The IQ41x series of intelligent controllers are designed for use
as unitary controllers in building control systems. Full
compatibility with other Trend IQ controllers enables the
IQ41x to integrate the local environmental needs with the bulk
air conditioning system in order to optimise both comfort and
running costs. The controllers have 5 inputs and 6 outputs. The
IQ411 has 6 solid state digital outputs, and the IQ412 has 4 solid
state digital outputs and two 0 to 10 V outputs.
The IQ41x series use Ethernet and TCP/IP networking
technologies with embedded XML. Trend current loop Lan, and
BACnet over IP communications are available as options.
