ABB – CT-MFS (1SVR430010R0200) – Multifunction Timer, 2 SPDT, 24–240V AC/DC

The ABB CT-MFS (1SVR430010R0200) is a multifunction electronic timer relay featuring 2 changeover (SPDT) contacts and a wide supply voltage range of 24–240V AC/DC, making it suitable for global applications. This device offers 10 selectable timing functions (including ON-delay, OFF-delay, impulse-ON, impulse-OFF, flasher, star-delta changeover, and more) and 10 time ranges from 0.05 seconds up to 300 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 (22.5 mm width) and designed for robust industrial environments.
