Model  Description 
HD 786 TR1   Configurable temperature transmitter with output 4...20mA

Only two wires are used to transmit both the power supply and the signal: low wiring cost.
Voltage drops on the connection line do not cause errors because the signal transmitted is current and not
voltage: high measurement precision even with small wire sections.
High immunity to disturbances in both common and differential mode: the signal may be transmitted even at
long distances without errors (up to 300 m).
Compatibility with the 4 - 20 mA regulators commonly used in controlling industrial processes.
The device is particularly suitable for industrial applications. In some applications it may be convenient to
screen the cables or lay them in a protective tube separate from the power electronics.
