Industrial ARPT-200 Timer

Westinghouse 90521 ARPT-200 timer is a panel-mounted relay timer designed for industrial automation and electrical control systems, delivering adjustable timing and delayed control in a 10–200 second range. Commonly installed in automation panels and MCC systems, this timer supports manufacturing systems, conveyor controls, pump systems, and motor starter circuits that require precise sequence timing and delayed operation. The ARPT-200's primary function is adjustable timing and delayed control, with a timing range of 10 to 200 seconds, making it suitable for process control and sequence timing in industrial equipment. It is used by maintenance teams, OEMs, and system integrators for control system repairs, automation retrofits, replacement projects, and equipment maintenance. Typical installations include automation panels, MCCs, and cabinets, where delayed timing and relay control functions are required. Common replacements include Allen-Bradley 700-FSM4UU23, Omron H3CR-A8 Timer Relay, and Schneider Electric RE17RMMW.
