CONNECTION DIAGRAM
+12V Sensor Excitation
Isolate between the sensor output and the excitation supply.
+24V Two-wire Transmitter Excitation
For use with a smart transmitter (e.g. HART), choose ‘DC voltage input’
and ‘two-wire transmitter excitation’ when ordering, and then connect
as shown below.
Non-smart transmitters are also usable.
The configuration as shown below is possible for sensor outputs
1 – 5V or 4 – 20mA (no signal flow toward (–) direction)
