TBT7 Series: The Definitive Interface Relay for Modern Industrial Control Systems

In the intricate architecture of modern industrial automation, building management, and process control, the seamless translation of low-power command signals into decisive, high-power action is a fundamental requirement. Programmable Logic Controllers (PLCs), sensors, and touch panels generate precise logic, but they are not designed to handle the electrical demands of motors, solenoids, heaters, or extensive lighting circuits directly. The TBT7 Series Interface Relay stands as the quintessential solution to this universal challenge. Engineered as the robust, intelligent, and utterly reliable link between sensitive control electronics and demanding field loads, this series represents the pinnacle of signal amplification and electrical isolation. It is more than a simple switch; it is a modular system component designed to protect valuable controllers, multiply output points, and execute commands with unwavering speed and durability across a vast array of industrial and commercial applications.

A Comprehensive Platform for Precise Signal and Load Management

The TBT7 Series is architected as a comprehensive family, offering a carefully curated selection of configurations to meet virtually any interfacing need. This systematic approach provides engineers with a single, reliable product line to solve diverse challenges:

· Versatile Contact Configuration: The series offers a range of models providing 1, 2, or 3 isolated SPDT (Single Pole Double Throw) changeover contacts. This allows a single relay to control multiple independent circuits from one input signal, effectively multiplying the output capacity of a controller.

· Dual Current Capacity: To match different load requirements, the series is available with two key current ratings: 8A and 16A at 250V AC (AC1). The 8A models are ideal for solenoid valves, contactor coils, and indicators, while the 16A models can directly control larger loads like motors, heaters, or banks of lighting, simplifying panel design by eliminating the need for additional power contactors in many cases.

Engineered for Uncompromising Performance and Density

In an era where control panel space is at a premium, the TBT7 Series delivers maximum functionality in a minimal footprint while ensuring rapid, reliable operation.

· Ultra-Compact, High-Density Design: All models share an exceptionally compact dimension of 95.5mm x 18mm x 64mm, enabling high-density mounting on standard 35mm DIN rails (EN/IEC 60715). This space efficiency is critical for modern, densely packed control cabinets.

· High-Speed, Reliable Switching: The relay features an exceptionally fast maximum operate time of 40ms, ensuring near-instantaneous response to control signals for time-critical applications. A clear red LED provides immediate visual indication of the output status. Built for millions of cycles, it boasts an impressive mechanical life of 10 million operations and an electrical life (AC1) of 100,000 operations.

Unmatched Flexibility with Universal and Dual-Supply Options

Recognizing the diversity of control voltages in industrial settings, the TBT7 Series offers remarkable power supply flexibility.

· Universal Voltage Coils: Standard models are available with coils for AC/DC 12V, 24V, 48V, AC 110V, and AC 230V, covering the vast majority of global control circuit standards. This simplifies procurement and ensures compatibility.

· Innovative Dual-Supply Models: Select models (e.g., TBT7-216, 316) feature a unique A1-A2-A3 terminal configuration. This allows the same relay to be powered by either AC 230V (across A1-A2) or AC/DC 24V (across A1-A3). This provides unparalleled installation flexibility and future-proofing, allowing the relay to be reused in panels with different control voltages without modification.

Robust, Industrial-Grade Construction for Demanding Environments

Constructed to thrive in harsh conditions, the TBT7 Series is built for unwavering reliability.

· Rugged Environmental Specifications: It operates flawlessly across an operating temperature range of -20°C to +55°C and withstands storage from -35°C to +75°C. The housing provides IP40 protection on the front panel and IP20 protection at the terminals, safeguarding against dust and accidental contact. Its design conforms to Overvoltage Category III and Pollution Degree 2, certifying its suitability for industrial and fixed electrical installations.

· Safe and Easy Installation: The relay can be mounted in any position and accepts solid wire up to 2.5mm² (AWG 12), facilitating straightforward and secure wiring. Its isolation barrier between coil and contacts ensures safe separation of control and power circuits, a critical safety feature.

Critical Applications Across Every Sector

As the universal workhorse of control panels, the TBT7 Series finds application wherever logic meets power:

· Factory Automation: Amplifying PLC outputs to control motor starters, pneumatic valves, conveyor sections, and robotic peripheral devices.

· Process Industry: Interfacing DCS signals with pump controls, agitators, heating elements, and alarm annunciators.

· Building Management (BMS): Executing commands from building controllers to operate HVAC dampers, fans, pumps, and exterior lighting systems.

· Machinery & OEM Equipment: Serving as the reliable output stage in packaging machines, CNC controls, elevators, and medical equipment.
