1.2Features 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.

3.3Electrical 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.
sealing ring 20 x 15 x 1 mm
cable gland M16
blind plug
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.
sealing ring 20 x 15 x 1 mm
extension piece M16/M20
sealing ring 24 x 19 x 2 mm

|
General installation |
Observe the following points when attaching connecting wires to the |
instructions |
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. |
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 the IQ SENSOR NET. Always cut off any wires that are not in use as closely as possible to the cable gland.

3.4Connections 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 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.
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 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.
After the output module has been installed, it may only be opened if all external voltages have been switched off beforehand.
Materials required Wire end sleeves, suitable for the connecting wires, with suitable crimping tool
4 x screwed cable gland with sealing ring (scope of delivery of the combi output module).

The combi output module has three relays outputs and three 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)
adjust outputs (see section 4.5 and section 4.6)
check the condition of the outputs (see section 4.7)
Basic information on how to use relay outputs is given in section 4.1.

4.1Basic 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)
4.1.1Monitoring
When using a relay for monitoring, 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 case of an error, the relay opens. As a result, the monitoring function operates even if, e.g. the supply voltage fails.

4.1.2Limit indicator
With a limit indicator, a relay switches when a specified 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 or lower 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 value is exceeded or undercut, a relay switches, and if the lower limiting value is exceeded or undercut, another relay switches. The Open or Close relay 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 switching 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.

4.1.3Proportional output
In the case of proportional output, a relay switches cyclically on and off 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 defined 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 upper output range and a further relay in the lower output range (see page 4-6).
