The Isolated splitter is usually used in automation systems, where the analog signal of a
measurement device has to be connected into two processing unit. For example a
temperature transmitter 4-20mA output is connected to the input of this device and the
output1 is connected to the PLC, output2 is connected to a display which will show the
temperature value. It can be ordered for 0(4)-20mA, 0-10V or 0-5V standard analog
signals. It ensures also a 4 way galvanic isolation, which mean that the Input, Output1,
Output2 and the power supply is isolated from each other. The galvanic isolation reduces
the impact of interference and ground potential differences.

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.

Example:
This device can be used for several applications on industrial automation. It is ideal for
removing errors caused by noise and signal interference, protecting sensitive equipment
such as a PLC from potential hazards, and converting analog signals. In addition to that,
it sends the same signal for its two isolated outputs.
11. APPLICATIONS
There is a level sensor in a water tank on the field that gives a 0-10V output and you
need to read its measurements both on a PLC (0-10V input) and a logic solver (0-10V
input), and these pieces of equipment need to be isolated for protection and
noise/interference decrease. The sensor will then be connected to a model of this splitter
that allows inputs varying from 0-10V to input and outputs from 0V to 10V, considering the
maximum voltage of the logic solver. Output 1 is connected to the PLC and Output 2 is
connected to the logic solver. So, the level meter output is connected to two different
devices thanks to our splitter converter, both isolated from each other and the sensor. If
there is any interference on the line or maybe an electrical discharge strikes the sensor,
neither the PLC nor the logic solver will be harmed because our device will protect it.
