Trend IQ®4E

Trend’s IQ®4E is the latest addition to the company’s industry leading range of control devices.

Available in 16, 32, 64, 96, 128, 160 and 192-point variants; applications of all sizes can benefit from its best in class technology, while the ability to upgrade between the point variants provides increased flexibility.

Superior processing performance enables even the most complex HVAC applications to be controlled and the IQ®4E also has improved I/O bus capabilities, with an available length of up to 300m and the potential for 30 I/O modules to be configured.

When it comes to allocating room for a BEMS in a commercial building, the size of its constituent parts really does matter.

Trend leads the way in reducing the footprint of its controllers without compromising on features. The IQ®4E is 40% smaller than the IQ®3xcite and, in addition, the use of vertical connectors means trunking can be situated immediately alongside the controller, saving even more space.


With the widest possible combination of input/output (I/O) configurations, Trend’s IQ®4 Internet enabled controllers utilise Ethernet and TCP/IP networking technologies, and utilise the BACnet protocol over IP. The ability to upgrade between point variants provides increased flexibility, and enhanced processing performance enables more complex applications to be controlled.

Trend’s new universal input and analogue output module concept, with 8UIO and 4UIO channel variants, is a significant feature. This allows every channel to be configured as a digital input, thermistor input, current input, voltage input or voltage output. Once again, this versatility will deliver significant savings on installation and equipment costs, as well as simplifying the potential maintenance stock.


Communication is vital and each IQ®4 controller incorporates a web server that can deliver pages to a PC, tablet or mobile phone running an Internet browser. This allows for different customer preferences and requirements – even if they change in the future.

As with all Trend products, backwards compatibility is designed in from the outset. Able to communicate with any IQ®1, IQ®2 or IQ®3 controller, the IQ®4 modules are also interchangeable for additional future proofing, scalability and system longevity – all of which can protect the financial investment in a BEMS.
