Functionality in a small footprint

IQ4E is available in 16, 32, 64, 96, 128, 160 and 192-point variants. The ability to upgrade between the point variants provides increased flexibility, and the increased processing performance enables the more complex HVAC applications to be controlled.

IQ4E 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. As with all Trend devices, backwards compatibility is designed in from the outset, naturally the IQ4 communicate with any IQ1, 2 or 3 controller, but now all IQ3 and IQ4 modules are interchangeable for additional protection of customer investment.

Additionally Trend has introduced a new Universal Input /Output module - - 8UIO, allowing every channel to be configured as a digital input, thermistor input, current input, voltage input or voltage output. Once again, this versatility will deliver savings on installation and equipment costs as well as simplifying the potential maintenance stock.

The 105mm IQ4E I/O module is said to be 40% smaller than the IQ3xcite I/O. In addition, the use of vertical connectors means trunking can be situated immediately alongside the controller, saving even more space.

David Field, product manager at Trend Control Systems, commented, ‘With the IQ4E we’ve managed to raise the bar even higher in terms of the features we are able to incorporate into a controller of this size. Designed to meet the multi-faceted demands of today’s customers, it addresses all their requirements for better space utilisation, flexibility and cost effectiveness.’
