The ABB CT-MFS (SVRR) is a multifunction electronic timer relay featuring changeover (SPDT) contacts and a wide supply voltage range of –V AC/DC, making it suitable for global applications. This device offers selectable timing functions (including ON-delay, OFF-delay, impulse-ON, impulse-OFF, flasher, star-delta changeover, and more) and time ranges from . seconds up to hours, providing exceptional flexibility for automation and control tasks.

The timer relay is equipped with a rotary switch for function selection and a potentiometer for fine time adjustment, plus a sliding switch to set the second SPDT contact as instantaneous. It features status LEDs for supply voltage and output relays, and supports remote potentiometer connection for external time adjustment. The unit is DIN rail mountable (. mm width) and designed for robust industrial environments.
