ABB 1SVR500110R0100 CT-AHD.22 electronic off-delay timer relay with 0.05 s to 100 h timing range and 24–240 V AC / 24–48 V DC supply for industrial automation control.
£81.91
The ABB 1SVR500110R0100 is a compact and reliable electronic timer relay designed for precise time delay control in industrial automation, control panels and electrical distribution systems. As part of the ABB CT-D timer relay series, the CT-AHD.22 provides an adjustable off-delay function for applications requiring controlled switching after removal of the control signal.
This timer relay combines flexible timing adjustment, compact DIN rail mounting and reliable relay outputs to simplify automation control tasks. Its wide supply voltage range allows integration into various AC and DC control systems, while LED status indicators provide clear visibility of operating conditions.
With a time range from 0.05 s to 100 h, a 24–240 V AC / 24–48 V DC control supply and 2 changeover relay contacts, the ABB CT-AHD.22 is suitable for industrial sequencing, motor control, lighting systems and general automation applications.
Electronic timer relays such as the ABB CT-AHD.22 provide accurate time-based switching control for automation systems. The off-delay function allows connected equipment to continue operating for a defined period after the control signal is removed, improving process control and system flexibility.
The ABB CT-D series is designed for industrial control engineers and panel builders requiring compact, dependable timing solutions. Its narrow modular housing and DIN rail mounting make it suitable for space-efficient electrical installations.
