Its compact 22.5 mm housing is designed for straightforward DIN-rail mounting.

Reliable Timing Control for Industrial Automation
Timer relays such as the ABB CT-APS.22S provide controlled switching delays within electrical control and automation systems. An OFF-delay function keeps the output in its operating state for the selected period after the control signal is removed, helping equipment and processes complete defined sequences consistently.
The CT-APS.22S combines flexible timing adjustment with a compact DIN-rail format and screw terminal connections. Its broad control supply voltage range and selectable timing periods allow the relay to be integrated into a wide variety of industrial control panels and automation applications.
Typical Applications
- Industrial automation and control panels.
- Machine control and sequencing systems.
- Motor control circuits requiring delayed switch-off.
- Conveyor and material handling equipment.
- Ventilation and fan control systems.
- Industrial machinery and production equipment.
- Electrical control systems requiring adjustable OFF-delay timing.
