7 TECHNICAL CHARACTERISTICS
7.1 Power supply
2 wire.
Minimum voltage (TH6): 0.02 Z + 12 (Volt) (Z is the load in the current
loop in Ohm).
The minimum value is 12 VDC for Z=0 Ohm.
Minimum voltage (TH6H): 0..02 (Z+Rext) + 14 (Volt) (Z is the load in the
current loop in Ohm).
The minimum value is 18 VDC for Z=0 Ohm and
Rext=200 Ohm.
Maximum voltage: 36 VDC (for the Ex version see point 8.3)
Consumption: maximum 20 mA
7.2 Outputs
Analog output: 4 - 20 mA, factory calibrated
Maximum load in the 4-20 loop: 1.1 k  (at 36 VDC supply voltage)
7.3 General characteristics
Housing ingress protection: IP65
Cable glands: M12 x 1.5
Ambient temperature: -5 ...+70 ºC
Precision (analog output respect
the magnetic field):
< 0.6 %
6 4-WIRE CONNECTION
If Direct Current power supply for the transmitter is not available in the installation, it will
be necessary to incorporate an additional power supply as in the following figure.
