When it comes to building HVAC control panels and building automation systems, space, installation speed, and reliability all matter. That's why the new Functional Devices TIB® Series DIN Rail Transformers are generating interest among contractors, panel builders, and OEMs looking for a more efficient approach to low-voltage power distribution.
Available through Neuco, the TIB Series combines DIN rail mounting, pluggable terminal connections, UL Listed Class 2 construction, and an industry-leading 10-year warranty into a compact transformer solution designed for modern control panels.
Why the TIB Series Stands Out
Traditional transformers often require dedicated mounting hardware, additional installation time, and can consume valuable panel space. The Functional Devices TIB Series addresses these challenges with a design that integrates seamlessly into standard 35mm DIN rail systems.
Key benefits include:
- Tool-free DIN rail installation
- Secure, precision-fit mounting design
- Compact footprint for space-constrained panels
- Pluggable terminals for faster wiring and troubleshooting
- UL Listed Class 2 construction
- Backed by Functional Devices' 10-year warranty
For contractors and controls professionals, these features translate into faster assembly, easier maintenance, and more organized panel layouts.
Faster Installation and Easier Service
One of the most attractive features of the TIB Series is its pluggable terminal design. Unlike traditional hardwired transformer connections, pluggable terminals simplify installation and make field service significantly easier.
During maintenance, technicians can quickly disconnect and reconnect wiring without removing wire nuts or rewiring the entire transformer. Accessible terminals also make voltage testing and troubleshooting more efficient.
For large BAS or HVAC control projects where serviceability is a priority, this can save valuable labor hours throughout the equipment lifecycle.
Ideal for UL 508A Panel Builders
The TIB Series is UL Listed as a Class 2 transformer, making it a strong choice for panel builders designing UL-compliant control systems.
By combining UL Listed construction with terminal-based connections, the transformers can help support compliance requirements while maintaining a clean and professional panel layout.
