2.2. Functional principle
An analog output with 4..20 mA is actuated depending on the selected measuring
range.
The temperature measuring ranges are linearised.
The device configuration takes place via DIP switch.
The power supply can be provided via an internal wide range power supply
(20..125 V DC / 20..253V AC) or via a DC voltage power supply with 24 V DC.
With the DC voltage power supply, the power supply can be done via the plug-in
device terminals or via a carrier rail bus (PowerRail) on the device, depending on
the device type.
2.3.
Connection diagram
Input signals should be connected via separate 2 or 3 core cables.
Grounded leads may cause problems with the not galvanical isolated
analog true value output.
