1.2 Features of the combi output module
General
characteristics
The combi output module has three current outputs and three relay outputs. You
can link current outputs and relay outputs to sensors. The linked current outputs
and relay outputs can, for example, be used to monitor sensors or to output
measurement data. Unlinked relay outputs can be used for general monitoring
functions.
With the standard MIQ module housing, the combi output module has the same
characteristics as all MIQ modules regarding stability, leakproofness and
weather resistance. It also provides the same wide variety of installation options
(stacked mounting, canopy mounting, tophat rail mounting, etc.).
Instrument types The MIQ/CR3 and DIQ/CR3 combi output modules differ in their compatibility
with the individual IQ SENSOR NET system families.
Terminal strip The combi output module has the following electrical connections on the
terminal strip inside the housing:
3 x relay contact
3 x current output
2 x SENSORNET connection

it was stored under adverse conditions for a lengthy period of time (storing
conditions, see chapter 6 TECHNICAL DATA).
2.3 User qualification
Target group The IQ SENSOR NET system was developed for online analysis. Some mainte-
nance activities, e.g. changing the membrane caps in D.O. sensors, require the
safe handling of chemicals. Thus, we assume that the maintenance personnel
is familiar with the necessary precautions to take when dealing with chemicals
as a result of their professional training and experience.
Special user
qualifications
The following installation activities may only be performed by a qualified electri-
cian:
Connection of the MIQ/CR3; DIQ/CR3 to the power supply.
Connection of external, line voltage-carrying circuits to relay contacts (see

3.4 Installation in the IQ SENSOR NET
The IQ SENSOR NET provides a number of options for integrating the combi
output module mechanically and electrically in the system (stacked mounting,
distributed mounting, etc.). The various types of installation are described in
detail in the INSTALLATION chapter of the system operating manual.
3.5 Electrical connections: General instructions
Cable glands All electric cables are fed from below via prepared openings in the enclosure of
the module. Cable glands with different clamping ranges are included with the
module to provide sealing between the cable and enclosure as well as for strain
relief. Select the matching cable gland for the respective cable diameter:
Small, clamping range 4.5 to 10 mm. This cable gland is suitable for all
IQ SENSOR NET sensor cables.

MIQ/CR3; DIQ/CR3 Installation

ba64107d13 03/2018
Large, clamping range 7 to 13 mm. This cable gland is required for cable
sheaths with an outside diameter of more than 10 mm and is screwed into the
enclosure via an extension piece.
General
installation
instructions
Observe the following points when attaching connecting wires to the terminal
strip
Shorten all wires to be used to the length required for the installation
Always fit all the ends of the wires with wire end sleeves before connecting
them to the terminal strip
Any wires that are not used and project into the enclosure must be cut off as
closely as possible to the cable gland.
Screw a small cable gland with sealing ring into each remaining free opening
and close it with a blind plug.
If necessary, you can order more large cable glands in a set of 4
pieces (Model EW/1, Order No. 480 051).

3.6 Connections to the relay and current outputs
WARNING
No free wires are allowed to project into the housing. Oth-
erwise, there is a danger that areas safe to contact could
come into contact with dangerous voltages. Always cut
off any wires that are not in use as closely as possible to
the cable gland.
WARNING
If external electrical circuits that are subject to the danger
of physical contact are incorrectly connected to the relay
contacts, there may be a danger of life threatening electric
shock. Electrical circuits are regarded to be subject to the
danger of physical contact when there are voltages higher
than the Safety Extra Low Voltage (SELV).
Pay attention to the following points during installation:
Electrical circuits subject to the danger of physical
contact must only be connected by a qualified
electrician.
Electrical circuits subject to the danger of physical
contact must only be connected when they are voltage-
free.
The terminal strip of the MIQ/CR3; DIQ/CR3 output
module has two segments for relay outputs with three
relay connections each (R1-R3 and R4-R6).
If electrical circuits subject to the danger of physical
contact are switched with a relay, no circuit that is not
subject to this danger (e. g. the MIQ/CHV module) may
be operated in the same output segment of the MIQ/
CR3; DIQ/CR3. For such applications use the second
output segment of the MIQ/CR3; DIQ/CR3.
Switching voltages and switching currents on the relay
contacts must not exceed the values specified in
chapter 6 TECHNICAL DATA. Protect electrical circuits
against currents that are too high with an electrical
fuse.
Only single-phase consumers can be switched with the
relays. Under no circumstances must multiphase
consumers be switched with the aid of several relays
(example three-phase current driven pumps). Always
switch multiphase consumers via a protective relay.
The MIQ/CR3; DIQ/CR3 may only be opened after the
installation if all external voltages have been
previously switched off.
