Power supply:
according to the model:
- 12-24 VAC (min. 11.4 VAC, max. 27.6 VAC), 50/60 Hz, 3 VA (approximate) isolated or
15 ... 40 VDC, 3 W (approximate) isolated
- 24 VAC (min. 20.4 VAC, max. 27.6 VAC), 50/60 Hz, 3 VA (approximate) non isolated or
20 ... 40 VDC, 2 W (approximate) non isolated
supplied from a class 2 circuit.
The maximum length of the connecting cables of the power supply is 10 m (32.8 ft).
In the models with not isolated power supply, this must galvanically be isolated from the one of the
other devices connected in the network.
Protect the power supply with an UL listed or recognized fuse rated:
- 80 mA-T if the user interface is powered with 15... 40 VDC
- 160 mA-T if the user interface is powered with 12... 19 VAC
- 125 mA-T if the user interface is powered with 19... 24 VAC.
