TUTTNAUER 90241MRT Sussman Board AUX LWCO With 30 Sec Delay – 9074

The Tuttnauer 9074 is an auxiliary low-water-cutoff (LWCO) board assembly for the Tuttnauer 90241MRT autoclave. It monitors water level in the sterilizer's chamber and interrupts the cycle if the water drops below a safe threshold, with a 30-second delay before shutdown. This board is a safety-critical component in the sterilization circuit and is typically replaced when the LWCO sensor fails to respond or the board loses continuity to the chamber probe.
