Why Choose the ABB CT-APS.12S OFF-Delay Timer Relay?
The ABB CT-APS.12S 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 a 1 C/O (SPDT) output and flexible timing adjustment.
The CT-APS.12S 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 a 1 C/O (SPDT) output rated at 250 V / 4 A, the CT-APS.12S 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.12S 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 safely and consistently.
The CT-APS.12S 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.
