ABB CT-MFE time relay, part number 1SVR550029R8100, is a multifunction electronic timer relay from ABB (the successor to ASEA BROWN BOVERI’s 1SVR line). It accepts 24–240 V AC/DC and provides six timing functions via a front‑panel rotary selector, with a timing range of 0.05 s to 100 h. The unit features a single changeover (SPDT) output contact rated up to 250 VAC and 4 A. This makes it suitable for automation control panels where timed switching, delays, or impulse sequences are required to drive loads or signaling circuits.
