Why Choose the ABB CT-APS.12P OFF-Delay Timer?
The ABB CT-APS.12P 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 an OFF-delay function with a single changeover relay output for flexible control applications.
The CT-APS.12P 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 rated control supply of 24–48 V DC / 24–240 V AC and provides a 1 c/o (SPDT) relay contact rated at 250 V / 4 A. Its voltage-related, non-floating control input provides the trigger for the timing function.
Featuring Easy Connect push-in terminals, front-face adjustment and a compact 22.5 mm DIN-rail housing, the CT-APS.12P is designed for straightforward installation within industrial control cabinets. Its OFF-delay operation keeps the relay output energised for the selected time after the control signal is removed.
