Why Choose the ABB CT-ARC.12 Time Relay?
The ABB CT-ARC.12 is a compact and reliable dual-function electronic time relay designed for precise timing and sequencing in industrial control and automation systems. As part of the established ABB CT-C timer relay range, it provides OFF-delay and impulse-OFF functions without requiring an auxiliary supply, making it suitable for a wide range of control panel and machinery applications.
This timer relay provides four selectable time ranges from 0.05 s to 10 min, allowing the required delay or impulse period to be configured for different control applications. Its compact housing and front-mounted adjustment controls simplify installation, commissioning and operation in industrial control systems.
With a rated control supply voltage of 24–48 V DC or 24–240 V AC and one changeover relay output, the CT-ARC.12 provides flexible switching capability without the need for an auxiliary voltage supply. Its compact 17.5 mm wide housing is well suited to installations where control panel space is limited.

Reliable Timing for Industrial Automation
Time relays such as the ABB CT-ARC.12 provide controlled timing functions within electrical automation systems. Its OFF-delay function maintains the relay output for a defined period after the control signal is removed, while the impulse-OFF function provides a timed output pulse following the appropriate control sequence.
The CT-C range is designed for practical industrial control applications where accurate and repeatable timing is required. The CT-ARC.12 combines two useful timing functions, selectable time ranges and a compact DIN rail-mounted housing, providing flexible integration into control cabinets and electrical automation systems without requiring an auxiliary supply.
Typical Applications
- Industrial automation and control panels.
- Motor and contactor sequencing systems.
- Machine control and production equipment.
- Delayed switching of valves and actuators.
- Lighting and signalling control systems.
- Process control and electrical sequencing applications.
