ATC Series 407 Multifunction Timer 407A500F3X 24-240VAC

The ATC Series 407 Multifunction Timer is a versatile, plug-in timing relay designed for industrial automation and control applications. Manufactured by Automatic Timing & Controls (ATC), this model 407A500F3X operates on a universal voltage range of 24-240 VAC at 50/60 Hz, making it suitable for a wide array of electrical systems without the need for separate power supplies. It features three selectable modes: On Delay, Interval, and Off Delay, allowing precise control over timing sequences in processes such as machinery startup, conveyor systems, pump controls, and lighting automation. The analog dial provides adjustable timing settings, with the '500' code indicating a range up to 500 units (typically seconds or minutes, depending on configuration). Key benefits include its compact, durable design for easy integration into control panels, high reliability in harsh environments, and multifunction capability that reduces the need for multiple devices. Compared to similar products like Omron or Eagle Signal timers, the ATC 407 offers superior mode flexibility and a broader voltage tolerance, though it may lack digital precision found in modern programmable models. Drawbacks include analog adjustment which can be less precise than digital interfaces and potential obsolescence in highly automated setups. This unit appears used but in good condition, with no visible damage, making it ideal for cost-effective replacements in legacy systems. Applications span manufacturing, HVAC, and process control industries.
