SSAC MSM445W9 Solid State Time Delay Relay AC

SSAC MSM445W9 is a compact solid-state time-delay relay designed for 120 VAC control circuits, delivering a fixed 45-second delay from power application to output activation and rated to switch up to 0.5 A of load current. As a solid-state timer, it has no moving parts, offering quiet operation and a longer potential life than electro-mechanical timers. The MSM445W9 is intended for simple timing control in 120 VAC systems where a defined 45-second delay is required to sequence downstream devices or control logic. Key specifications associated with this model include an input voltage of 120 VAC, an output current rating of 0.5 A, and the characteristic 45-second delay implied by the model designation. This timer is part of SSAC's family of solid-state timing controls, which are designed to provide reliable on-delay timing with minimal wear in industrial and OEM applications.
