ASCO 214B281 345183 A Sequential Controller

ASCO 214B281 345183 A Sequential Controller is a compact control board that sequences ASCO pilot valves used in industrial dust collection and other automated processes. This CSA and UL‑approved controller is designed for installation in Types 3, 4X and 12 enclosures, with enclosure kits 125483-1 (closed) and 125483-2 (window) specified for different mounting conditions. It delivers timed, repeatable action with ±5% repetitive accuracy on time sequences, enabling precise pulsing of valves in multi‑valve cycles. The unit is specified to operate in -10 °F to 130 °F (-23 °C to 54 °C) when mounted in closed enclosures, and to store in -20 °F to 150 °F (-29 °C to 66 °C) for windowed enclosures. Model identification includes revision 345183 A. In practice, ASCO Sequential Controllers like the 214B281 coordinate the sequence of valve actuation in dust collectors and similar equipment, ensuring synchronized operation of multiple pilot valves and associated control components for repeatable cycle operation. Typical applications include dust collection, material handling, and other industrial processes where timed valve sequencing is required to achieve consistent, automated cycles.
