Allen-Bradley · HMIs & Displays

Description  The Allen-Bradley 700-NT is a pneumatic timing unit designed for use with Bulletin 700-N industrial relays. It features a standard ON-delay timing configuration with timed contacts and is easily convertible to OFF-delay mode, offering flexibility in time-based control applications.     Technical Specifications  Condition New/Never Used Surplus Brand Allen-Bradley Category Controls & Indicators Part Number 700-NT Subcategory Time Delay Relay Series Bulletin 700-N Timing Mode (Default) ON-Delay Contact Configuration 1 Normally Open (NO), 1 Normally Closed (NC) Compatibility 700-N Relays (2 to 4-pole) Mounting Type Open Type Power Requirement None (Pneumatic Operation) Standards Compliance UL, CUL, KC Application Time-Delay Relay Control Weight 0.4200 lb       Information About 700-NT The 700-NT timing unit is specifically engineered for integration with the Allen-Bradley Bulletin 700-N relay series. It provides time-delay functionality using pneumatic actuation, eliminating the need for electrical power to operate the timer. The unit includes 1 normally open (NO) and 1 normally closed (NC) timed contact in its configuration and is delivered in ON-delay mode by default. This mode can be quickly changed to OFF-delay by adjusting internal components, offering dual functionality. The timing unit is designed as an open-type module, intended for installation inside protective enclosures. With compliance to UL, CUL, and KC standards, it ensures safe and dependable operation in industrial automation systems. Key Features: ON-Delay Operation (Standard): Timer delays the activation of output contacts after input signal is applied. Convertible to OFF-Delay Mode: Easily reconfigured to delay the deactivation of contacts upon removal of the control signal. Pneumatic Operation: No external power supply required for timing function, ensuring intrinsic reliability. 1 NO / 1 NC Timed Contacts: Supports both make and break delay logic for flexible system control. Open-Type Construction: Designed for mounting within control panels or relay assemblies for environmental protection. 700-N Relay Compatibility: Built to integrate seamlessly with 2- to 4-pole Bulletin 700-N relays. Adjustable Time Range: Offers a selectable time delay range (typically seconds to minutes, depending on the model). Durable Mechanical Design: Engineered for long life and consistent delay performance in demanding industrial applications. Standards Compliant: Meets CUL, KC, and UL requirements for industrial control timing devices. No Electrical Noise: Pneumatic timing eliminates transient signals, ideal for sensitive circuits. The 700-NT offers reliable, adjustable timing functionality for Bulletin 700-N relay systems, delivering flexibility in automation control with both ON- and OFF-delay capability.
