Allen-Bradley 700-NT200A1 Timing Control Relay

Allen-Bradley 700-NT200A1 is an industrial control relay that pairs a pneumatic timing attachment with a 700-N style base to provide a timed ON delay in relay circuits. It features two normally open contacts (2 N.O.) and a coil rated for 110 V AC at 50 Hz or 120 V AC at 60 Hz, accommodating common North American power standards. The timing unit is mounted on a 700-N relay base, enabling compact, integrated timing for sequencing and interlock functions in automation systems. This configuration is designed for timing-controlled actuation in industrial control schemes, where precise delay before energizing a load is required. The timing attachment leverages pneumatic actuation to set the delay, while the two NO contacts handle switching tasks in the controlled circuit. In practice, this assembly is used in control circuits to sequence actuators, valves, or other loads by introducing a deliberate on-delay, reducing the need for separate timer modules and simplifying panel wiring.
