Why Choose the ABB CT-ARS.11P True OFF-Delay Timer?

The ABB CT-ARS.11P is a reliable electronic true 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 true OFF-delay function without requiring an auxiliary voltage, with a single changeover relay output for flexible control applications.

The CT-ARS.11P provides 10 selectable time ranges from 0.05 s to 300 h, allowing accurate timing control across a wide range of industrial applications. The timer operates from a wide 24–240 V AC/DC control supply and provides a 1 c/o (SPDT) relay output rated at 250 V / 4 A.

Featuring Easy Connect push-in terminals, front-face adjustment and a compact 22.5 mm DIN-rail housing, the CT-ARS.11P is designed for straightforward installation within industrial control cabinets. Its true OFF-delay operation allows the output to remain energised for the selected time after the control voltage is removed.

Key Advantages

  • Reliable true OFF-delay timer relay for industrial automation.
  • True delay-on-break operation without auxiliary voltage.
  • 10 selectable time ranges from 0.05 s to 300 h.
  • Wide 24–240 V AC/DC control supply.
  • 1 c/o (SPDT) relay contact for flexible switching.
  • Maintenance-free Easy Connect push-in terminals simplify installation.
  • Compact 22.5 mm wide DIN-rail housing for control cabinets.

Reliable True OFF-Delay Control for Industrial Automation

True OFF-delay timer relays such as the ABB CT-ARS.11P provide controlled switching after the control voltage is removed. This makes the timer particularly useful where equipment, motors, fans, lighting circuits or other loads need to remain energised for a defined period before switching off.

The CT-ARS.11P combines true OFF-delay operation with ten selectable time ranges and a wide 24–240 V AC/DC control supply. Its single changeover relay output provides flexible switching within automation and control circuits, while the compact DIN-rail housing and push-in terminals support efficient panel installation.

Typical Applications

  • Industrial automation and control panels.
  • Delayed shutdown and run-on circuits.
  • Motor and actuator control systems.
  • Fan and ventilation run-on applications.
  • Machine control and production equipment.
  • Lighting and electrical control systems.
  • Sequencing and interlocking applications.
  • OEM machinery and industrial automation equipment.
