Common characteristics
of the MIQ modules
 Module lid with hinge
Due to its wide opening angle, the lid provides a large space for
working inside the module (e.g. for connecting lines to the terminal
strip).
 Docking facility
MIQ modules can be mechanically docked onto one another. As a
result, several MIQ modules can be mounted in the form of a stack
to create a single unit (stack mounting). At the same time, docking
enables the MIQ modules to be electrically connected with one
another via the module contacts on the front and back so that no
cabling is required. Even when it is part of a stack, each MIQ module
can be opened. In addition, a terminal component can be docked
onto each free lid front.
 Terminal strip
Further IQ S ENSOR N ET components can be connected by cable to
the terminal strip inside the housing (distributed mounting). The
terminal strip enables IQ sensors to be connected via the SACIQ
sensor connection cable or the IQ S
ENSOR N ET can be further
branched and extended here. Certain MIQ modules have a terminal
strip with further specific connections (e.g. power connection, relay
contacts, current outputs).
 Local identity function
The local identity function is integrated in each MIQ module in the
form of a memory chip. This memory chip can store information such
as the designation of the measurement location and a specific
selection of IQ sensors for the measured value display. This
information is output when a terminal is docked and, thus, e.g.
enables the rapid finding of local IQ sensors for calibration.
 Voltage diagnosis via LEDs
Two LEDs, yellow and red, on the side of the housing are used to
monitor the operational voltage of each MIQ module.
