Allen-Bradley RTC40S010U1 RTC Timing Relay Module

The Allen-Bradley 700-RTC40S010U1 is a fixed-time, solid-state timing relay (RTC) from the 700-series RTC family, designed for industrial automation where a precise, non-adjustable delay is required between energizing a control input and the corresponding output. It is a compact, plug‑in timing module intended to replace external timers in control panels, offering straightforward integration and reliable operation in industrial environments. The unit accepts a power input of 110–120 VAC at 50/60 Hz or 120 VDC, enabling use with common industrial power supplies, and provides timing outputs dedicated to the relay’s on-delay function. With no user-adjustable potentiometer, the timing interval is factory-set for this model (RTC40S010U1), making it suitable for simple on-delay sequencing, interlocks, and timed-control tasks in machines and panels. This configuration helps reduce wiring complexity and timing drift associated with discrete timers, while remaining compatible with standard Allen-Bradley automation equipment and service practices.
