Measuring Point Change-over Switch
Measuring Point Change-over Switch
Type MUM for 8 or 16 Measuring points
Allgemeines
Measuring point change-over
switches allow the connection of
up to 16 measuring points to 1
measuring device, e.g. an analog
input of a PLC.
The inputs can be selected with
a BCD-Code.
Manual selection can be made
with a code-switch.
In automatic mode, the inputs are polled (tact-time adju-
stabe) and thus be displayed in succession.
When using a measuring point change-over switch, only
1 measuring input is needed to collect multiple values.
Especially with slowly changing signals like temperatures,
measuring every other second is enough.
Expensive inputs for Pt100 or 0-10 V/0-20 mA at PLCs
can be saved.
With the MUM8, alternatively 8
measuring points with common
ground or 4 measuring points
with separated ground can be
switched.
PLC-compatibel. Channel-
selection over 3 bit parallel
(24 V), e.g. PLC or by a code
switch
Optional switching + or -
8 channels (0/4 ... 20 mA, 0
... 10V, Pt 100) with common
ground
4 double-channels (= Pt 100/3-
wire and thermocouples)
Supply-voltage AC 230 V or
DC 24 V
LED-display for selected
channel
Clock time in automatic mode
adjustable 0,5 ... 10 s
plug-in terminals

With the MUM16, alternatively 16
measuring points with common
ground or 8 measuring points
with separated ground can be
switched.
PLC-compatibel. Channel-
selection over 4 bit parallel
(24 V), e.g. PLC or by a
code-switch
Optional switching + or -
Enable-input for using multiple
MUM in parallel
Monitoring of up to 16 signals
for one limit with only 1 limit
switch
16 channels (0/4 ... 20 mA, 0
... 10V, Pt 100) with common
ground
8 double-channels (= Pt 100/
3-wire and thermocouples)
Simple conguration with 3
DIP-switches
Supply AC/DC 24-240 V
LED-display for selected channel
Tact-time in automatic mode adjustable 0,5 ... 10 s
plug-in terminals
Housing for mounting in switchgear cabinets or fuse
boxes, 140 mm wide, mounting height 55 mm
