Overview MIQ/CR3; DIQ/CR3
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 out puts to sensors. The
linked current outputs and relay outputs can, for example, be used to
monitor sensors or to outpu t measurement data. Unlinked relay outputs
can be used for general monitoring functions.
With the standard MIQ module housing, the co mbi output module has
the same characteristics as all MIQ modules regarding stability,
leakproofness and weather resist ance. It also pr ovides t he same wi de
variety of installation opt ions (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 S
System Compatible combi output module
ENSOR NET system families.

Cable glands All electric cables are fed from below via prepared openings in the
enclosure of the module. Cable glands with different clampi ng ranges
are included with the mo dule to provid e sealing between the cable and
enclosure as well as for strain relief. Select the matching cable gland
for the respective cable diameter:
Small, c lamping range 4.5 to 1 0 mm. This cable gland is suitabl e for
all IQ S
ENSOR NET sensor cables.
Large, clamping range 7 to 13 mm. This cabl e gland is r equi red for
cable sheaths with an outside diameter of more than 10 mm and is
screwed into the enclosure via an extension piece.
Note
If necessary, you can order more large cable gla nds in a set of 4 pieces
(Model EW/1, Order No. 480 051).

Shorten all wires to be used to the length required for the instal lation
Always fit all the ends of the wires with wire end sleeves before

Any wires that are not used and project into the enclosure must be
cut off as closely as possible to the cable gl and.
Screw a small cable gland with sealing ring in to each remaining free
opening and close it with a blind plug.
Warning
No free wires must be allowed to project into the enclosure.
Otherwise, there is a danger that areas safe to contact could come
into contact with dangerous voltages which could result in life
threatening electric shock when working with t he IQ S

3.4 Connections to the relay and current outputs 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 threaten ing electric shock. Elec trical
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.
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 module. Use an additional output module for such
applications.
Switching voltages and switching currents on the relay
contacts must not exceed the values specified in chapter 6
T
ECHNICAL DATA. Protect electrical cir cuits 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.
After the output module has been installed, it may only be
opened if all external voltages have been switched off
beforehand.

The combi output module has three relays outputs and thre e current
outputs.
Relay outputs operate as openers or closers.
Current outputs provide a current that depends on the measured
value.
On the terminal or Universal Transmitter, you can
assign names to the outputs (with the 2020 XT system only, see
section 4.2).
link outputs with sensors (see section 4.3)
delete links of outputs with sensors (see section 4.4)

Functions of current and
relay outputs
Basic information on how to use relay outputs is given in section 4.1.

4.1 Basic information on relay functions
In this chapter, you will find general basic information concerning the
following relay functions:
Monitoring (see section 4.1.1)
Limit indicator (see section 4.1.2)
Proportional output (see section 4.1.3)
4.1.1 Monitoring
When using a relay for monitor ing, a relay action (Open, Close) occurs
when certain states occur. This function is suitable, e.g. for the
monitoring of errors in the system.
Note
For monitoring functions, use the relay preferably as an opener (see
section 4.5.1). In the cas e of an err or, t he r elay ope ns. As a res ult, the
monitoring function operates even if, e.g. the supply voltage fails.

4.1.2 Limit indicator
With a limit indicator, a relay switches when a speci fied limiting value is
exceeded or undercut.
Limit indicators can be used in the following way:
Monitoring a limiting value using a relay:
when a limiting value (upper o r l ower limiting value) is exceeded or
undercut, a relay switches. The Open or Close relay actions are
possible in each case (see page 4-4).
Monitoring two limiting values using two relays:
If the upper limiting v alue is exceeded or unde rcut, a relay swi tches,
and if the lower limiting value is exceeded or undercut, anothe r relay
switches. The Open or Close rel ay actions are possible in each case
(see page 4-4).
Note
If the simple monitoring function (Open, Close) with one or two relays
is not sufficient, use proportional output (see section 4.1.3).

A switching delay (t) can be set up for each relay for swit ching
processes. This is the time period for which a limiting value must be
exceeded before the relay switches. This prevents frequent switching if
the measured values are close to the limiting value.

4.1.3 Proportional output
In the case of proporti onal output, a relay switc hes cyclic ally on and of f
in a defined measured value range (proportional range). At the same
time, the relay switches with a:
duration of operation that corresponds to the measured value
(pulse-width output, see page 4-7) or
switching frequency (frequency output , see page 4-8).
Proportional outputs can be used in the following way:
Output with one relay:
An output range is defi ned with a Start value and an End value. No
output takes place above and below the output range
(see page 4-6).
Output with two relays:
An output range is defined for each relay with a Start value and an
End value. One relay outputs in the up per output range and a further
relay in the lower output range (see page 4-6).
