Description:
TBT7 Series Time Relays: Precision, Versatility, and Robust Performance for Industrial Control
The TBT7 Series Time Relays represent a pinnacle of reliability and flexibility in industrial timing solutions. Designed to meet the rigorous demands of modern automation and control systems, these relays offer exceptional accuracy across an unprecedented time range, from a fraction of a second to several days. With models TBT7-B1/C1 and TBT7-B2/C2, this series provides two fundamental timing functions—Delay ON (B) and Delay OFF (C)—catering to a vast array of application requirements. Built to international standards, including EN61812-1, the TBT7 is engineered for seamless integration and long-term, maintenance-free operation in diverse and challenging environments.
Unmatched Versatility in Timing and Control
The core strength of the TBT7 series lies in its remarkable versatility. The available functions, Delay ON and Delay OFF, allow engineers to configure the relay for tasks such as motor soft-start sequences, conveyor belt control, lighting management, and pump control cycles. The time ranges are exceptionally broad, spanning from 0.1 seconds up to 10 days, and even include instantaneous ON and OFF settings. This wide programmability makes it a single solution for applications requiring brief, precise intervals or long-duration cycles. Time setting is achieved through a user-friendly potentiometer, allowing for intuitive adjustment without the need for complex programming tools.
Technical Precision and Operational Stability
Precision is paramount in timing applications, and the TBT7 delivers with outstanding technical specifications. The time deviation is a minimal 10% of the mechanical setting, while the repeat accuracy is an impressive 0.2% of the set value, ensuring consistent and reliable performance cycle after cycle. Furthermore, the relay maintains this precision under varying temperatures, boasting a low temperature coefficient of just 0.05%/°C, with a reference at 20°C. The supply voltage tolerance of -15% to +10% ensures stable operation even in the face of minor grid fluctuations, making it suitable for regions with unstable power supplies.
Robust Electrical and Mechanical Design
Constructed for durability, the TBT7 features robust output contacts. The models offer either one or two Single-Pole, Double-Throw (SPDT) contacts, each with a high current rating of 16A (AC1) at a switching voltage of 250V AC or 24V DC. This allows the relay to directly control contactors, solenoid valves, and medium-power motors. The mechanical life is rated at 1 x 10^7 operations, and the electrical life (under AC1 conditions) is 1 x 10^5 operations, underscoring its longevity. A fast reset time of under 200ms ensures quick cycle times in rapid-sequence applications.
Universal Integration and User-Friendly Features
Ease of integration is a key design principle. The TBT7 operates on a wide universal supply voltage of AC/DC 12-240V (50-60Hz), eliminating the need for specific models for different control voltages. Its low burden (AC 0.09-3VA / DC 0.05-1.7W) makes it an energy-efficient choice. For immediate operational status, the relay is equipped with a green LED to indicate power supply and a red LED to confirm output switching. It features a compact form factor (95.5x18x64mm) for high-density mounting on standard DIN rails (EN/IEC 60715), in any operating position. With a front panel protection rating of IP40 and terminal protection of IP20, it is safeguarded against dust and accidental contact. It is rated for Overvoltage Category III and Pollution Degree 2, making it suitable for most industrial and commercial electrical environments.
In summary, the TBT7 Series Time Relay is a comprehensive, high-performance solution for engineers and system integrators who require a reliable, accurate, and versatile timing component. Its combination of a wide voltage range, extensive time settings, precise operation, and rugged construction makes it an indispensable component in any control panel.
