Why Choose the ABB 1SVR500110R0000 CT-AHD.12 Time Relay?
The ABB 1SVR500110R0000 is a compact and reliable electronic time relay designed for precise timing control in industrial automation, electrical control panels and machine control applications. As part of the trusted ABB CT-D timer relay series, it provides an OFF-delay timing function with flexible adjustment ranges and dependable switching performance for professional control systems.
This timer relay provides an OFF-delay (delay on break) function, keeping the output energised for the selected delay period after the control signal is removed. Its narrow 17.5 mm DIN rail mounting design makes it suitable for compact control cabinets where space efficiency and reliable timing control are required.
With selectable time ranges from 0.05 s to 100 h, a universal 24–240 V AC and 24–48 V DC supply range, and a 1 changeover (SPDT) output contact rated at 250 V / 6 A, the ABB 1SVR500110R0000 is ideal for industrial automation, process control and electrical sequencing applications.
