1SVR508110R0100

The ABB 1SVR508110R0100 (CT-AHC.22) is a high-quality, single-function electronic OFF-delay timer relay designed for industrial automation, electrical control panels, machinery control systems, and time-dependent switching applications. Manufactured by ABB, this timer belongs to the CT-C series and provides a reliable OFF-delay (delay-on-break) function with seven adjustable timing ranges covering 0.05 seconds to 100 hours. It operates with a rated control supply voltage of 24–240V AC or 24–48V DC and features two changeover (SPDT) output contacts rated at 250V and 4A. Its compact construction makes it suitable for industrial installations requiring dependable time-controlled switching.The ABB CT-AHC.22 OFF-delay timer relay is designed for applications requiring electrical equipment to remain activated for a predetermined period after a control signal is removed. It uses a voltage-related control input and requires the auxiliary supply to remain connected during the timing operation.
