Application and short description
The measuring point multiplicator TMU104V measures the temperature at a connected sensor and
transduces it into 4 insulated signals Pt100 (RTD).
Via interface RS485 it can be used as a simulator for up to 4 signals Pt100.
Measuring Point Multiplicator and Transducer:
The temperature of the sensor (resistance or thermocouple), connected to the input, is available as signal
Pt100 (RTD) at 4 insulated outputs.
Thus allows the connection of other sensors than Pt100 to inputs for Pt100 at other devices.
Normally only one input can be connected to a temperature sensor. With help of TMU104 up to 4 devices
(controls, displays, monitoring devices) with inputs Pt100 can be connected to one sensor at the same time.
Simulator for Pt100:
Controlled via interface RS485 (protocol Modbus RTU) the TMU1004V can simulate up to 4 sensors Pt 00
(RTD). This allows the application in equipment, that makes automatic tests and calibrations at devices and
installations with several inputs Pt100.
Overview of functions
•Measuring input Pt100 (RTD), Pt1000, KTY83 / 84 in 2- or 3-wire
•Measuring input thermocouple (types B, E, J, K, L, N, R, S, T)
•Measuring range -199…+850 °C
•4 insulated outputs signal Pt 100 (resistance- signal), connection in 2-, 3- or 4-wire
•Digital display, 3 digits, resolution 1 °C (-19.9 … 99.9 °C: resolution 0,1 °C)
•Storing of MIN- and MAX- values
•Universal supply voltage AC/DC 24-240 V
•Interface RS485 (protocols ZIEHL and Modbus RTU)
•Housing for DIN-rail or wall-mount, 105 mm wide, mounting height 55 mm

Important notes
DANGER!
Hazardous voltage!
Will cause death or serious injury. Turn off and lock out all power
supplying this device before working on this device.
To use the equipment flawless and safe, transport and store properly, install and start professionally
and operate as directed.
Only let persons work with the equipment who are familiar with installation, start and use and who
have appropriate qualification corresponding to their function. They must observe the contents of the
instructions manual, the information which are written on the equipment and the relevant security
instructions for the setting up and the use of electrical units.
The equipment are built according to DIN / EN and checked and leave the plant according to security
in perfect condition. If, in any case the information in the instructions manual is not sufficient, please
contact our company or the responsible representative.
Instead of the industrial norms and regulations written in this instructions manual valid for Europe,
you must observe out of their geographical scope the valid and relevant regulations of the
corresponding country.
Universal power supply.
The device universal power supply works within the range AC/DC 24-240 V.
Before switching on make sure, that the rated supply voltage Us
of the type- plate and the mains voltage are the same.
A circuit-breaker or switch must be situated within easy reach of the
unit and fused. Installation excess current protection should be ≤ 10 A.

Installation
The unit can be installed as follows:
•Installation in switchgear cabinet on 35 mm mounting rail according to EN 60715 for protection against
fire, external environmental conditions and mechanical effects.
•With screws M4 for installation on walls or panel. (additional latch is not included in delivery)
•Connection according to connection plan or type plate.
Failure to comply with the information in this instruction manual will not guarantee the function of the device.
Putting into operation
9.1 General instructions for operation
The decimal point of the last digit shows the operating mode the device is in.
9.2 Display mode
•Decimal point off (display value of measuring input)
9.3 Menu mode
•Decimal point on
•menu mode, select the menu items
Button Up / Down
Press short: Selection of menu item; Change into display mode
Button Set
Press short: Change into parameter setting mode
9.4 Parameter setting mode
•Decimal point blinking
Button Up / Down
Press short/long: Adjustment of parameter value (slow/fast)
Button Set
Press short: Storage of setting and choice of next parameter.
Change into menu mode after the last parameter
9.5 Tips for operation
•When the right decimal point in the 7 segment display is on, the display mode has been left, and the
menu items can be chosen with up/down (menu mode).
•When the right decimal point blinks, you are in the parameter setting mode and can change the setting
with up/down.
•In Parameter setting mode:
oLong pressing on up/down speeds up the changes in the display.
oPressing button up and down at the same time sets values to zero.
•With reset (press set/reset for 2s) the display mode can be reached from every position (exception:
simulation) of the parameter setting mode (the last selected value in is being stored).
The same happens when 30s no key has been pressed ((exception: simulation -> 15 minutes).
9.6 Switch on device
Switch on supply voltage,
All LEDs and displays are on. TMU104V is ready after app. 1 s.
9.7 Configure the sensor input
Starting from the display mode:
Return into the display mode by pressing Set key ≥ 2s
If no entry is made for 30 s, the device also returns to the display mode.
