ABB CT-MXS Multifunction Timer Relay, 24-48 V DC / 24-240 V AC, 2 C/O, 10 Functions, DIN Rail 1SVR730030R3300

In industrial automation, timing control is critical for sequencing operations, delaying starts, or pulsing outputs. The ABB CT-MXS multifunction timer relay provides precise and flexible timing in a compact DIN rail module. With ten selectable functions and a wide time range from 0.05 seconds to 300 hours, it adapts to diverse control requirements. The dual supply voltage (24-48 V DC / 24-240 V AC) and two changeover contacts rated at 4 A make it suitable for many applications.

Who is it for
