TBT7 Series: The Pinnacle of Versatility and Precision in Industrial Time Delay Relays

In the intricate world of industrial automation, process control, and building management systems, the precise orchestration of time is a fundamental requirement. From sequencing machine operations and controlling pump cycles to managing lighting schedules and initiating safety delays, the need for reliable, accurate, and flexible timing control is universal. The TBT7 Series Time Delay Relay stands as a definitive solution, engineered to meet the most demanding temporal control challenges with an unparalleled combination of versatility, precision, and robust construction. Far exceeding the capabilities of basic timers, the TBT7 is a microprocessor-based, multi-functional relay designed to serve as the cornerstone of countless timing applications, offering a seamless blend of user-friendly operation and industrial-grade reliability.

Unrivaled Functional Versatility for Diverse Applications

The TBT7 Series distinguishes itself through an exceptional range of built-in timing functions, designated A through J. This comprehensive library allows a single device model to be configured for numerous operational logics without hardware changes. Functions typically encompass:

• On-Delay: Initiates an output after a preset delay following an input signal.
• Off-Delay: Maintains an output for a preset time after the input signal is removed.
• One-Shot (Pulse): Generates a fixed-duration output pulse upon receiving an input signal.
• Flasher: Creates a continuous on/off cycling output.
• Interval Timer: Provides a preset ON time period independent of the input signal duration.
• Asymmetrical Cyclic: Allows for independent setting of ON and OFF times for complex repeating cycles.

This inherent flexibility means the TBT7 can replace a vast inventory of single-function timers, simplifying design, procurement, and maintenance for system integrators and panel builders.

Exceptional Precision and Broad Time Range

Precision is paramount in timing control, and the TBT7 excels with its superior accuracy. Time settings are made via an intuitive front-panel potentiometer, covering an impressively wide range from 0.1 seconds to 10 full days, including dedicated ON and OFF positions. The device boasts a repeat accuracy of 0.2% of the set value, ensuring consistent, dependable operation cycle after cycle. Furthermore, its timing stability is minimally affected by ambient conditions, featuring a low temperature coefficient of only 0.05% per °C. This level of precision ensures that critical processes start and stop exactly when intended, whether for a brief safety interlock or a multi-day irrigation cycle.

Robust Performance and Universal Power Compatibility

Built for the rigors of industrial environments, the TBT7 is designed for global application and long-term durability.

• Universal Power Supply: Its supply terminals (A1-A2) accept a remarkably wide AC/DC voltage range from 12V to 240V at 50/60Hz. This universal compatibility eliminates the need for specific voltage models, streamlining inventory and simplifying integration into diverse control panels worldwide. The device operates reliably within a supply voltage tolerance of -15% to +10%, confirmed by a green LED power indicator.
• High-Capacity, Reliable Output: Available in two configurations—TBT7-A1 with 1x SPDT (Single Pole Double Throw) contact and TBT7-A2 with 2x SPDT contacts—each contact is rated for a substantial 16A at 250V AC (AC1). This allows the relay to directly control significant loads such as contactors, solenoid valves, motors, and lighting circuits. The output status is clearly indicated by a red LED.
• Exceptional Lifespan: Engineered for millions of operations, the relay offers a mechanical life of 10 million cycles and an electrical life (AC1) of 100,000 cycles. A fast maximum reset time of 200ms ensures it is ready for rapid cycling applications.

Compact, Durable Design for Easy Integration

The TBT7 is constructed for practical, hassle-free installation and reliable operation in challenging conditions.

• Compact DIN Rail Mounting: With compact dimensions of 95.5mm x 18mm x 64mm and a lightweight design, it mounts effortlessly on a standard 35mm DIN rail (EN/IEC 60715), conserving valuable panel space. It accepts solid wire up to 2.5mm² (AWG 12), facilitating easy wiring.
• Robust Environmental Specifications: It operates reliably across a temperature range of -20°C to +55°C and can be stored from -35°C to +75°C. The device features a front-panel protection rating of IP40 and terminal protection of IP20, safeguarding against dust and accidental contact. Rated for Overvoltage Category III and Pollution Degree 2, it is suitable for use in industrial and fixed-installation electrical environments.

Certified Safety and Global Compliance

The TBT7 Series is designed and tested to meet rigorous international standards, including EN 61812-1 and IEC 6947-5-1. This certification provides assurance of its safety, performance, and electromagnetic compatibility, making it a trusted and compliant choice for global markets and sensitive applications.

Conclusion: The Intelligent, All-in-One Timing Solution

The TBT7 Series Time Delay Relay represents the convergence of versatility, precision, and durability. By consolidating ten distinct timing functions into one robust, universally-powered device, it offers an unparalleled solution for simplifying control panel design, reducing component inventory, and enhancing system reliability. Its wide timing range, high accuracy, and robust switching capacity make it equally suited for delicate electronic sequencing and heavy-duty load control. For automation engineers, maintenance technicians, and system designers, the TBT7 is more than just a timer; it is a flexible, reliable, and intelligent component that provides the precise temporal control necessary to optimize processes, ensure safety, and drive efficiency in a vast array of industrial and commercial applications. It is the definitive choice where timing is critical.
