The IQ®4E controller has 10 universal inputs and 6 analogue
voltage outputs and is expandable up to 192 points (depending
on the controller variant) by adding I/O modules. This flexibility
makes it suitable for a broad range of applications.
The IQ4E controller uses Ethernet and TCP/IP networking
technologies with embedded XML and is fully compatible with
other Trend IQ controllers. The IQ4E supports BACnet over IP
as standard. Trend communications over a current loop LAN is
available as an option. A local PC or display (e.g. IQView4) can
be connected to the RS232 port. A Wallbus port is also provided
for use with room displays.
