4. FEATURES
RTD type Pt100 or Pt1000 Input
4 to 20 mA output on current loop
TS-35 DIN rail mounng
+/-0.1% accuracy
Ip40 case
Screw terminals
Easy to use
Supply from current loop
Made in EU
This temperature transmitter is designed to provide a linearised 4-20mA current loop
signal 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 -15C to 150C.

5.1. Installation on TS-35 DIN Rail
Inserting the Module in the Rail:
Removing the Module in the Rail:
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.

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.
