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.
