Made in EU
This temperature transmitter is designed to provide a linearised 4-20mA current loop
signal output or a 2-10V output, proportional with the temperature characteristic of the
temperature sensor connected on its input. On the input it is possible to connect both 3
wires and 2 wires Pt100 or Pt1000 sensors. This transmitter is suitable for any industrial
application and with its DIN rail mountable enclosure it is easy to instal in electrical
cabinets. The transmitter acquires its supply voltage from the current loop and no
additional power supply needed. The temperature range can be modified only in the
factory and it has to be ordered for a specific range. The default temperature range is -
15°C to 150°C.

5. INSTALLATION AND WIRING
The module is designed to be installed, in a vertical position, on TS-35 DIN rail. For the
best module performance and duration, avoid placing objects that could obstruct the
ventilation. Never install the modules near heat sources.
1) Attach the module in the lower part of the rail, as shown in the left figure below.
2) Press the module upwards.
1) Apply leverage using a screwdriver, as shown in the right figure below.
2) Press the module downwards.
5.2. Connections with Screw Terminals
9
The module has been designed for screw-type terminal electrical connections. Proceed
as follows to make the connections:
1) Strip the cables by 8mm.
2) Insert a screwdriver in hole, unscrewing the screw.
3) Insert the cable in the round hole.
4) Again, use the screwdriver to tight the screw.
5) Remove the screwdriver and make sure that the cable is tightly fastened in the
terminal.

Example 1:
This device can be used for several applications on industrial automation. The models
can have voltage output and current output. It is ideal for industrial enviroment where
temperature measurment is required using Pt100 or Pt1000 temperature sensors.
Suppose that you have a Pt100 temperature sensor and you have to measure the
temperature in a water tank and control the heater of the water tank with a PLC. You can
transmit the measured value to the PLC using our transmitter on a 4-20mA signal where
the 4mA signal will corresponde to -15°C degree and the 20mA signal will corresponde to
150°C degree.
