1SVR730010R0200

The ABB 1SVR730010R0200 (CT-MFS.21S) is a high-performance multifunction electronic timer relay designed for industrial automation, electrical control panels, motor control systems, and advanced timing applications. Manufactured by ABB, this timer belongs to the CT-S series and offers 10 selectable timing functions with 10 adjustable time ranges covering 0.05 seconds to 300 hours. It operates with a wide rated control supply voltage of 24–240V AC/DC and features two changeover (SPDT) output contacts rated at 250V and 4A. Its versatile timing capabilities make it suitable for industrial applications requiring accurate and flexible time-controlled switching.

The ABB CT-MFS.21S multifunction timer relay supports various timing operations, including ON-delay, OFF-delay, impulse functions, flashing operations, pulse generation, and star-delta timing. It features two volt-free control inputs and supports the connection of a remote potentiometer for fine adjustment of the time delay. The second changeover output contact can also be configured as an instantaneous contact, providing additional flexibility for industrial control circuits.
